94-523: The Population Estimates Program ( PEP ) is a program of the U.S. Census Bureau that publishes annual population estimates and estimates of birth, death, and international migration rates for people in the United States. In addition to publishing those aggregate estimates for the entire country, the program also publishes those yearly estimates by age, sex, race, and Hispanic origin at the national, state, county and city and town level. By doing so,

188-660: A base-10 positional system. On May 25, 1577, King Philip II of Spain ordered by royal cédula the preparation of a general description of Spain's holdings in the Indies. Instructions and a questionnaire, issued in 1577 by the Office of the Cronista Mayor, were distributed to local officials in the Viceroyalties of New Spain and Peru to direct the gathering of information. The questionnaire, composed of fifty items,

282-544: A census for tax purposes, which was partially responsible for the development of the Zealot movement and several failed rebellions against Rome ultimately ending in the Jewish Diaspora . The Gospel of Luke makes reference to Quirinius' census in relation to the birth of Jesus ; based on variant readings of this passage, a minority of biblical scholars, including N. T. Wright , speculate that this passage refers to

376-408: A sampling frame such as an address register. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling . Similarly, stratification requires knowledge of the relative sizes of different population strata, which can be derived from census enumerations. In some countries, the census provides the official counts used to apportion

470-412: A sampling frame to count the population. This is the only way to be sure that everyone has been included, as otherwise those not responding would not be followed up on and individuals could be missed. The fundamental premise of a census is that the population is not known, and a new estimate is to be made by the analysis of primary data. The use of a sampling frame is counterintuitive as it suggests that

564-480: A "permanent" address, which might be a family home for students or long-term migrants. A precise definition of residence is needed, to decide whether visitors to a country should be included in the population count. This is becoming more important as students travel abroad for education for a period of several years. Other groups causing problems with enumeration are newborn babies, refugees, people away on holiday, people moving home around census day, and people without

658-477: A clan or tribe, or by a juridical person such as a corporation, cooperative, or government agency. The holding's land may consist of one or more parcels, located in one or more separate areas or one or more territorial or administrative divisions, providing the parcels share the same production means, such as labor, farm buildings, machinery or draught animals. Historical censuses used crude enumeration assuming absolute accuracy. Modern approaches take into account

752-490: A country." "In a census of agriculture, data are collected at the holding level." The word is of Latin origin: during the Roman Republic , the census was a list of all adult males fit for military service. The modern census is essential to international comparisons of any type of statistics, and censuses collect data on many attributes of a population, not just the number of individuals. Censuses typically began as

846-415: A family home during vacations, or children whose parents have separated who effectively have two family homes. Census enumeration has always been based on finding people where they live, as there is no systematic alternative: any list used to find people is likely to be derived from census activities in the first place. Recent UN guidelines provide recommendations on enumerating such complex households. In

940-510: A fishing analogy can be found in "Trout, Catfish and Roach..." which won an award from the Royal Statistical Society for excellence in official statistics in 2011. Triple system enumeration has been proposed as an improvement as it would allow evaluation of the statistical dependence of pairs of sources. However, as the matching process is the most difficult aspect of census estimation this has never been implemented for

1034-414: A fixed address. People with second homes, because they are working in another part of the country or have a holiday cottage, are difficult to fix at a particular address; this sometimes causes double counting or houses being mistakenly identified as vacant. Another problem is where people use a different address at different times e.g. students living at their place of education in term time but returning to

1128-500: A large city, it might be appropriate to give the average income for black males aged between 50 and 60. However, doing this for a town that only has two black males in this age group would be a breach of privacy because either of those persons, knowing his own income and the reported average, could determine the other man's income. Typically, census data are processed to obscure such individual information. Some agencies do this by intentionally introducing small statistical errors to prevent

1222-448: A ledger. Beginning in 1970 information was gathered via mailed forms. To reduce paper usage, reduce payroll expense and acquire the most comprehensive list of addresses ever compiled, 500,000 handheld computers (HHCs) (specifically designed, single-purpose devices) were used for the first time in 2009 during the address canvassing portion of the 2010 Decennial Census Project. Projected savings were estimated to be over $ 1 billion. The HHC

