Resources for 2020 ACS Data Release

The Census Bureau has released the standard, full suite of 2016–2020 ACS 5-year data products—down to the block group level. The 2016-2020 ACS 5-year Public Use Microdata Sample (PUMS) files and Variance Replicate Estimates are also available. The Census Bureau revised its methodology to reduce nonresponse bias in data collected in 2020, and after evaluating the effectiveness of this methodology, has determined the resulting data are fit for public release. The Census Bureau provides additional information and guidance on their ACS New and Notable webpage and in their press kit

Due to the impact of the COVID-19 pandemic on ACS data collection in 2020, the Census Bureau released a series of experimental estimates from the 1-year ACS data. This release included a limited number of data tables for the nation, states, and District of Columbia. Census Bureau staff created an Experimental Data web page with links to the data tables, technical documentation, and other resources for data users.
