According to the United Nations Statistics Division : There is no established convention for the designation of "developed" and "developing" countries or areas in the United Nations system. And it notes that: The designations "developed" and "developing" are intended for statistical convenience and do not necessarily express

Studies have shown a positive correlation between Foxp3 methylation and children's exposure to NO 2 , CO, and PM 2.5 . Furthermore, any amount of exposure to high levels of air pollution have shown long term effects on the Foxp3 region. Developed world A developed country , or advanced country ,
405-536: A farmer was described as "hot and exhausting". "Everyone says the farmer works the hardest but gets the least amount of money". In an effort to counter this impression, the Agriculture Department of Thailand is seeking to promote the impression that farming is "honorable and secure". However, in Thailand, urbanization has also resulted in massive increases in problems such as obesity. Shifting from
486-521: A greater risk for obesity, diabetes and related chronic disease. Overall, body mass index and cholesterol levels increase sharply with national income and the degree of urbanization. [40] Food deserts in the United States are most commonly found in low-income and predominately African American neighbourhoods. One study on food deserts in Denver , Colorado found that, in addition to minorities,

Food deserts in developed countries often correspond to areas with a high density of fast food chains and convenience stores that offer little to no fresh food. Urbanization has been shown to be associated with the consumption of less fresh fruits, vegetables, and whole grains and a higher consumption of processed foods and sugar-sweetened beverages. Poor access to healthy food and high intakes of fat, sugar and salt are associated with

729-451: A growing increase for addressing other areas of life cycle consumption has occurred from initial stage reduction to heat recovery and recycling of materials. For example, concerns for mass consumption and fast fashion have moved to the forefront of the urban consumers' priorities. Aside from environmental concerns (e.g. climate change effects), other urban concerns for waste management are public health and land access. Urbanization can have
810-459: A higher content of meat, sugars, refined grains and fats. Urban residents typically have reduced time available for at-home food preparation combined with increased disposable income, facilitating access to convenience foods and ready-to-eat meals. One such effect is the formation of food deserts . Nearly 23.5 million people in the United States lack access to supermarkets within one mile of their home. Several studies suggest that long distances to

Nevertheless, the UN Trade and Development considers that this categorization can continue to be applied: The developed economies broadly comprise Northern America and Europe, Israel, Japan, the Republic of Korea, Australia, and New Zealand. Terms linked to the concept developed country include "advanced country", "industrialized country", "more developed country" (MDC), "more economically developed country" (MEDC), " Global North country", " first world country", and "post-industrial country". The term industrialized country may be somewhat ambiguous, as industrialisation

Habitat fragmentation does not destroy the habitat, as seen in habitat loss , but rather breaks it apart with things like roads and railways This change may affect a species ability to sustain life by separating it from the environment in which it is able to easily access food, and find areas that they may hide from predation With proper planning and management, fragmentation can be avoided by adding corridors that aid in
1053-473: A more acidic environment. Rapid growth of communities creates new challenges in the developed world and one such challenge is an increase in food waste also known as urban food waste. Food waste is the disposal of food products that can no longer be used due to unused products, expiration, or spoilage. The increase of food waste can raise environmental concerns such as increase production of methane gases and attraction of disease vectors . Landfills are
1134-584: A negative impact on population health particularly affecting people's susceptibility to asthma. In low and middle income countries many factors contribute to the high numbers of people with asthma. Similar to areas in the United States with increasing urbanization, people living in growing cities in low income countries experience high exposure to air pollution, which increases the prevalence and severity of asthma among these populations. Links have been found between exposure to traffic-related air pollution and allergic diseases. Children living in poor, urban areas in
1215-673: A population of 967,604 (2020), the Omaha metropolitan area is the most populous in both Nebraska and Iowa (although the Des Moines–West Des Moines MSA is the largest MSA centered entirely in Iowa), and is the 58th most populous MSA in the United States. The 2003 revision to metropolitan area definitions was accompanied by the creation of micropolitan areas and combined statistical areas . Fremont , in Dodge County, Nebraska ,
1296-646: A result of individual, collective and state action. Living in a city can be culturally and economically beneficial since it can provide greater opportunities for access to the labour market, better education, housing, and safety conditions, and reduce the time and expense of commuting and transportation. Conditions like density, proximity, diversity, and marketplace competition are elements of an urban environment that deemed beneficial. However, there are also harmful social phenomena that arise: alienation, stress, increased cost of living, and mass marginalization that are connected to an urban way of living. Suburbanization , which
1377-408: A rural environment to an urbanized community also caused a transition to a diet that was mainly carbohydrate-based to a diet higher in fat and sugar, consequently causing a rise in obesity. City life, especially in modern urban slums of the developing world, is certainly hardly immune to pestilence or climatic disturbances such as floods, yet continues to strongly attract migrants. Examples of this were
1458-543: A vector to spread to humans. An example of this could be dengue fever. Urbanization has also been associated with an increased risk of asthma as well. Throughout the world, as communities transition from rural to more urban societies, the number of people affected by asthma increases. The odds of reduced rates of hospitalization and death from asthmas has decreased for children and young adults in urbanized municipalities in Brazil. This finding indicates that urbanization may have
1539-611: Is a sovereign state that has a high quality of life , developed economy , and advanced technological infrastructure relative to other less industrialized nations. Most commonly, the criteria for evaluating the degree of economic development are the gross domestic product (GDP), gross national product (GNP), the per capita income , level of industrialization, amount of widespread infrastructure and general standard of living. Which criteria are to be used and which countries can be classified as being developed are subjects of debate. Different definitions of developed countries are provided by
1620-478: Is a common effect of urbanization. Precipitation from rooftops, roads, parking lots and sidewalks flows to storm drains , instead of percolating into groundwater . The contaminated stormwater in the drains is typically untreated and flows to nearby streams, rivers or coastal bays. Eutrophication in water bodies is another effect large populations in cities have on the environment. When rain occurs in these large cities, it filters CO 2 and other pollutants in
1701-498: Is an ongoing process that is hard to define. The first industrialized country was the United Kingdom , followed by Belgium . Later it spread further to Germany , United States , France and other Western European countries. According to some economists such as Jeffrey Sachs , however, the current divide between the developed and developing world is largely a phenomenon of the 20th century. Mathis Wackernagel calls

