Data Release Timeline of 2020 Census

August 12, 2021 

Redistricting demographic data released to the public.  The format of the data file requires special software to download and extract data.  Visualizations, data dashboards, and America Count stories explaining the finding will be available.

The final set of demonstration data for the redistricting data file released to the public.  Demonstration data allow data users to compare a differential privacy infused version of the 2010 Census results with the actual published 2010 Census results.  For more information on differential privacy see the "Privacy and Accuracy of 2020 Census Data" section below.

September 16, 2021 

A redistricting data toolkit released to the public.  This includes an online Data Explorer tool that will allow the redistricting 2020 Census demographic data to be easily viewed and extracted using the Census Bureau's data dissemination tool, data.census.gov.

May and August 2023

The Demographics and Housing Characteristics files for the 2020 Census will be released in phases in 2023.  The files will contain the 2020 Census data that was not released with the redistricting data file, including characteristics of the population  (i.e. age, sex), characteristics of households (i.e. household size, rent/own, families), and detailed race/ethnic breakdowns by place of origin, age, and other demographic characteristics.

On April 27, 2022, the U.S. Census Bureau announced a revised timeline for the final 2020 Census data products. 

  • The Demographic and Housing Characteristics File and Demographic Profile tables will be released by May 2023.

  • The Detailed Demographic and Housing Characteristics file will be released in three phases, with the first one scheduled for August 2023 and the final two had yet to have release dates determined.

Privacy and Accuracy of 2020 Census Data

For decades, the U.S. Census Bureau has used different techniques to protect individual privacy through their Disclosure Avoidance System (DAS).  Differential Privacy (DP) is the latest technique.  This technique was chosen because enhanced privacy protection is needed due to advances in technology that enable the ability to identify individuals when combined with other information.  DP will impact data accuracy more than any other technique previously applied to decennial census results.  DP will add random data (“noise”) to counts for geographic areas below the state level, to prevent identification of individuals.  The amount of noise added to the data will be greater than any prior decennial census technique.

Since 2019, Northern Virginia jurisdictions, through the Northern Virginia Regional Commission (NVRC), have been participating in the U.S. Census Bureau’s DP demonstration data review and provided feedback to the U.S. Census Bureau, with the latest provided for the April 2021 round, the U.S. Census Bureau's final round of feedback.  The following document is a brief overview of differential privacy and impacts it has on data quality.  Click on the image to download.
