United States Census Bureau发表评论(0)编辑词条

The United States Census Bureau (USCB; officially the Bureau of the Census, as defined in Title 13 U.S.C. § 11) is a principal agency of the U.S. Federal Statistical System responsible for producing data about the American people and economy.

The primary mission of the Census Bureau 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. In addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U.S. Economic Census, and the Current Population Survey.[1] Furthermore, economic and foreign trade indicators released by the federal government typically contain data produced by the Census Bureau. The various censuses and surveys conducted by the Census Bureau help allocate over $400 billion in federal funds every year and help states, local communities, and businesses make informed decisions.

The Census Bureau is situated within the U.S. Department of Commerce and its director is appointed by the President of the United States.

The Constitution of the United States (Article I, section II) directs that 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 10 years in years ending with a 0 (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 much more. The Census Bureau is mandated with fulfilling these obligations: the collecting of statistics about the nation, its people, and economy. The Census Bureau's legal authority is codified in Title 13 of the United States Code.

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, 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 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 2 years and agriculture censuses every 10 years. In 1929, a bill was passed mandating that the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code.

By law the Census Bureau must count everyone and submit state population totals to the U.S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year.

Census regions and divisions

The United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are "widely used...for data collection and analysis." The Census Bureau definition is pervasive.

Regional divisions used by the United States Census Bureau:

Region 1: Northeast
Division 1: New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont)
Division 2: Mid-Atlantic (New Jersey, New York, and Pennsylvania)
Region 2: Midwest (Prior to June 1984, the Midwest Region was designated as the North Central Region.)
Division 3: East North Central (Illinois, Indiana, Michigan, Ohio, and Wisconsin)
Division 4: West North Central (Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota)
Region 3: South
Division 5: South Atlantic (Delaware, Florida, Georgia, Maryland, North Carolina, South Carolina, Virginia, Washington D.C., and West Virginia)
Division 6: East South Central (Alabama, Kentucky, Mississippi, and Tennessee)
Division 7: West South Central (Arkansas, Louisiana, Oklahoma, and Texas)
Region 4: West
Division 8: Mountain (Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming)
Division 9: Pacific (Alaska, California, Hawaii, Oregon, and Washington)

Many federal, state, local and tribal governments use census data to:

Decide the location of new housing and public facilities,
Examine the demographic characteristics of communities, states, and the USA,
Plan transportation systems and roadways,
Determine quotas and creation of police and fire precincts, and
Create localized areas for elections, schools, utilities, etc.

Since 1903, the official census-taking agency of the United States government has been the Bureau of the Census. The Census Bureau is headed by a Director, assisted by a Deputy Director and an Executive Staff composed of the associate directors.

The Census Bureau has had headquarters in Suitland, Maryland, since 1942. A new headquarters complex was completed in 2007 and supports over 4,000 employees. The Bureau operates regional offices in 12 cities: Boston, New York City, Philadelphia, Detroit, Chicago, Kansas City, Seattle, Charlotte, Atlanta, Dallas, Denver, and Los Angeles. The National Processing Center is located in Jeffersonville, Indiana. Additional temporary processing facilities are used to facilitate 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 "Local Census Offices" within their collection jurisdictions. The estimated cost of the 2010 Census is $14.7 billion.

On January 1, 2013, the Census Bureau was to consolidate its 12 regional offices into 6. 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) has led the Census Bureau to consolidate. The remaining regional offices are to be located in: New York City, Philadelphia, Chicago, Atlanta, Denver, and Los Angeles.

The Census Bureau also runs the Census Information Center cooperative program that involves 58 "national, regional, and local non-profit organizations." The CIC program aims to represent the interests of underserved communities.

The 1890 census was the first to use the electric tabulating machines invented by Herman Hollerith.[25][26] For 1890–1940 details, see Truesdell, Leon E. (1965). The Development of Punch Card Tabulation in the Bureau of the Census, 1890-1940: With outlines of actual tabulation programs. US GPO. In 1946, knowing of the Bureau's funding of Hollerith and, later, Powers, John Mauchly approached the Bureau about early funding for UNIVAC development. A UNIVAC I computer was accepted by the Bureau in 1951.

In order to reduce paper usage and reduce payroll expenses, 500,000 handheld computers (HHCs) 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.