Furthermore, urbanization improves environmental eminence through superior facilities and standards in urban areas as compared to rural areas. Lastly, urbanization curbs pollution emissions by increasing innovations. In his 2009 book Whole Earth Discipline , Stewart Brand argues that the effects of urbanization are primarily positive for the environment. First,
1863-476: Is happening in the cities of the largest developing countries, may be regarded as an attempt to balance these harmful aspects of urban life while still allowing access to the large extent of shared resources. In cities, money, services, wealth and opportunities are centralized. Many rural inhabitants come to the city to seek their fortune and alter their social position. Businesses, which provide jobs and exchange capital, are more concentrated in urban areas. Whether
1944-418: Is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth . Urbanization refers to the proportion of the total national population living in areas classified as urban, whereas urban growth strictly refers to

Urban geographers have shown that there exists a large productivity gain due to locating in dense agglomerations. It is thus possible that agents locate in cities in order to benefit from these agglomeration effects. The dominant conurbation (s) of a country can get more benefits from
2106-430: The 2011 Thailand floods and 2007 Jakarta flood . Urban areas are also far more prone to violence , drugs , and other urban social problems. In the United States, industrialization of agriculture has negatively affected the economy of small and middle-sized farms and strongly reduced the size of the rural labour market. – Madhura Swaminathan, economist at Kolkata's Indian Statistical Institute Particularly in
2187-475: The Human Development Index (HDI), which combines an economic measure, national income, with other measures, indices for life expectancy and education has become prominent. This criterion would define developed countries as those with a very high (HDI) rating. The index, however, does not take into account several factors, such as the net wealth per capita or the relative quality of goods in
2268-476: The IMF . Economic criteria have tended to dominate discussions. One such criterion is the income per capita; countries with the high gross domestic product (GDP) per capita would thus be described as developed countries. Another economic criterion is industrialisation ; countries in which the tertiary and quaternary sectors of industry dominate would thus be described as developed. More recently, another measure,

In 2023 , 40 countries fit all four criteria, while an additional 19 countries fit three out of four. Developed countries have generally more advanced post-industrial economies, meaning the service sector provides more wealth than
2430-660: The Overseas Development Institute have proposed policies that encourage labour-intensive to make use of the migration of less skilled workers. One problem these migrant workers are involved with is the growth of slums . In many cases, the rural-urban unskilled migrant workers are attracted by economic opportunities in cities. Unfortunately, they cannot find a job and or pay for houses in urban areas and have to live in slums. Urban problems, along with developments in their facilities, are also fuelling suburb development trends in less developed nations, though
2511-513: The absolute number of people living in those areas. It is predicted that by 2050 about 64% of the developing world and 86% of the developed world will be urbanized. This is predicted to generate artificial scarcities of land, lack of drinking water, playgrounds and so on for most urban dwellers. The predicted urban population growth is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia . Notably,

