The nearby San Andreas and Hayward Faults are responsible for much earthquake activity, although neither physically passes through the city itself. The San Andreas Fault caused the earthquakes in 1906 and 1989. Minor earthquakes occur on
870-501: A Standardized Document and Training System for certification of Playground Safety Inspectors. These regulations are nationwide and provide a basis for safe playground installation and maintenance practices. ASTM F1487-07 deals with specific requirements regarding issues such as play ground layout, use zones, and various test criteria for determining play ground safety. ASTM F2373 covers public use play equipment for children 6–24 months old. This information can be applied effectively only by
1044-426: A UN report, warfare is preventing 28 million children worldwide from receiving an education, due to the risk of sexual violence and attacks in schools. Other factors that keep children out of school include poverty, child labor, social attitudes, and long distances to school. Social attitudes toward children differ around the world in various cultures and change over time. A 1988 study on European attitudes toward

1392-623: A common place to live for people employed in Silicon Valley companies such as Apple and Google . The early 2020s featured an exodus of tech companies from Downtown San Francisco in the wake of the COVID-19 pandemic and struggles with homelessness and public drug use. Although some observers have raised the possibility that office vacancies and declining tax revenues could cause San Francisco to enter an economic doom loop , other sources have refuted this broad-based characterization of
1566-647: A flood of treasure seekers (known as "forty-niners," as in "1849"). With their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia , raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of wealth was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. Some of these approximately 500 abandoned ships were used at times as storeships , saloons , and hotels; many were left to rot, and some were sunk to establish title to

San Francisco, which is Spanish for "Saint Francis," takes its name from Mission San Francisco de Asís , which in turn was named after Saint Francis of Assisi . The mission received its name in 1776, when it was founded by the Spanish under the leadership of Padre Francisco Palóu . The city has officially been known as San Francisco since 1847, when Washington Allon Bartlett , then serving as

Such views contrasted with the stridently didactic, Calvinist views of infant depravity. With the onset of industrialisation in England in 1760,
2784-599: A magnet for America's counterculture movement . Beat Generation writers fueled the San Francisco Renaissance and centered on the North Beach neighborhood in the 1950s. Hippies flocked to Haight-Ashbury in the 1960s, reaching a peak with the 1967 Summer of Love . In 1974, the Zebra murders left at least 16 people dead. In the 1970s, the city became a center of the gay rights movement , with
2958-500: A minimal steel framework while providing a web of nylon ropes for children to climb on. Playgrounds with equipment that children may fall off often use rubber mulch on the ground to help cushion the impact. Playgrounds are also made differently for different age groups. Often schools have a playground that is taller and more advanced for older schoolchildren and a lower playground with less risk of falling for younger children. Safety discussions do not normally include an evaluation of
3132-430: A natural setting. Through history, children played in their villages and neighbourhoods, especially in the streets and lanes near their homes. In the 19th century, developmental psychologists such as Friedrich Fröbel proposed playgrounds as a developmental aid, or to imbue children with a sense of fair play and good manners. In Germany, a few playgrounds were erected in connection to schools. Thomas Carlyle called for
3306-539: A new family ideology centred around the upbringing of children. Puritanism stressed the importance of individual salvation and concern for the spiritual welfare of children. The modern notion of childhood with its own autonomy and goals began to emerge during the 18th-century Enlightenment and the Romantic period that followed it. Jean Jacques Rousseau formulated the romantic attitude towards children in his famous 1762 novel Emile: or, On Education . Building on
3480-440: A port and naval base, post-Conquest San Francisco was still a small settlement with inhospitable geography. Situated at the tip of a windswept peninsula without water or firewood, San Francisco lacked most of the basic facilities for a 19th-century settlement. These natural disadvantages forced the town's residents to bring water, fuel and food to the site. Its 1847 population was said to be 459. The California gold rush brought
3654-694: A preventative health measure amongst young people because they promote physical activity at a stage in children's lives when they are active and not yet at risk from opting out of physical activity. Children have devised many playground games and pastimes. But because playgrounds are usually subject to adult supervision and oversight, young children's street culture often struggles to fully thrive there. Research by Robin Moore concluded shown that playgrounds need to be balanced with marginal areas that (to adults) appear to be derelict or wasteground but to children they are areas that they can claim for themselves, ideally

