Improvements to the 2020 Census Race and Hispanic Origin Question Designs, Data Processing, and Coding Procedures
The U.S. Census Bureau has collected data on race since the first census in 1790 and on Hispanic or Latino origin (referred to as Hispanic origin in this blog) since the 1970 Census. How these topics are measured, and statistics on them are collected and coded, has changed nearly every decade throughout the history of the census, reflecting social, political and economic factors.