1316-469: A national enumeration. It would also be difficult to identify three different sources that were sufficiently different to make the triple system effort worthwhile. The DSE approach has another weakness in that it assumes there is no person counted twice (over count). In de facto residence definitions this would not be a problem but in de jure definitions individuals risk being recorded on more than one form leading to double counting. A particular problem here

1410-511: A northern and southern half called "divisions". In the following decades, several other systems were used, until the current one was introduced in 1910. This system has seen only minor changes: New Mexico and Arizona were both added to the Mountain division upon statehood in 1912, the North region was divided into a Northeast and a North Central region in 1940, Alaska and Hawaii were both added to

1504-433: A population and housing census – numbers of people, their distribution, their living conditions and other key data – is critical for development." This is because this type of data is essential for policymakers so that they know where to invest. Many countries have outdated or inaccurate data about their populations and thus have difficulty in addressing the needs of the population. The UNFPA said: "The unique advantage of

1598-458: A real-time estimate in U.S. and World Population Clock. Only peoples whose live in the 50 states and within the District of Columbia are included in the estimation. The United States Census Bureau is committed to confidentiality and guarantees non-disclosure of any addresses or personal information related to individuals or establishments. Title 13 of the U.S. Code establishes penalties for

1692-460: A realist approach to measurement, acknowledging that under any definition of residence there is a true value of the population but this can never be measured with complete accuracy. An important aspect of the census process is to evaluate the quality of the data. Many countries use a post-enumeration survey to adjust the raw census counts. This works similarly to capture-recapture estimation for animal populations. Among census experts, this method

1786-704: A separate registration conducted during the reign of Herod the Great , several years before Quirinius' census. The 15-year indiction cycle established by Diocletian in AD   297 was based on quindecennial censuses and formed the basis for dating in late antiquity and under the Byzantine Empire . In the Middle Ages , the Caliphate began conducting regular censuses soon after its formation, beginning with

1880-496: A zero and uses the term " decennial " to describe the operation. Between censuses, the Census Bureau makes population estimates and projections. In addition, census data directly affects how more than $ 400 billion per year in federal and state funding is allocated to communities for neighborhood improvements, public health , education, transportation and more. The Census Bureau is mandated with fulfilling these obligations:

1974-482: Is at stake, the census also runs the risk of being politicized." Such political tensions highlight the complexity of identity and classification ; some argue that unclear results from the population data "is due to distortions brought about by political pressures." One frequently used example includes ambiguous ethnic counts, which often involves underenumeration and/or undercounting of minority populations. Ideas about race, ethnicity and identity have also evolved in

2068-453: Is called dual system enumeration (DSE). A sample of households is visited by interviewers who record the details of the household as of census day. These data are then matched to census records, and the number of people missed can be estimated by considering the number of people who are included in one count but not the other. This allows adjustments to the count for non-response, varying between different demographic groups. An explanation using

2162-534: Is conducting the U.S. census every ten years, which allocates the seats of the U.S. House of Representatives to the states based on their population. The bureau's various censuses and surveys help allocate over $ 675 billion in federal funds every year and it assists states, local communities, and businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, hospitals, transportation infrastructure, and police and fire departments. In addition to

2256-401: Is important in considering individuals who have multiple or temporary addresses. Every person should be identified uniquely as a resident in one place; but the place where they happen to be on Census Day, their de facto residence , may not be the best place to count them. Where an individual uses services may be more useful, and this is at their usual residence. An individual may be recorded at

2350-469: Is interested; researchers in particular have an interest in the role of Census Field Officers (CFO) and their assistants. Data can be represented visually or analysed in complex statistical models, to show the difference between certain areas, or to understand the association between different personal characteristics. Census data offer a unique insight into small areas and small demographic groups which sample data would be unable to capture with precision. In

2444-714: Is named after the counting of the Israelite population according to the house of the Fathers after the exodus from Egypt. A second census was taken while the Israelites were camped in the " plains of Moab ". King David performed a census that produced disastrous results. His son, King Solomon , had all of the foreigners in Israel counted. One of the world's earliest preserved censuses was held in China in AD   2 during

