Calculating Margins of Error the ACS Way Webinar

Learn how the American Community Survey (ACS) calculates margin of error (MOE) for estimates published on data.census.gov. See how to calculate MOEs when combining ACS estimates within a table or across geographies using the ACS Variance Replicate Estimates (VRE) tables. In addition, learn how to calculate your own estimates and MOEs using the Public Use Microdata Sample (PUMS) data.