2592-502: The city centre for the working class . Urbanization rapidly spread across the Western world and, since the 1950s, it has begun to take hold in the developing world as well. At the turn of the 20th century, just 15% of the world population lived in cities. According to the UN , the year 2007 witnessed the turning point when more than 50% of the world population were living in cities, for

They are contrasted with developing countries , which are in the process of industrialisation or are pre-industrial and almost entirely agrarian , some of which might fall into the category of Least Developed Countries . As of 2023 , advanced economies comprise 57.3% of global GDP based on nominal values and 41.1% of global GDP based on purchasing-power parity (PPP) according to
2754-408: The sociological process of rationalization . Urbanization can be seen as a specific condition at a set time (e.g. the proportion of total population or area in cities or towns), or as an increase in that condition over time. Therefore, urbanization can be quantified either in terms of the level of urban development relative to the overall population, or as the rate at which the urban proportion of

For example, Eric Hobsbawm 's book The age of revolution: 1789–1848 (published 1962 and 2005) chapter 11, stated "Urban development in our period was a gigantic process of class segregation, which pushed the new labouring poor into great morasses of misery outside the centres of government, business, and

This helps to lessen the harmful effects of greenhouse gases. But it also makes the ocean more acidic. A drop in pH the prevents the proper formation of calcium carbonate, which sea creatures need to build or keep shells or skeletons. This is especially true for many species of molluscs and coral. However, some species have been able to thrive in
2997-486: The HDI accounts for more than income or productivity. Unlike GDP per capita or per capita income, the HDI takes into account how income is turned "into education and health opportunities and therefore into higher levels of human development." Since 1990, Norway (2001–2006, 2009–2019), Japan (1990–1991 and 1993), Canada (1992 and 1994–2000) and Iceland (2007–2008) have had the highest HDI score. The following countries in

In the long term, urbanization is expected to significantly impact the quality of life in negative ways. Urbanization is relevant to a range of disciplines, including urban planning , geography , sociology , architecture , economics , education , statistics , and public health . The phenomenon has been closely linked to globalization , modernization , industrialization , marketization , administrative/institutional power , and

In addition, children with croup living in urban areas have higher hazard ratios for asthma than similar children living in rural areas. Researchers suggest that this difference in hazard ratios is due to the higher levels of air pollution and exposure to environmental allergens found in urban areas. Exposure to elevated levels of ambient air pollutants such as nitrogen dioxide (NO 2 ), carbon monoxide (CO), and particulate matter with

In children, urbanization is associated with a lower risk of under-nutrition but a higher risk of being overweight . Urbanization has also been linked to the spread of communicable diseases, which can spread more rapidly in the favourable environment with more people living in a smaller area. Such diseases can be respiratory infections and gastrointestinal infections. Other infections could be infections, which need

Overgrowth of algal blooms makes water worse overall and disrupts the natural balance of aquatic ecosystems. Furthermore, as algal blooms die, CO 2 is produced. This makes the ocean more acidic, a process called acidification. The ocean's surface can absorb CO 2 from
3726-408: The air onto the ground. These chemicals are washed directly into rivers, streams, and oceans, making water worse and damaging ecosystems in them. Eutrophication is a process which causes low levels of oxygen in water and algal blooms that may harm aquatic life. Harmful algal blooms make dangerous toxins. They live best in nitrogen- and phosphorus-rich places which include the oceans contaminated by
3807-457: The binary labeling of countries as "neither descriptive nor explanatory. It is merely a thoughtless and destructive endorsement of GDP fetish. In reality, there are not two types of countries, but over 200 countries, all faced with the same laws of nature, yet each with unique features." A 2021 analysis proposes the term emerged to describe markets, economies, or countries that have graduated from emerging market status, but have not yet reached
3888-450: The birth rate of new urban dwellers falls immediately to replacement rate and keeps falling, reducing environmental stresses caused by population growth. Secondly, emigration from rural areas reduces destructive subsistence farming techniques, such as improperly implemented slash and burn agriculture. Alex Steffen also speaks of the environmental benefits of increasing the urbanization level in "Carbon Zero: Imagining Cities that can save