2538-538: Is not known if there are any residents or how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, an enumerator calls, or administrative records for the dwelling are accessed. As a preliminary to the dispatch of forms, census workers will check for any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, this can be out of date and some dwellings may contain several independent households. A particular problem

2632-553: Is pervasive. The territories are not included, but the District of Columbia is. Regional divisions used by the United States Census Bureau: The first census was collected in 1790 and published in 1791. It was 56 pages and cost $ 44,377.28. The current system was introduced for the 1910 census, but other ways of grouping states were used historically by the Census Bureau. The first of these

2726-423: Is still conducted in a similar way to the post-enumeration survey employed in a traditional census. Other countries that have a population register use this as a basis for all the census statistics needed by users. This is most common among Nordic countries but requires many distinct registers to be combined, including population, housing, employment, and education. These registers are then combined and brought up to

2820-415: Is students who often have a term time and family address. Several countries have used a system known as short form/long form. This is a sampling strategy that randomly chooses a proportion of people to send a more detailed questionnaire to (the long form). Everyone receives the short-form questions. This means more data are collected, but without imposing a burden on the whole population. This also reduces

2914-491: Is typically collected about the household structure and the housing. For this reason, international documents refer to censuses of population and housing. Normally the census response is made by a household, indicating details of individuals resident there. An important aspect of census enumerations is determining which individuals can be counted and which cannot be counted. Broadly, three definitions can be used: de facto residence; de jure residence; and permanent residence. This

3008-416: Is what is termed " communal establishments ", a category that includes student residences, religious orders, homes for the elderly, people in prisons, etc. As these are not easily enumerated by a single householder, they are often treated differently and visited by special teams of census workers to ensure they are classified appropriately. Individuals are normally counted within households , and information

3666-692: The nomarch , "whence he gained his living". Under the Ptolemies and the Romans several censuses were conducted in Egypt by government officials. There are several accounts of ancient Greek city states carrying out censuses. Censuses are mentioned several times in the Biblical narrative. God commands a per capita tax to be paid with the census for the upkeep of the Tabernacle . The Book of Numbers

3760-437: The population size is already known. However, a census is also used to collect attribute data on the individuals in the nation, not only to assess population size. This process of sampling marks the difference between a historical census, which was a house-to-house process or the product of an imperial decree, and the modern statistical project. The sampling frame used by a census is almost always an address register. Thus, it

3854-412: The 19th and 20th centuries collected paper documents which had to be collated by hand, so the statistical information obtained was quite basic. The government that owned the data could publish statistics on the state of the nation. The results were used to measure changes in the population and apportion representation. Population estimates could be compared to those of other countries. By the beginning of

3948-437: The 20th century, censuses were recording households and some indications of their employment. In some countries, census archives are released for public examination after many decades, allowing genealogists to track the ancestry of interested people. Archives provide a substantial historical record which may challenge established views. Information such as job titles and arrangements for the destitute and sick may also shed light on

During World War II , the United States Census Bureau assisted the government's Japanese American internment efforts by providing confidential neighborhood information on Japanese-Americans . The bureau's role

4324-458: The Census Bureau stopped releasing new data via American FactFinder, which was decommissioned in March 2020 after 20 years of being the agency's primary tool for data dissemination. The new platform is data.census.gov. Throughout the decade between censuses, the bureau conducts surveys to produce a general view and comprehensive study of the United States' social and economic conditions. Staff from

A network of professional field representatives gathers information from a sample of households, responding to questions about employment, consumer expenditures, health, housing, and other topics. Surveys conducted between decades: The Census Bureau also collects information on behalf of survey sponsors. These sponsors include

4512-501: The HHC. Since the units were updated nightly with important changes and updates, operator implementation of proper procedure was imperative. Census Bureau stays current by conducting research studies to improve the work that they do. Census researchers explore topics about survey innovations, participation, and data accuracy, such as undercount, overcount, the use of technologies, multilingual research, and ways to reduce costs. In addition,

Seventy-two years was picked because usually by 72 years since the census is taken, most participants would be deceased. Despite these guarantees of confidentiality, the Census Bureau has some history of disclosures to other government agencies. In 1918,

The National Processing Center is in Jeffersonville, Indiana . Additional temporary processing facilities facilitate