This overprotectiveness may protect the playground owner from lawsuits, but it appears to result in a decreased sense of achievement and increased fears in children. The equipment limitations result in the children receiving less value from

Injuries to the head and face accounted for 49% of injuries to children 0–4, while injuries to the arm and hand accounted for 49% of injuries to children ages 5–14. Approximately 15% of the injuries were classified as severe, with 3% requiring hospitalization. The most prevalent diagnoses were fractures (39%), lacerations (22%), contusions/abrasions (20%), strains/sprains (11%). For children ages 0–4, climbers (40%) had

It acts as a release for them from the pressures of learning during the day. They know that time on the playground is their own time. A type of playground called a playscape can provide children with the necessary feeling of ownership that Moore describes above. Playscapes can also provide parents with
5916-496: A young age. Even though play is considered to be the most important to optimal child development, the environment affects their play and therefore their development. Poor children confront widespread environmental inequities as they experience less social support, and their parents are less responsive and more authoritarian. Children from low income families are less likely to have access to books and computers which would enhance their development. Children's street culture refers to

In English-speaking countries, the legal definition of child generally refers to a minor , in this case as a person younger than the local age of majority (there are exceptions like, for example, the consume and purchase of alcoholic beverage even after said age of majority ), regardless of their physical, mental and sexual development as biological adults . Children generally have fewer rights and responsibilities than adults. They are generally classed as unable to make serious decisions. Child may also describe

It can be seen that playgrounds provide an ideal opportunity for children to master physical skills, such as learning to swing, balance and climb. Personal development may be gained through the enhancement of skills, such as playing, communicating and cooperating with other children and adults in the playground. It can also be seen that public and private playgrounds act as

However, rates of PTSD for children living in chronic conflict conditions varies from 15 to 50 percent. Child protection (also called child welfare) is the safeguarding of children from violence, exploitation, abuse, and neglect. It involves identifying signs of potential harm. This includes responding to allegations or suspicions of abuse, providing support and services to protect children, and holding those who have harmed them accountable. The primary goal of child protection

As a result, they tend to seek out alternative play areas, which may be very unsafe. Risk management is an important life skill, and risk aversion in playgrounds is unhelpful in the long term. Experts studying child development such as Tim Gill have written about

In the 19th century, children younger than seven years old were believed incapable of crime. Children from the age of seven forward were considered responsible for their actions. Therefore, they could face criminal charges, be sent to adult prison, and be punished like adults by whipping, branding or hanging. However, courts at

Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles, sometimes in conjunction with other children or adult caregivers. Undirected play allows children to learn how to work in groups, to share, to negotiate, to resolve conflicts, and to learn self-advocacy skills. However, when play

Child protection also works to prevent future harm by creating policies and systems that identify and respond to risks before they lead to harm. In order to achieve these goals, research suggests that child protection services should be provided in a holistic way. This means taking into account the social, economic, cultural, psychological, and environmental factors that can contribute to

It offers children opportunities for physical (running, jumping, climbing, etc.), intellectual (social skills, community norms, ethics and general knowledge) and emotional development (empathy, compassion, and friendships). Unstructured play encourages creativity and imagination. Playing and interacting with other children, as well as some adults, provides opportunities for friendships, social interactions, conflicts and resolutions. However, adults tend to (often mistakenly) assume that virtually all children's social activities can be understood as "play" and, furthermore, that children's play activities do not involve much skill or effort.

The California Gold Rush triggered a wave of entrepreneurial activity as individuals sought to capitalize on the newfound wealth. The discovery of silver deposits, notably the Comstock Lode in Nevada in 1859, further fueled rapid population growth and economic expansion. San Francisco, as
13398-457: The San Francisco economy. Large numbers of entrepreneurs and computer application developers moved into the city, followed by marketing, design, and sales professionals, changing the social landscape as once poorer neighborhoods became increasingly gentrified . Demand for new housing and office space ignited a second wave of high-rise development, this time in the South of Market district. By 2000,
13572-455: The Spanish ship San Carlos , commanded by Juan Manuel de Ayala , became the first ship to anchor in the bay. Soon after, on March 28, 1776, Anza established the Presidio of San Francisco . On October 9, Mission San Francisco de Asís , also known as Mission Dolores, was founded by Padre Francisco Palóu . In 1794, the Presidio established the Castillo de San Joaquín , a fortification on

