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 a zero and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population estimates and projections.{{cite web |url=https://www.census.gov/popest/estimates.php |title=Population Estimates |date=May 31, 2006 |publisher=U.S. Bureau of the Census |url-status=dead |archive-url=http://webarchive.loc.gov/all/20061206215954/http://www.census.gov/popest/estimates.php |archive-date=December 6, 2006 }}

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.{{Cite web|url=https://www.census.gov/2010census/partners/pdf/2010_TQA_Agent_FAQs_english.pdf|date=May 10, 2010 |website= U.S. Census |title=2010 Census Frequently Asked Questions |access-date=October 4, 2017|archive-url=https://web.archive.org/web/20170723102105/https://www.census.gov/2010census/partners/pdf/2010_TQA_Agent_FAQs_english.pdf|archive-date=July 23, 2017|url-status=dead}} 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.{{Cite journal |last=Lunt |first=Edward C. |date=1888 |title=History of the United States Census |url=https://www.jstor.org/stable/2276342 |journal=Publications of the American Statistical Association |volume=1 |issue=2/3 |pages=63–93 |doi=10.2307/2276342 |jstor=2276342 |issn=1522-5437|url-access=subscription }}{{Cite web |date=November 14, 2008 |title=History: 1790 |url=https://www.census.gov/history/www/overview/012270.html |url-status=dead |archive-url=https://web.archive.org/web/20090303145157/https://www.census.gov/history/www/overview/012270.html |archive-date=March 3, 2009 |website=U.S. Census Bureau}} The Census Act of 1840 established a central office{{cite web |url-status=dead |url=https://www.census.gov/history/www/overview/012275.html |title=History: 1840 |archive-url=https://web.archive.org/web/20090303143456/http://www.census.gov/history/www/overview/012275.html |archive-date=March 3, 2009 |website=US Census Bureau |date=November 14, 2008 }} 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."[https://www.census.gov/history/www/through_the_decades/overview/1900.html History: 1900 Overview]".

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.[https://www.census.gov/history/www/overview/012283.html History 1920]. {{webarchive|url=https://web.archive.org/web/20090303145212/http://www.census.gov/history/www/overview/012283.html |date=March 3, 2009 }}.

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.

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 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 divisions", 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 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 the Pacific division upon statehood in 1959, and the North Central region was renamed the Midwest in 1984.[https://www2.census.gov/geo/pdfs/reference/GARM/Ch6GARM.pdf Statistical Groupings of States and Counties] {{Webarchive|url=https://web.archive.org/web/20220129035331/https://www2.census.gov/geo/pdfs/reference/GARM/Ch6GARM.pdf |date=January 29, 2022 }} (PDF)

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 the disclosure of this information. All census employees must sign an affidavit of non-disclosure prior to employment. This non-disclosure states {{qi|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.}}{{Cite web |publisher=United States Census Bureau |title=Oath of Non-Disclosure |url=https://www.census.gov/about/policies/privacy/data_stewardship/oath_of_non-disclosure.html |access-date=May 5, 2024 |website=Census.gov}} The punishment for breaking the non-disclosure is a fine up to $250,000 or five years in prison.

The bureau cannot share responses, addresses or personal information with anyone, including the United States or foreign governments, or law enforcement agencies such as the IRS or the FBI or Interpol. {{qi|Providing quality data, for public good—while respecting individual privacy and, at the same time, protecting confidentiality—is the Census Bureau's core responsibility}}; {{qi|Keeping the public's trust is critical to the Census's ability to carry out the mission as the leading source of quality data about the Nation's people and economy.}}{{citation|url=https://www.census.gov/po/www/foia/D590.pdf|date=April 2009|title=Census Employee Handbook|url-status=dead|archive-url=https://web.archive.org/web/20120117214039/http://www.census.gov/po/www/foia/D590.pdf|archive-date=January 17, 2012}} Only after 72 years does the information collected become available to other agencies or the general public.{{cite web|title=72-Year Rule|url=https://www.census.gov/history/www/genealogy/decennial_census_records/the_72_year_rule_1.html|website=U.S. Census Bureau|access-date=November 20, 2015|archive-date=April 16, 2019|archive-url=https://web.archive.org/web/20190416202132/https://www.census.gov/history/www/genealogy/decennial_census_records/the_72_year_rule_1.html|url-status=live}} 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.

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.{{cite book|last=Nobles|first=Melissa|date=2000|title=Shades of Citizenship: Race and the Census in Modern Politics|location=Stanford, CA|publisher=Stanford University Press|page=ix|isbn=9780804740135}} These insights are often linked to financial and economic strategies that are central to federal, state and city investments for locations of particular populations.{{cite journal|last1=Breiman|first1=Leo|date=1994|title=The 1991 Census Adjustment: Undercount or Bad Data?|journal=Statist.

The United States Census Bureau began pursuing technological innovations to improve the precision of its census data collection in the 1980s. Robert W. Marx, the Chief of the Geography Division of the USCB, teamed up with the U.S. Geological Survey and oversaw the creation of the Topologically Integrated Geographic Encoding and Referencing (TIGER) database system.{{cite magazine |author= |url=http://www.aag.org/cs/membership/tributes_memorials/mr/marx_robert_w |title=Memorials and Tributes: Robert W.

And while the TIGER system does not directly amass demographic data, as a geographic information system (GIS), it can be used to merge demographics to conduct more accurate geospatial and mapping analysis.{{cite journal |last1=Ostenso|first1=John|date=1991|title=The Statistics Corner: More New Products from the Census Bureau |jstor=23485837 |journal=Business Economics|volume=26|issue=4|pages=62–64}}

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 headquarters has been in Suitland, Maryland, since 1942. A new headquarters complex completed there in 2007 supports over 4,000 employees.{{Cite web

New York City, Philadelphia, Chicago, Atlanta, Denver, and Los Angeles. The National Processing Center is in Jeffersonville, Indiana. Additional temporary processing facilities 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 "Area Census Offices" within their collection jurisdictions. In 2020, Regional Census Centers oversaw the operation of 248 Area Census Offices,{{cite web|last=United States Census Bureau|date=December 31, 2018|title=2020 Census Operational Plan v4.0|url=https://www2.census.gov/programs-surveys/decennial/2020/program-management/planning-docs/2020-oper-plan4.pdf|access-date=January 20, 2021|website=Census.gov|archive-date=August 2, 2019|archive-url=https://web.archive.org/web/20190802113646/https://www2.census.gov/programs-surveys/decennial/2020/program-management/planning-docs/2020-oper-plan4.pdf|url-status=live}} 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.{{cite web | title=A Restructuring of Census Bureau Regional Offices | publisher=U.S. Bureau of the Census | url=http://directorsblog.blogs.census.gov/2011/06/29/a-restructuring-of-census-bureau-regional-offices/ | access-date=June 21, 2012 | url-status=dead | archive-url=https://web.archive.org/web/20120611033428/http://directorsblog.blogs.census.gov/2011/06/29/a-restructuring-of-census-bureau-regional-offices/ | archive-date=June 11, 2012 | df=mdy-all }} The six regional offices that closed were Boston, Charlotte, Dallas, Detroit, Kansas City and Seattle.

Historically, the census information was gathered by census takers going door-to-door collecting information in 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.{{cite web |url-status=dead |url=http://www.govcomm.harris.com/solutions/products/000138.asp |website=Harris |title=U.S. Census Bureau Field Data Collection Automation (FDCA) Program |archive-url=https://web.archive.org/web/20090429014955/http://www.govcomm.harris.com/solutions/products/000138.asp |archive-date=April 29, 2009 }}{{cite web|last1=Weinberg|first1=Daniel|title=Management challenges of the 2010 U.S. Census|url=https://www.census.gov/history/pdf/weinberg-managing2010.pdf |date=July 28, 2011 |publisher=U.S. Census Bureau|access-date=December 29, 2015|archive-date=January 27, 2016|archive-url=https://web.archive.org/web/20160127153113/https://www.census.gov/history/pdf/weinberg-managing2010.pdf|url-status=live}}House Committee on Oversight and Reform, Subcommittee on Information Policy, Census and National Archives, [https://web.archive.org/web/20090625005513/http://informationpolicy.oversight.house.gov/story.asp?ID=2467 "Chairman Clay Pleased With Census Address Canvassing Progress"].

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 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 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,{{Cite web |last=O'Hare |first=William |title=Investigating the 2010 Undercount of Young Children – Summary of Recent Research |url=https://www.census.gov/programs-surveys/decennial-census/decade/2020/planning-management/plan/final-analysis/2020-report-2010-undercount-children-summary-recent-research.html |access-date=September 28, 2023 |website=2020 Census Final Analysis Reports}} overcount,{{Cite web |last=Sha |first=Mandy |title=Success of Applying Census Residence Rule to Resolve Duplication |url=https://www.census.gov/library/working-papers/2014/adrm/ssm2014-04.html |access-date=September 28, 2023 |website=Census Working Papers}} the use of technologies,{{Cite web |last=Nichols |first=Elizabeth |title=Use of Mobile Phone Location Data in Official Statistics |url=https://www.census.gov/library/working-papers/2023/adrm/rsm2023-03.html |access-date=September 28, 2023 |website=Census Working Papers}} multilingual research,{{Cite web |last=Sha |first=Mandy |title=Multilingual Research for Interviewer Doorstep Messages Final Report |url=https://www.census.gov/library/working-papers/2018/adrm/rsm2018-08.html |access-date=February 29, 2024 |website=Census Working Papers}} and ways to reduce costs.