5358-417: The burden on the statistical office. Indeed, in the UK until 2001 all residents were required to fill in the whole form but only a 10% sample was coded and analysed in detail. New technology means that all data are now scanned and processed. During the 2011 Canadian census there was controversy about the cessation of the mandatory long-form census; the head of Statistics Canada , Munir Sheikh , resigned upon

5452-438: The census is also an important tool for identifying forms of social, demographic or economic exclusions, such as inequalities relating to race, ethics, and religion as well as disadvantaged groups such as those with disabilities and the poor. An accurate census can empower local communities by providing them with the necessary information to participate in local decision-making and ensuring they are represented. The importance of

5546-536: The census is that it represents the entire statistical universe, down to the smallest geographical units, of a country or region. Planners need this information for all kinds of development work, including: assessing demographic trends; analysing socio-economic conditions; designing evidence-based poverty-reduction strategies; monitoring and evaluating the effectiveness of policies; and tracking progress toward national and internationally agreed development goals." In addition to making policymakers aware of population issues,

5640-443: The census of agriculture , data is collected at the agricultural holding unit. An agricultural holding is an economic unit of agricultural production under single management comprising all livestock kept and all land used wholly or partly for agricultural production purposes, without regard to title, legal form, or size. Single management may be exercised by an individual or household, jointly by two or more individuals or households, by

5734-474: The census of agriculture for development is that it gives a snapshot of the structure of the agricultural sector in a country and, when compared with previous censuses, provides an opportunity to identify trends and structural transformations of the sector, and points towards areas for policy intervention. Census data are used as a benchmark for current statistics and their value is increased when they are employed together with other data sources. Early censuses in

5828-563: The census of agriculture, users need census data to: Although the census provides useful statistical information about a population, the availability of this information could sometimes lead to abuses, political or otherwise, by the linking of individuals' identities to anonymous census data. This is particularly important when individuals' census responses are made available in microdata form, but even aggregate-level data can result in privacy breaches when dealing with small areas and/or rare subpopulations. For instance, when reporting data from

5922-515: The census was taken by marshals of the judicial districts . The Census Act of 1840 established a central office which became known as the Census Office. Several acts followed that revised and authorized new censuses, typically at the 10-year intervals. In 1902, the temporary Census Office was moved under the Department of Interior , and in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor . The department

6016-575: The central government. Differing release strategies of governments have led to an international project ( IPUMS ) to co-ordinate access to microdata and corresponding metadata. Such projects such as SDMX also promote standardising metadata, so that best use can be made of the minimal data available. Censuses in Egypt first appeared in the late Middle Kingdom and developed in the New Kingdom Pharaoh Amasis , according to Herodotus , required every Egyptian to declare annually to

The Census Bureau also conducts surveys on behalf of various federal government and local government agencies on topics such as employment, crime, health, consumer expenditures , and housing. Within the bureau, these are known as "demographic surveys" and are conducted perpetually between and during decennial (10-year) population counts. The Census Bureau also conducts economic surveys of manufacturing, retail, service, and other establishments and of domestic governments. Between 1790 and 1840,

6204-520: The combination of data from registers, surveys and other sources. Censuses have evolved in their use of technology: censuses in 2010 used many new types of computing. In Brazil, handheld devices were used by enumerators to locate residences on the ground. In many countries, census returns could be made via the Internet as well as in paper form. DSE is facilitated by computer matching techniques that can be automated, such as propensity score matching . In

6298-550: The decennial census, the Census Bureau continually conducts over 130 surveys and programs a year, including the American Community Survey , the U.S. Economic Census , and the Current Population Survey . The U.S. Economic Census occurs every five years and reports on American Business and the American economy in order to plan business decisions. Furthermore, economic and foreign trade indicators released by

6392-500: The decennial census, which employs more than a million people. The cost of the 2000 census was $ 4.5 billion. During the years just prior to the decennial census, parallel census offices, known as "Regional Census Centers" are opened in the field office cities. The decennial operations are carried out from these facilities. The Regional Census Centers oversee the openings and closings of smaller "Area Census Offices" within their collection jurisdictions. In 2020, Regional Census Centers oversaw

