2014 ACS 1-Year Supplemental Estimates

We are pleased to announce the release of the 2014 American Community Survey (ACS) 1-year supplemental estimates,

The ACS is the most relied-on source for up-to-date social, economic, demographic, and housing information every year. Supplemental estimates provide this data for geographies with populations of 20,000 or more, compared to the 65,000 population minimum for the standard ACS 1-year estimates. They 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 20,000 or more.

Visit the Census Bureau's American FactFinder or use Census API to start exploring these estimates.

Statistical Testing Tool

The statistical testing tool is a new spreadsheet that tests whether American Community Survey (ACS) estimates are statistically different from one another. It can perform statistical testing on individual pairs of ACS data or multiple ACS estimates simultaneously. Simply copy or download ACS estimates and their margins of error (MOE) into the tool to get instant results of statistical tests

To access the tool and learn about its full features, please visit the statistical testing tool page.

2010-2014 ACS Variance Replicate Estimate Tables

We are pleased to announce the release of the 2010-2014 ACS variance replicate estimate tables. These tables include estimates, margins of error (MOEs), and 80 variance replicate estimates for selected ACS 5-year detailed tables. With the replicate estimates, advanced users can calculate MOEs when collapsing data within a table or across geographies. This method provides a more accurate MOE than available approximation formulas.

Visit the Census Bureau's File Transfer Protocol (FTP) site and the new variance replicate estimate tables webpage to access these estimates.