The larger San Jose–San Francisco–Oakland combined statistical area , the fifth-largest urban region in the U.S., had a 2023 estimated population of over 9 million. Prior to European settlement , the modern city proper was inhabited by the Yelamu , who spoke a language now referred to as Ramaytush Ohlone . On June 29, 1776, settlers from New Spain established
13920-532: The United States, emergency departments treat more than 200,000 children ages 14 and younger for playground-related injuries. Approximately 156,040 (75.8%) of the 1999 injuries occurred on equipment designed for public use; 46,930 (22.8%) occurred on equipment designed for home use; and 2,880 (1.4%) occurred on homemade playground equipment (primarily rope swings). From January 1990 to August 2000, CPSC received reports of 147 deaths to children younger than 15 that involved playground equipment. Girls were involved in
14094-560: The Vietnam War , and other factors led to the Summer of Love and the gay rights movement, cementing San Francisco as a center of liberal activism in the United States . San Francisco and the surrounding San Francisco Bay Area are a global center of economic activity and the arts and sciences, spurred by leading universities , high-tech , healthcare, finance, insurance, real estate, and professional services sectors. As of 2020 ,
14268-666: The age of 18 in sub-Saharan Africa, followed by South Asia at 30%. Lower levels were found in Latin America and Caribbean (25%), the Middle East and North Africa (18%), and Eastern Europe and Central Asia (11%), while rates in Western Europe and North America were minimal. Child marriage is more prevalent with girls, but also involves boys. A 2018 study in the journal Vulnerable Children and Youth Studies found that, worldwide, 4.5% of males are married before age 18, with
14442-435: The age of majority. In Singapore , for example, a child is legally defined as someone under the age of 14 under the "Children and Young Persons Act" whereas the age of majority is 21. In U.S. Immigration Law, a child refers to anyone who is under the age of 21. Some English definitions of the word child include the fetus (sometimes termed the unborn ). In many cultures, a child is considered an adult after undergoing
14616-437: The amelioration of risk factors for disease, avoidance of weight gain, achieving a peak bone mass and mental well-being. Exercise programmes "may have short term beneficial effects on self esteem in children and adolescents" although high-quality trials are lacking. Commentators argue that the quality of a child's exercise experience can affect their self-esteem. Ajzen TPB (1991) promotes the notion that children's self-esteem
14790-464: The area. Further development is taking place just to the south in Mission Bay area, a former railroad yard, which now has a second campus of the University of California, San Francisco and Chase Center , which opened in 2019 as the new home of the Golden State Warriors . West of downtown, across Van Ness Avenue , lies the large Western Addition neighborhood, which became established with
14964-597: The assurance of their child's safety and wellbeing, which may not be prevalent in an open field or wooded area. In the UK, several organisations exist that help provide funding for schools and local authorities to construct playgrounds. These include the Biffa Award, which provides funding under the Small Grants Scheme; Funding Central, which offers support for voluntary organisations and social enterprises; and
15138-547: The beginning of adulthood varies by country and by function, and even within a single nation-state or culture there may be different ages at which an individual is considered to be mature enough to be entrusted by society with certain tasks. During the European Renaissance , artistic depictions of children increased dramatically, which did not have much effect on the social attitude toward children, however. The French historian Philippe Ariès argued that during
15312-597: The beginning of the assimilation of the Ramaytush people, and the decline of their language and culture. The Spanish Empire claimed San Francisco as part of Las Californias , a province of the Viceroyalty of New Spain . The Spanish first arrived in what is now San Francisco on November 2, 1769, when the Portolá expedition led by Don Gaspar de Portolá and Juan Crespí arrived at San Francisco Bay . Having noted