6486-529: The disclosure of this information. All census employees must sign an affidavit of non-disclosure prior to employment. This non-disclosure states "I will not disclose any information contained in the schedules, lists, or statements obtained for or prepared by the Census Bureau to any person or persons either during or after employment." The punishment for breaking the non-disclosure is a fine up to $ 250,000 or 5 years in prison. The bureau cannot share responses, addresses or personal information with anyone, including

6580-658: The federal government typically contain data produced by the Census Bureau. Article One of the United States Constitution (section II) directs the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the House of Representatives and, by extension, in the Electoral College . The Census Bureau now conducts a full population count every ten years in years ending with

6674-548: The federal government's decision to do so. The use of alternative enumeration strategies is increasing but these are not as simple as many people assume and are only used in developed countries. The Netherlands has been most advanced in adopting a census using administrative data . This allows a simulated census to be conducted by linking several different administrative databases at an agreed time. Data can be matched, and an overall enumeration established allowing for discrepancies between different data sources. A validation survey

6768-423: The form of conditional distributions ( histograms ) can be derived interactively from the estimated mixture model without any further access to the original database. As the final product does not contain any protected microdata, the model-based interactive software can be distributed without any confidentiality concerns. Another method is simply to release no data at all, except very large scale data directly to

6862-792: The historical structure of society. Political considerations influence the census in many countries. In Canada in 2010 for example, the government under the leadership of Stephen Harper abolished the mandatory long-form census. This abolition was a response to protests from some Canadians who resented the personal questions. The long-form census was reinstated by the Justin Trudeau government in 2016. As governments assumed responsibility for schooling and welfare, large government research departments made extensive use of census data. Population projections could be made, to help plan for provision in local government and regions. Central government could also use census data to allocate funding. Even in

6956-466: The identification of individuals in marginal populations; others swap variables for similar respondents. Whatever is done to reduce the privacy risk, new improved electronic analysis of data can threaten to reveal sensitive individual information. This is known as statistical disclosure control . Another possibility is to present survey results by means of statistical models in the form of a multivariate distribution mixture. The statistical information in

7050-511: The internet. It is also possible that the hidden nature of an administrative census means that users are not engaged with the importance of contributing their data to official statistics. Alternatively, population estimations may be carried out remotely with geographic information system (GIS) and remote sensing technologies. According to the United Nations Population Fund (UNFPA), "The information generated by

7144-524: The mid 20th century, census data was only directly accessible to large government departments. However, computers meant that tabulations could be used directly by university researchers, large businesses and local government offices. They could use the detail of the data to answer new questions and add to local and specialist knowledge. Nowadays, census data are published in a wide variety of formats to be accessible to business, all levels of government, media, students and teachers, charities, and any citizen who

7238-535: The net number of international migrants. Estimates for the number of US resident births and deaths are based on data on birth certificates and death certificates provided by the National Center for Health Statistics (NCHS). Estimates for net international migration are based on information from the American Community Survey, NCHS, and the previous census. United States Census Bureau The United States Census Bureau ( USCB ), officially

7332-403: The number of elected representatives to regions (sometimes controversially – e.g., Utah v. Evans ). In many cases, a carefully chosen random sample can provide more accurate information than attempts to get a population census. A census is often construed as the opposite of a sample as it intends to count everyone in a population, rather than a fraction. However, population censuses do rely on

The Domesday Book was undertaken in AD   1086 by William I of England so that he could properly tax the land he had recently conquered. In 1183, a census was taken of the crusader Kingdom of Jerusalem , to ascertain the number of men and amount of money that could possibly be raised against an invasion by Saladin , sultan of Egypt and Syria .

Although population estimates remain an important function of a census, including exactly the geographic distribution of the population or the agricultural population, statistics can be produced about combinations of attributes, e.g., education by age and sex in different regions. Current administrative data systems allow for other approaches to enumeration with

7614-638: The operation of 248 Area Census Offices, The estimated cost of the 2010 census is $ 14.7 billion. On January 1, 2013, the Census Bureau consolidated its twelve regional offices into six. Increasing costs of data collection, changes in survey management tools such as laptops and the increasing use of multi-modal surveys (i.e. internet, telephone, and in-person) led the Bureau to consolidate. The six regional offices that closed were Boston, Charlotte, Dallas, Detroit, Kansas City and Seattle. The remaining regional offices are New York City, Philadelphia, Chicago, Atlanta, Denver, and Los Angeles. The Census Bureau also runs

