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 March 27, 2023, the U.S. Census Bureau announced a revised product release timeline for the final 2020 Census data products. 

  • The Detailed Demographic and Housing Characteristics file will be released in three phases, with the first one being the Detailed DHC-A scheduled for September 2023.  The second one is the Detailed DHC-B and the third is the Supplemental DHC (S-DHC), both of which will have their scheduled release dates announced in May 2023.

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.
