In the 1970s, tension grew between population control advocates and women's health activists who advanced women's reproductive rights as part of a human rights -based approach. Growing opposition to the narrow population control focus led to a significant change in population control policies in

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

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:
477-913: Is also known therefore as a gamodeme. This also implies that all members belong to the same species. If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic. Under this state, allele ( gamete ) frequencies can be converted to genotype ( zygote ) frequencies by expanding an appropriate quadratic equation , as shown by Sir Ronald Fisher in his establishment of quantitative genetics. This seldom occurs in nature: localization of gamete exchange – through dispersal limitations, preferential mating, cataclysm, or other cause – may lead to small actual gamodemes which exchange gametes reasonably uniformly within themselves but are virtually separated from their neighboring gamodemes. However, there may be low frequencies of exchange with these neighbors. This may be viewed as

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

In sociology and population geography , population refers to a group of human beings with some predefined feature in common, such as location, race , ethnicity , nationality , or religion . In ecology , a population is a group of organisms of the same species which inhabit

Researcher Carl Haub calculated that a total of over 100 billion people have probably been born in the last 2000 years. Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards. The last 50 years have seen a yet more rapid increase in the rate of population growth due to medical advances and substantial increases in agricultural productivity, particularly beginning in
689-611: Is often referred to as the demographic transition . Human population planning is the practice of altering the rate of growth of a human population. Historically, human population control has been implemented with the goal of limiting the rate of population growth. In the period from the 1950s to the 1980s, concerns about global population growth and its effects on poverty, environmental degradation , and political stability led to efforts to reduce population growth rates. While population control can involve measures that improve people's lives by giving them greater control of their reproduction,

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

Population has already declined in the last decade or two in Eastern Europe, the Baltics and in the former Commonwealth of Independent States. The population pattern of less-developed regions of the world in recent years has been marked by gradually declining birth rates. These followed an earlier sharp reduction in death rates. This transition from high birth and death rates to low birth and death rates

1113-720: The census of 2000, there were 131,676 people, 52,136 households, and 29,213 families residing within the MSA. The racial makeup of the MSA was 91.22% White , 2.49% African American , 0.27% Native American , 3.52% Asian , 0.04% Pacific Islander , 1.08% from other races , and 1.38% from two or more races. Hispanic or Latino of any race were 2.54% of the population. As of the 2013 US Census Bureau population estimate there were 161,170 people, an increase of 2800 people or 1.8% compared to 2012, due to 2,059 births, 651 international migrants and 889 from domestic migration.

Population Population is the term typically used to refer to the number of people in a single area.

This failure of panmixia leads to two important changes in overall population structure: (1) the component gamodemes vary (through gamete sampling) in their allele frequencies when compared with each other and with the theoretical panmictic original (this is known as dispersion, and its details can be estimated using expansion of an appropriate binomial equation ); and (2)
1961-515: 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

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,

All homozygotes are increased in frequency – both the deleterious and the desirable. The mean phenotype of the gamodemes collection is lower than that of the panmictic original – which is known as inbreeding depression. It is most important to note, however, that some dispersion lines will be superior to
2332-638: 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

In plant and animal breeding , procedures have been developed which deliberately utilize the effects of dispersion (such as line breeding, pure-line breeding, backcrossing). Dispersion-assisted selection leads to the greatest genetic advance (ΔG=change in

This is so for both allogamous (random fertilization) and autogamous (self-fertilization) gamodemes. According to the UN, the world's population surpassed 8 billion on 15 November 2022, an increase of 1 billion since 12 March 2012.

The area of a sexual population is the area where interbreeding is possible between any opposite-sex pair within the area and more probable than cross-breeding with individuals from other areas.

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.