Greater Seoul is one conurbation that dominates South Korea. It is home to 50% of the entire national population. Though Greater Busan-Ulsan (15%, 8 million) and Greater Osaka (14%, 18 million) dominate their respective countries, their populations are moving to their even more dominant rivals, Seoul and Tokyo respectively. As cities develop, costs will skyrocket. This often takes
4050-798: The combination of ill-health and poverty entrenches disadvantage over time." Many of the urban poor have difficulty accessing health services due to their inability to pay for them; so they resort to less qualified and unregulated providers. While urbanization is associated with improvements in public hygiene , sanitation and access to health care , it also entails changes in occupational, dietary , and exercise patterns. It can have mixed effects on health patterns, alleviating some problems, and accentuating others. Traditionally, rural populations have tended to eat plant-based diets rich in grains, fruits and vegetables, and with low fat content. However, rural people migrating to urban areas often shift towards diets that rely more on processed foods characterized by
4131-741: The connection of areas and allow for easier movement around urbanized regions. Depending on the various factors, such as level of urbanization, both increases or decreases in "species richness" can be seen. This means that urbanization may be detrimental to one species but also help facilitate the growth of others. In instances of housing and building development, many times vegetation is completely removed immediately in order to make it easier and less expensive for construction to occur, thereby obliterating any native species in that area. Habitat fragmentation can filter species with limited dispersal capacity. For example, aquatic insects are found to have lower species richness in urban landscapes. The more urbanized

#17327935377494212-550: The developing world, conflict over land rights due to the effects of globalization has led to less politically powerful groups, such as farmers, losing or forfeiting their land, resulting in obligatory migration into cities. In China, where land acquisition measures are forceful, there has been far more extensive and rapid urbanization (54%) than in India (36%), where peasants form militant groups (e.g. Naxalites ) to oppose such efforts. Obligatory and unplanned migration often results in

Rapid urbanization has led to increased mortality from non-communicable diseases associated with lifestyle, including cancer and heart disease . Differences in mortality from contagious diseases vary depending on the particular disease and location. Urban health levels are on average better in comparison to rural areas. However, residents in poor urban areas such as slums and informal settlements suffer "disproportionately from disease, injury, premature death, and
4374-509: The face of increased urbanization is at the centre of international policy in Sustainable Development Goal 11 "Sustainable cities and communities." Urbanization is not merely a modern phenomenon, but a rapid and historic transformation of human social roots on a global scale, whereby predominantly rural culture is being rapidly replaced by predominantly urban culture . The first major change in settlement patterns

Yale University in June 2016 published urbanization data from the time period 3700 BC to 2000 AD, the data was used to make a video showing the development of cities on the world during the time period. The origins and spread of urban centres around the world were also mapped by archaeologists . Urbanization occurs either organically or planned as
4536-489: The growing population of urban regions, according to UN experts, will strain basic sanitation systems and health care, and potentially cause a humanitarian and environmental disaster. Urban heat islands have become a growing concern over the years. An urban heat island is formed when industrial areas absorb and retain heat. Much of the solar energy reaching rural areas is used to evaporate water from plants and soil. In cities, there are less vegetation and exposed soil. Most of

In many developing countries where economies are growing, the growth is often random and based on a small number of industries. Youths in these nations lack access to financial services and business advisory services, cannot get credit to start a business, and have no entrepreneurial skills. Therefore, they cannot seize opportunities in these industries. Making sure adolescents have access to excellent schools and infrastructure to work in such industries and improve schools

This is probably caused by the south-west wind which carries coal smoke and other pollutants down, making the western edges of towns better than the eastern ones. Similar problems now affect less developed countries, as rapid development of cities makes inequality worse. The drive to grow quickly and be efficient can lead to less fair urban development.

This creates a gender-related transformation where women are engaged in paid employment and have access to education. This may cause fertility to decline. However, women are sometimes still at a disadvantage due to their unequal position in the labour market, their inability to secure assets independently from male relatives and exposure to violence. People in cities are more productive than in rural areas. An important question

Urbanization creates enormous social, economic and environmental challenges, which provide an opportunity for sustainability with the "potential to use resources much less or more efficiently, to create more sustainable land use and to protect the biodiversity of natural ecosystems." However, current urbanization trends have shown that massive urbanization has led to unsustainable ways of living. Developing urban resilience and urban sustainability in

Cities offer a larger variety of services, including specialist services not found in rural areas. These services require workers, resulting in more numerous and varied job opportunities. Elderly people may be forced to move to cities where there are doctors and hospitals that can cater to their health needs. Varied and high-quality educational opportunities are another factor in urban migration, as well as

Many people move into cities for economic opportunities, but this does not fully explain the very high recent urbanization rates in places like China and India. Rural flight is a contributing factor to urbanization. In rural areas, often on small family farms or collective farms in villages, it has historically been difficult to access manufactured goods, though
5751-652: The sun's energy is instead absorbed by buildings and asphalt; leading to higher surface temperatures. Vehicles, factories, and heating and cooling units in factories and homes release even more heat. As a result, cities are often 1 to 3 °C (1.8 to 5.4 °F) warmer than other areas near them. Urban heat islands also make the soil drier and absorb less carbon dioxide from emissions.
