The Census Bureau is set to release ACS 5-year Public Use Microdata Sample (PUMS) files on March 5, 2026. To view the complete release schedule, visit the 2024 ACS data release schedule.

For more information on ACS topics, visit Subjects Included in the Survey. To access the full set of statistics released today, visit data.census.gov. ACS estimates from 2005 to 2009 are available via the Application Programming Interface (API) and Summary File - they are not available on data.census.gov. The ACS provides both handbooks and webinars on the API and the Summary File for those looking to access data through these tools. The ACS estimates from 2010 to present are available on data.census.gov, as well as the API and Summary File.

The United States Office of Management and Budget (OMB) delineates metro and micro areas according to published standards that are applied to Census Bureau data. Metro areas consist of the county or counties (or equivalent entities) associated with at least one urban area of at least 50,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties. Micro areas consist of the county or counties (or equivalent entities) associated with at least one urban area of at least 10,000 but less than 50,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties. More information about metro and micro areas can be found on our website.

Statistics from sample surveys are subject to sampling and nonsampling errors. All comparisons in the highlights have been tested and found to be statistically significant at the 90% confidence level, unless otherwise noted. Consult the tables on data.census.gov for specific margins of error. For more information on using margins of error, visit the Code Lists, Definitions, and Accuracy page.

There are several points to consider when comparing ACS estimates over time. For more information on comparing the 2024 statistics, refer to our comparison guidance page.

These statistics would not be possible without the participation of the survey respondents throughout the United States.