15486-539: The book The Cult of Childhood . Since then, historians have increasingly researched childhood in past times. In 2006, Hugh Cunningham published the book Invention of Childhood , looking at British childhood from the year 1000, the Middle Ages , to what he refers to as the Post War Period of the 1950s, 1960s and 1970s. Childhood evolves and changes as lifestyles change and adult expectations alter. In
15660-426: The capture, U.S. forces appointed both José de Jesús Noé and Washington Allon Bartlett to serve as co- alcaldes (mayors), while the conquest continued on in the rest of California. On January 30, 1847, Mayor Bartlett ordained that the city should officially change its name from "Yerba Buena" to "San Francisco", as the former name was only locally recognized and the latter name was in use on international maps. There
15834-697: The centrality of children found that Italy was more child-centric and the Netherlands less child-centric, with other countries, such as Austria, Great Britain, Ireland and West Germany falling in between. In 2013, child marriage rates of female children under the age of 18 reached 75% in Niger, 68% in Central African Republic and Chad, 66% in Bangladesh, and 47% in India . According to a 2019 UNICEF report on child marriage, 37% of females were married before
16008-546: The child becomes less dependent on parental assistance for basic needs, early childhood continues approximately until the age of 5 or 6. However, according to the National Association for the Education of Young Children , early childhood also includes infancy. At this stage children are learning through observing, experimenting and communicating with others. Adults supervise and support the development process of
16182-441: The child on a low piece of equipment, designed to reduce the incidence of injuries from falls, experiences no such thrill, sense of mastery, or accomplishment. Additionally, a lack of experience with heights as a child is associated with increased acrophobia (fear of heights) in adults. The appearance of safety encourages unreasonable risk-taking in children, who might take more reasonable risks if they correctly understood that it
16356-499: The child's imagination. Lewis Carroll 's fantasy Alice's Adventures in Wonderland , published in 1865 in England, was a landmark in the genre; regarded as the first "English masterpiece written for children", its publication opened the "First Golden Age" of children's literature. The latter half of the 19th century saw the introduction of compulsory state schooling of children across Europe, which decisively removed children from
16530-467: The child, which then will lead to the child's autonomy. Also during this stage, a strong emotional bond is created between the child and the care providers. The children also start preschool and kindergarten at this age: and hence their social lives. Middle childhood begins at around age 7, and ends at around age 9 or 10. Together, early and middle childhood are called formative years. In this middle period, children develop socially and mentally. They are at
16704-476: The city and burned out of control for several days. With water mains out of service, the Presidio Artillery Corps attempted to contain the inferno by dynamiting blocks of buildings to create firebreaks. More than three-quarters of the city lay in ruins, including almost all of the downtown core. Contemporary accounts reported that 498 people died, though modern estimates put the number in
16878-521: The city as a whole, asserting that the issues of concern are restricted primarily to the urban core of San Francisco. As of March 2024, Union Square was in "sorry shape" and had lost its traditional position as the Bay Area's regional shopping hub to Westfield Valley Fair in San Jose. The Ferry Station Post Office Building , Armour & Co. Building , Atherton House , and YMCA Hotel are historic buildings among dozens of historical landmarks in
17052-414: The city is still home to numerous companies inside and outside of technology, including Salesforce , Uber , Airbnb , X , Levi's , Gap , Dropbox , and Lyft . In 2022, San Francisco had more than 1.7 million international visitors – the fifth-most visited city from abroad in the United States after New York City, Miami , Orlando , and Los Angeles – and approximately 20 million domestic visitors for
17226-635: The city proper. In 1856, San Francisco became a consolidated city-county . After three-quarters of the city was destroyed by the 1906 earthquake and fire , it was quickly rebuilt, hosting the Panama–Pacific International Exposition nine years later. In World War II , it was a major port of embarkation for naval service members shipping out to the Pacific Theater . In 1945, the United Nations Charter

