The U.S. Census Bureau held a prerelease webinar Sept. 16 to discuss the 2020 Census Supplemental Demographic and Housing Characteristics File (S-DHC) scheduled for public release Sept. 19. This is the final 2020 Census data product to be released.

The S-DHC provides average household size and counts of people living in certain types of households, and most of the tables are also available by race and Hispanic origin. The product supplements data about households and people published in the DHC in May 2023.

The S-DHC data are available for the nation, the 50 states, the District of Columbia and Puerto Rico. The final table shells are on the “SDHC Tables” tab of the 2020 Census Data Product Crosswalk.

The webinar also provided guidance for data users and included information on how to access the data. A live Q&A session with Census Bureau subject-matter experts followed the briefing.