7708-445: The populace's private information. Enumerators (information gatherers) that had operational problems with the device understandably made negative reports. During the 2009 Senate confirmation hearings for Robert Groves , President Obama's Census Director appointee, there was much mention of problems but very little criticism of the units. In rural areas, the sparsity of cell phone towers caused problems with data transmission to and from

7802-428: The problems of overcount and undercount and the coherence of census enumerations with other official sources of data. For instance, during the 2020 U.S. Census, the Census Bureau counted people primarily by collecting answers sent by mail, on the internet, over the phone, or using shared information through proxies. These methods accounted for 95.5 percent of all occupied housing units in the United States. This reflects

The census played a crucial role in the administration of the Roman government, as it was used to determine the class a citizen belonged to for both military and tax purposes. Beginning in the middle republic, it

7990-443: The same level of detail but raise concerns about privacy and the possibility of biasing estimates. A census can be contrasted with sampling in which information is obtained only from a subset of a population; typically, main population estimates are updated by such intercensal estimates . Modern census data are commonly used for research, business marketing , and planning, and as a baseline for designing sample surveys by providing

8084-534: The standard of a statistical register by comparing the data from different sources and ensuring the quality is sufficient for official statistics to be produced. A recent innovation is the French instigation of a rolling census program with different regions enumerated each year so that the whole country is completely enumerated every 5 to 10 years. In Europe, in connection with the 2010 census round, many countries adopted alternative census methodologies, often based on

8178-443: Was abandoned, with the contract being sold to Brazil. The online response has some advantages, but one of the functions of the census is to make sure everyone is counted accurately. A system that allowed people to enter their address without verification would be open to abuse. Therefore, households have to be verified on the ground, typically by an enumerator visit or post out . Paper forms are still necessary for those without access to

8272-552: Was denied for decades but was finally proven in 2007. United States census data are valuable for the country's political parties; Democrats and Republicans are highly interested in knowing the accurate number of persons in their respective districts. These insights are often linked to financial and economic strategies that are central to federal, state and city investments for locations of particular populations. Such apportionments are designed to distribute political power across neutral spatial allocations; however, "because so much

8366-533: Was designed to elicit basic information about the nature of the land and the life of its peoples. The replies, known as " relaciones geográficas ", were written between 1579 and 1585 and were returned to the Cronista Mayor in Spain by the Council of the Indies. The earliest estimate of the world population was made by Giovanni Battista Riccioli in 1661; the next by Johann Peter Süssmilch in 1741, revised in 1762;

8460-511: Was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their subordinate role in the department. An act in 1920 changed the date and authorized manufacturing censuses every two years and agriculture censuses every 10 years. In 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 census . In 1954, various acts were codified into Title 13 of

8554-721: Was introduced after the 1850 census by statistician and later census superintendent J. D. B. De Bow . He published a compendium where the states and territories were grouped into five "great division", namely the Middle, New England, the Northwestern, the Southern, and the Southwestern great divisions. Unsatisfied with this system, De Bow devised another one four years later, with states and territories grouped into an Eastern, Interior, and Western "great section", each divided into

8648-414: Was manufactured by Harris Corporation , an established Department of Defense contractor, via a controversial contract with the Department of Commerce . Secured access via a fingerprint swipe guaranteed only the verified user could access the unit. A GPS capacity was integral to the daily address management and the transfer of gathered information. Of major importance was the security and integrity of

8742-524: Was undertaken in 1328, mostly for fiscal purposes. It estimated the French population at 16 to 17 million. In the 15th century, the Inca Empire had a unique way to record census information. The Incas did not have any written language but recorded information collected during censuses and other numeric information as well as non-numeric data on quipus , strings from llama or alpaca hair or cotton cords with numeric and other values encoded by knots in

8836-493: Was usually carried out every five years. It provided a register of citizens and their property from which their duties and privileges could be listed. It is said to have been instituted by the Roman king Servius Tullius in the 6th century BC, at which time the number of arms-bearing citizens was supposedly counted at around 80,000.