Earlier in San Francisco's history, the uninhabited area on the northeastern side of San Francisco was called El Paraje de Yerba Buena , after the herb that was growing abundantly there. The name Yerba Buena continues to be used in locations in
17748-417: The city's population reached new highs, surpassing the previous record set in 1950. When the bubble burst in 2001 and again in 2023, many of these companies folded and their employees were laid off. Yet high technology and entrepreneurship remain mainstays of the San Francisco economy. By the mid-2000s (decade), the social media boom had begun, with San Francisco becoming a popular location for tech offices and
17922-576: The city's southern border, the Excelsior District is one of the most ethnically diverse neighborhoods in San Francisco. The Bayview-Hunters Point in the far southeast corner of the city is one of the poorest neighborhoods, though the area has been the focus of several revitalizing and urban renewal projects. The construction of the Twin Peaks Tunnel in 1918 connected southwest neighborhoods to downtown via streetcar, hastening
18096-571: The city, according to the National Register of Historic Places listings in San Francisco . San Francisco is located on the West Coast of the United States , at the north end of the San Francisco Peninsula and includes significant stretches of the Pacific Ocean and San Francisco Bay within its boundaries.

18270-865: The city, such as on Yerba Buena Island and in the Yerba Buena Center for the Arts and Yerba Buena Gardens . While people residing outside the San Francisco Bay Area use nicknames including "Frisco" and "San Fran", local residents in the Bay Area sometimes refer to San Francisco as "the City" or "SF". The choice of nickname a person uses is a common way for locals to distinguish long-time residents from tourists and recent arrivals. "San Fran" and "Frisco" are sometimes considered controversial as nicknames among San Francisco residents. The earliest archeological evidence of human habitation of
18444-432: The city. Also included are the uninhabited Farallon Islands , 27 miles (43 km) offshore in the Pacific Ocean. The mainland within the city limits roughly forms a "seven-by-seven-mile square," a common local colloquialism referring to the city's shape, though its total area, including water, is nearly 232 square miles (600 km ). There are more than 50 hills within the city limits. Some neighborhoods are named after
18618-524: The concept of the ’junk playground’ - where the equipment was constructed from the recycled junk and rubble left over from the Blitz . She campaigned for facilities for children growing up in the new high-rise developments in Britain's cities and wrote a series of illustrated books on the subject of playgrounds, and at least one book on adventure playgrounds, spaces for free creativity by children, which helped
18792-515: The country at the time. His financial empire, however, collapsed in 1875 as a result of the Panic of 1873 , triggering a major economic crisis in San Francisco. Development of the Port of San Francisco and the establishment in 1869 of overland access to the eastern U.S. rail system via the newly completed Pacific Railroad (the construction of which the city only reluctantly helped support ) helped make
18966-690: The cumulative culture created by young children and is sometimes referred to as their secret world . It is most common in children between the ages of seven and twelve. It is strongest in urban working class industrial districts where children are traditionally free to play out in the streets for long periods without supervision. It is invented and largely sustained by children themselves with little adult interference. Young children's street culture usually takes place on quiet backstreets and pavements, and along routes that venture out into local parks , playgrounds , scrub and wasteland, and to local shops. It often imposes imaginative status on certain sections of
19140-683: The development of West Portal , and nearby affluent Forest Hill and St. Francis Wood . Further west, stretching all the way to the Pacific Ocean and north to Golden Gate Park lies the vast Sunset District , a large middle-class area with a predominantly Asian population. The northwestern quadrant of the city contains the Richmond , a mostly middle-class neighborhood north of Golden Gate Park, home to immigrants from other parts of Asia as well as many Russian and Ukrainian immigrants. Together, these areas are known as The Avenues . These two districts are each sometimes further divided into two regions:
19314-499: The developmental period of infancy and puberty. Legally, the term child may refer to anyone below the age of majority or some other age limit. The United Nations Convention on the Rights of the Child defines child as, "A human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier." This is ratified by 192 of 194 member countries. The term child may also refer to someone below another legally defined age limit unconnected to
19488-415: The divergence between high-minded romantic ideals of childhood and the reality of the growing magnitude of child exploitation in the workplace, became increasingly apparent. By the late 18th century, British children were specially employed in factories and mines and as chimney sweeps , often working long hours in dangerous jobs for low pay. As the century wore on, the contradiction between the conditions on
19662-449: The educational level of women, ranging from 5–8 children in women without education to less than 2 in women with 12 or more years of education. Emergencies and conflicts pose detrimental risks to the health , safety, and well-being of children. There are many different kinds of conflicts and emergencies, e.g. wars and natural disasters . As of 2010 approximately 13 million children are displaced by armed conflicts and violence around
