The American Community Survey (ACS) is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. The ACS covers a broad range of topics about social, economic, demographic, and housing characteristics of the U.S. population. Much of the ACS data provided on the Census Bureau's Web site are available separately by age group, race, Hispanic origin, and sex.
Detailed Tables, Subject Tables, Data Profiles, Comparison Profiles and Selected Population Profiles are available for the nation, all 50 states, the District of Columbia, Puerto Rico, every congressional district, every metropolitan area, and all counties and places with populations of 65,000 or more.
For more information about the data available in the ACS, please visit its data users page.
Variables, and the values they represent, may change over time. If you have used variables in prior year releases, check the ACS product changes webpage for source table changes. If the variable you have been using comes from a table that has changed from the prior year, check the variables list (variables.html) and compare the variable concept and label to be sure you are requesting the correct estimate.

In September 2016, ACS released annotation variables that return character representations of each estimate. Many annotations return as null. However, if an annotation variable returns a value, it provides important information about the estimate or margin of error. For example, if an estimate variable (variable ending in “E”) returns “-888888888”, the annotation variable will return “(X)”. Looking at the Notes on ACS Estimate and Annotation Values, this means the estimate is not applicable or not available. For a complete list of return values and their annotations, see:
