Census Bureau Announces Major Changes to 2020 American Community Survey (ACS) Data ReleaseJuly 30, 2021:
On July 29, the U.S. Census Bureau announced during a special webinar that due to impacts of the COVID-19 pandemic on the American Community Survey, the 2020 ACS 1-Year estimates will not be released as usual in September, nor will 2020 ACS data be included in related products (e.g., the CPS Health Insurance Report). This change comes as the pandemic resulted in substantially lower response rates and non-response bias that could affect the accuracy of estimates. Instead of the usual data products, the Census Bureau plans to release a set of 2020 ACS “Experimental” 1-year estimates for a more limited set of geographies, scheduled to be available in November 2021.
At this time, all 5-year ACS data products (e.g., estimates, PUMS files) for 2016-2020 are planned for release as normal in December 2021.
Resources available from the Census Bureau include:
- Slides from the webinar
- A press release detailing the impacts of COVID on the ACS data
- Revised release schedule and explanation of the experimental estimates
- A short informational guide to understanding how your work may be impacted by the change in the 2020 ACS data
SHADAC will continue to closely monitor future announcements and data releases related to the ACS, and we will assess whether and how any 2020 ACS data products can be used to produce state-level health insurance coverage and related estimates. We will also assess if and which other data sources may be useful for producing the coverage estimates we typically get from the ACS.