19836-509: The emergence of The Castro as an urban gay village , the election of Harvey Milk to the Board of Supervisors , and his assassination , along with that of Mayor George Moscone , in 1978. Bank of America , now based in Charlotte , North Carolina , was founded in San Francisco; the bank completed 555 California Street in 1969. The Transamerica Pyramid was completed in 1972, igniting
20010-467: The establishment of public playgrounds within industrial cities such as Manchester , England, in Past and Present (1843), saying that "every toiling Manchester" ought to have "a hundred acres or so of free greenfield, with trees on it, conquered, for its little children to disport in". Manchester became the site of the first purpose-built public-access playground, which opened in a park in 1859. However, it
20184-774: The excavation of the Yerba Buena Tunnel through Yerba Buena Island during the construction of the Bay Bridge. Such land tends to be unstable during earthquakes. The resulting soil liquefaction causes extensive damage to property built upon it, as was evidenced in the Marina district during the 1989 Loma Prieta earthquake . A few natural lakes and creeks ( Lake Merced , Mountain Lake , Pine Lake , Lobos Creek , El Polin Spring ) are within parks and remain protected in what
20358-518: The exploitation of children at the workplace The modern attitude to children emerged by the late 19th century; the Victorian middle and upper classes emphasized the role of the family and the sanctity of the child – an attitude that has remained dominant in Western societies ever since. The genre of children's literature took off, with a proliferation of humorous, child-oriented books attuned to
20532-520: The fact that there were no churches to be found, prompted missionaries like William Taylor to come to San Francisco where he began preaching in the streets, using an upright barrel as his pulpit. Taylor was able to garner enough generous donations from successful gold miners with which he used to build a church. One of the most influential figures of this era was William Chapman Ralston . A shrewd banker and investor, Ralston amassed considerable wealth and influence in San Francisco. He gained control over
20706-497: The famous " Painted Ladies ," standing alongside Alamo Square . To the south, near the geographic center of the city is Haight-Ashbury , famously associated with 1960s hippie culture. The Haight is now home to some expensive boutiques and a few controversial chain stores, although it still retains some bohemian character. North of the Western Addition is Pacific Heights , an affluent neighborhood that features
20880-610: The first land grant in Yerba Buena: to William Richardson , a naturalized Mexican citizen of English birth. Richardson had arrived in San Francisco aboard a whaling ship in 1822. In 1825, he married Maria Antonia Martinez, eldest daughter of the Californio Ygnacio Martínez . Yerba Buena began to attract American and European settlers; an 1842 census listed 21 residents (11%) born in the United States or Europe, as well as one Filipino merchant. Following
21054-418: The flawed, human side of authority figures). Alongside that, they may begin to develop a sense of self - identity , and to have increased feelings of independence : 'may feel an individual, no longer "just one of the family."' Adolescence is usually determined to be between the onset of puberty and legal adulthood: mostly corresponding to the teenage years (13–19). However, puberty usually begins before
21228-518: The gateway to the goldfields, experienced a surge in population and commercial activity. However, the influx of fortune seekers also brought challenges. Lawlessness was rampant, and the Barbary Coast district became synonymous with vice, attracting criminals, prostitutes, and illicit activities, including but not limited to prostitution, bootlegging , and gambling. The rapidly growing population, with its lawlessness, gambling and other vices, and
21402-838: The global level, Article 13 of the United Nations ' 1966 International Covenant on Economic, Social and Cultural Rights (ICESCR) recognizes the right of everyone to an education. Education is compulsory in most places up to a certain age, but attendance at school may not be, with alternative options such as home-schooling or e-learning being recognized as valid forms of education in certain jurisdictions. Children in some countries (especially in parts of Africa and Asia) are often kept out of school, or attend only for short periods. Data from UNICEF indicate that in 2011, 57 million children were out of school; and more than 20% of African children have never attended primary school or have left without completing primary education. According to
21576-464: The ground for poor children and the middle-class notion of childhood as a time of simplicity and innocence led to the first campaigns for the imposition of legal protection for children. British reformers attacked child labor from the 1830s onward, bolstered by the horrific descriptions of London street life by Charles Dickens . The campaign eventually led to the Factory Acts , which mitigated
