Information about the U.S. Census


What is the Census

Please note: This guide covers only those statistical volumes released after census data has been compiled. This guide does not cover those older documents that list census participants by name, which are commonly used for tracking family histories. For that information, please use HeritageQuest Online (WTAMU only).

Article 1, Section 2, of the United States Constitution requires that a census be taken every 10 years for the purpose of apportioning the United States House of Representatives. The first census was taken in 1790, and since that time the census of population has been taken each year ending in zero. The United States was the first country to institute a periodic census. The decennial census results are used to determine the number of congressional seats apportioned to each state.

Texas currently has 36 members in the United States House of Representatives as a result of the apportionment based on the 2010 census figures. State and local governments also began to rely on the census to determine their own legislative representation and districting. Many questions on the decennial census are mandated by federal law.

As the needs of the nation changed, census questions were created to get statistics for different purposes. For example, the first inquiry on manufactures was made in 1810. Questions on agriculture, mining, and fisheries were added in 1840; and in 1850, the census included inquiries on social issues such as taxation, churches, pauperism, and crime. For more census background and history, please see History and Organization from the U.S. Census.

For Texas, Article III, Section 28, of the Texas Constitution requires the Texas Legislature to redistrict both houses (the Texas House of Representatives and Texas State Senate) at its first regular session after publication of the federal decennial census. The Legislature meets in odd-numbered years. If the Legislature fails to adopt a redistricting plan by the end of the legislative session, a Legislative Redistricting Board (the "LRB") consisting of the Lieutenant Governor, Comptroller of Public Accounts, Speaker of the House of Representatives, Attorney General, and Commissioner of the General Land Office shall convene within 90 days of adjournment and adopt a plan within 60 days of convening. For more information on this process, please visit Frequently Asked Questions Regarding The Census and Redistricting.
