2019 ACS 1-year Supplemental Estimates

New and Deleted Tables

Quality Measures

The Census Bureau is replacing the unweighted interview count tables K200001 and K200002 with K209801 and K209803, which consolidates all unweighted interview counts into the quality measures series. The quality measures tables containing sample sizes and unweighted interview counts will continue to be published for nation, state, county and place in the 1-year and 5-year products and will be added to the 1-year Supplemental Estimates for the first time.

Modified Tables

Journey to Work and Migration

Beginning in 2019, the Census Bureau implemented changes to selected means of transportation categories based on the results of the 2016 American Community Survey (ACS) Content Test. A category label for Table K200801 changed to implement these changes.