21750-906: The highest incidence rates, followed by slides (33%). For children ages 5–14, climbing equipment (56%) had the highest incidence rates, followed by swings (24%). Most injuries on public playground equipment were associated with climbing equipment (53%), swings (19%), and slides (17%). Falls to the surface was a contributing factor in 79% of all injuries. On home equipment, 81% were associated with falls. In 1995, playground-related injuries among children ages 14 and younger cost an estimated $ 1.2 billion. On public playgrounds, more injuries occur on climbers than on any other equipment. On home playgrounds, swings are responsible for most injuries. Playgrounds in low-income areas have more maintenance-related hazards than playgrounds in high-income areas. For example, playgrounds in low-income areas had significantly more trash, rusty play equipment, and damaged fall surfaces. As
21924-457: The hill on which they are situated, including Nob Hill , Potrero Hill , and Russian Hill . Near the geographic center of the city, southwest of the downtown area, are a series of less densely populated hills. Twin Peaks , a pair of hills forming one of the city's highest points, forms an overlook spot. San Francisco's tallest hill, Mount Davidson , is 928 feet (283 m) high and is capped with
22098-562: The homes built by wealthy San Franciscans in the wake of the 1906 earthquake. Directly north of Pacific Heights facing the waterfront is the Marina , a neighborhood popular with young professionals that was largely built on reclaimed land from the Bay. In the southeast quadrant of the city is the Mission District —populated in the 19th century by Californios and working-class immigrants from Germany, Ireland, Italy, and Scandinavia. In
22272-469: The idea spread worldwide. Playgrounds were an integral part of urban culture in the USSR . In the 1970s and 1980s, there were playgrounds in almost every park in many Soviet cities. Playground apparatus was reasonably standard all over the country; most of them consisted of metallic bars with relatively few wooden parts, and were manufactured in state-owned factories. Some of the most common constructions were
22446-403: The ideas of John Locke and other 17th-century thinkers, Jean-Jaques Rousseau described childhood as a brief period of sanctuary before people encounter the perils and hardships of adulthood. Sir Joshua Reynolds ' extensive children portraiture demonstrated the new enlightened attitudes toward young children. His 1788 painting The Age of Innocence emphasizes the innocence and natural grace of
22620-538: The larger Port of Oakland . The city began to lose industrial jobs and turned to tourism as the most important segment of its economy. The suburbs experienced rapid growth, and San Francisco underwent significant demographic change, as large segments of the white population left the city, supplanted by an increasing wave of immigration from Asia and Latin America. From 1950 to 1980, the city lost over 10 percent of its population. Over this period, San Francisco became
22794-586: The main concern when building with wood material. Wet weather is also a threat to children playing on wooden structures. Most woods are treated and do not wear terribly fast, but with enough rain, wooden playgrounds can become slippery and dangerous for children to be on. In the United States, the Consumer Product Safety Commission and the American National Standards Institute have created
22968-518: The metropolitan area, with 4.5 million residents, ranked 5th by GDP ($ 874 billion) and 2nd by GDP per capita ($ 131,082) across the OECD countries, ahead of global cities like Paris , London , and Singapore . It is the fourth-largest by aggregate income and economic output, with a GDP of $ 729 billion in 2022 . The wider San Jose–San Francisco–Oakland Combined Statistical Area is the nation's fifth-most populous, with around nine million residents, and
23142-419: The missions were made to divest themselves of their extensive landholdings and emancipate the indigenous people under their control. As part of the process of secularization, Governor José Figueroa opened up San Francisco to civilian settlement. Prior to secularization, the only settlements in San Francisco had been the military settlement at the Presidio and the religious settlement at Mission Dolores. In 1835,
23316-407: The modern era, many adults believe that children should not have any worries or work, as life should be happy and trouble-free. Childhood is seen as a mixture of simplicity, innocence, happiness, fun, imagination, and wonder. It is thought of as a time of playing, learning, socializing, exploring, and worrying in a world without much adult interference. A "loss of innocence" is a common concept, and
23490-419: The most beneficial type of play. Exciting, engaging and challenging playground equipment is important to keep children happy while still developing their learning abilities. These should be developed in order to suit different groups of children for different stages of learning, such as specialist playground equipment for nursery & pre-school children teaching them basic numeracy & vocabulary, to building
23664-445: The over-protective bias in provision for children, particularly with playgrounds. Instead of a constructed playground, allowing children to play in a natural environment such as open land or a park is sometimes recommended; children gain a better sense of balance playing on uneven ground, and learn to interpret the complexity and signals of nature more effectively. Playgrounds can be: Child A child ( pl. children )
23838-484: The period of Mexican rule , although it was not until 1833 that the missions would be secularized. Agricultural land became largely privatized as ranchos , as was occurring in other parts of California. Coastal trade increased, including a half-dozen barques from various Atlantic ports which regularly sailed in California waters. With the enactment of the Mexican Secularization Act of 1833 ,
