226-638: 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,

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

452-450: A 5,100-foot (1,600 m) runway. Perris has drawn a crowd of skydivers , amateur and professional, to Perris Valley Skydiving. The area's sudden fame gave Perris the nickname: "the skydiving capital of America". On April 22, 1992, a de Havilland Twin Otter crashed during takeoff at Perris Valley after an engine lost power. The National Transportation Safety Board determined that the accident

565-404: A Pomona County and one for a San Jacinto County. None of the proposals were adopted until a measure to create Riverside County was signed by Governor Henry H. Markham on March 11, 1893. The new county was created from parts of San Bernardino County and San Diego County . On May 2, 1893, seventy percent of voters approved the formation of Riverside County. Voters chose the city of Riverside as

678-402: 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 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

791-477: 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

904-403: 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 a fixed address. People with second homes, because they are working in another part of

1017-499: 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

1130-428: 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 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

1243-534: A land title dispute at Pinacate , most of its citizens moved two miles north on the railroad and established Perris in 1885. The city is named in honor of Fred T.

1356-500: 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

1469-469: 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

1582-433: 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

1695-423: 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 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

1808-572: A population of 2,189,641. The racial makeup of Riverside County was 1,335,147 (61.0%) White (40.7% Non-Hispanic White), 140,543 (6.4%) African American , 23,710 (1.1%) Native American , 130,468 (6.0%) Asian (2.3% Filipino, 0.8% Chinese, 0.7% Vietnamese, 0.6% Korean, 0.5% Indian, 0.2% Japanese, 0.1% Cambodian, 0.1% Laotian, 0.1% Pakistani), 6,874 (0.3%) Pacific Islander , 448,235 (20.5%) from other races , and 104,664 (4.8%) from two or more races.

The Perris Depot is included in the Library of Congress’ Historic American Buildings Survey . Due to

2034-460: 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

2147-439: 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 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

2260-678: 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

Some extend into neighboring counties: The 2010 United States Census reported that Riverside County had

2712-453: 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

2825-467: 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 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

2938-402: 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 the only method of collecting national demographic data and are now part of a larger system of different surveys. Although population estimates remain an important function of a census, including exactly

Recent UN guidelines provide recommendations on enumerating such complex households. In 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.

For instance, when reporting data from

7119-454: 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.

For this reason, international documents refer to censuses of population and housing. Normally

8814-483: The essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years.

Another method is simply to release no data at all, except very large scale data directly to

9379-443: 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.

A census can be contrasted with sampling in which information

9492-785: 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.