24012-687: The physical, mental and social well-being of children. Maintaining children's health implies offering them healthy foods, insuring they get enough sleep and exercise, and protecting their safety. Children in certain parts of the world often suffer from malnutrition , which is often associated with other conditions, such diarrhea, pneumonia and malaria. Child protection, according to UNICEF, refers to "preventing and responding to violence, exploitation and abuse against children – including commercial sexual exploitation , trafficking , child labour and harmful traditional practices, such as female genital mutilation /cutting and child marriage ". The Convention on
24186-538: The places and spaces in which children live. Nature Deficit Disorder, a term coined by Richard Louv in his 2005 book Last Child in the Woods , refers to the trend in the United States and Canada towards less time for outdoor play, resulting in a wide range of behavioral problems. With increasing use of cellphones, computers, video games and television, children have more reasons to stay inside rather than outdoors exploring. “The average American child spends 44 hours
24360-441: The play time. The enclosed, padded, constrained, low structures prevent the child from taking risks and developing a sense of mastery over his or her environment. Successfully taking a risk is empowering to children. For example, a child climbing to the top of a tall jungle gym feels happy about successfully managing the challenging climb to the top, and he experiences the thrill of being in a precarious, high position. By contrast,
24534-637: The posing child and soon became a public favourite. The idea of childhood as a locus of divinity, purity, and innocence is further expounded upon in William Wordsworth 's "Ode: Intimations of Immortality from Recollections of Early Childhood", the imagery of which he "fashioned from a complex mix of pastoral aesthetics, pantheistic views of divinity, and an idea of spiritual purity based on an Edenic notion of pastoral innocence infused with Neoplatonic notions of reincarnation". This Romantic conception of childhood, historian Margaret Reeves suggests, has
24708-507: The post-installation inspections recommended by EN 1176. Because the majority of playground injuries are due to falls from equipment, injury prevention efforts are primarily directed at reducing the likelihood of a child falling and reducing the likelihood of a severe injury if the child does fall. This is done by: How effective these strategies are at preventing injuries is debated by experts, because when playgrounds are made from padded materials, children often take more risks. Each year in
24882-406: The primary port of embarkation for service members shipping out to the Pacific Theater of Operations . The explosion of jobs drew many people, especially African Americans from the South , to the area. After the end of the war, many military personnel returning from service abroad and civilians who had originally come to work decided to stay. The United Nations Charter creating the United Nations
25056-605: The quality of housing after the earthquake. The earthquake hastened development of western neighborhoods that survived the fire, including Pacific Heights , where many of the city's wealthy rebuilt their homes. In turn, the destroyed mansions of Nob Hill became grand hotels. City Hall rose again in the Beaux Arts style, and the city celebrated its rebirth at the Panama–Pacific International Exposition in 1915. During this period, San Francisco built some of its most important infrastructure. Civil Engineer Michael O'Shaughnessy
25230-465: The requirements for surfaces used in playgrounds. For each material type and height of equipment it specifies a minimum depth of material required. EN 1176 covers playground equipment standards. In the UK, playground inspectors can sit the examinations of the Register of Play Inspectors International at the three required levels - routine, operational and annual. Annual inspectors are able to undertake
25404-634: The risk of harm for individual children and their families. Collaboration across sectors and disciplines to create a comprehensive system of support and safety for children is required. It is the responsibility of individuals, organizations, and governments to ensure that children are protected from harm and their rights are respected. This includes providing a safe environment for children to grow and develop, protecting them from physical, emotional and sexual abuse, and ensuring they have access to education, healthcare, and resources to fulfill their basic needs. San Francisco San Francisco , officially
25578-401: The second-most densely populated major U.S. city behind New York City and the fifth-most densely populated U.S. county , behind four of New York City's boroughs . Among the 92 U.S. cities proper with over 250,000 residents, San Francisco is ranked first by per capita income and sixth by aggregate income as of 2022. San Francisco anchors the 13th most populous metropolitan statistical area in
25752-542: The several thousands. More than half of the city's population of 400,000 was left homeless. Refugees settled temporarily in makeshift tent villages in Golden Gate Park, the Presidio, on the beaches, and elsewhere. Many fled permanently to the East Bay . Jack London is remembered for having famously eulogized the earthquake: "Not in history has a modern imperial city been so completely destroyed. San Francisco
25926-429: The skill of risk assessment , and a completely safe environment does not allow that. Sometimes the safety of playgrounds is disputed in school or among regulators.
