Press Release Number CB24-CN.15
The U.S. Census Bureau today provided an update on the final three data products from the 2020 Census.
Detailed Demographic and Housing Characteristics File B (Detailed DHC-B) — Aug. 1.
The Detailed DHC-B provides household type and tenure information, including total household counts, for approximately 1,500 detailed race and ethnicity groups and detailed American Indian and Alaska Native (AIAN) tribes and villages. The final table shells are included on the “Detailed DHC A & B Tables” tab of the 2020 Census Data Product Crosswalk. Embargo subscribers can access these statistics beginning 10 a.m. EDT, Tuesday, July 30, for release at 12:01 a.m. EDT, Thursday, August 1. A webinar on the upcoming release is scheduled for July 23. More details are forthcoming.
Privacy-Protected Microdata Files (PPMF) — Aug. 5. (tentative)
The PPMF provides the complete set of privacy-protected records used to create the Redistricting Data Summary File (P.L. 94-171), Demographic Profile, and the Demographic and Housing Characteristic File (DHC). The PPMF consists of separate files for people and housing units. The files include geocode identifiers down to the census block level, enabling data users to generate custom tabulations for numerous geographic levels.
Supplemental Demographic and Housing Characteristics File (S-DHC) — Sept. 19.
The S-DHC tables combine the characteristics of households and the people living in them at the state and national level. These tables supplement the data about households and people available in the DHC, providing average household size and counts of people living in certain types of households. The final table shells are included on the “SDHC Tables” tab of the 2020 Census Data Product Crosswalk. Embargo subscribers can access these statistics beginning 10 a.m. EDT, Tuesday, Sept. 17, for release at 12:01 a.m. EDT, Thursday, Sept. 19.
The Detailed DHC-B, PPMF and S-DHC may also be accompanied by reports and results in other forms. The Census Bureau has moved deliberately to ensure that it produces the high-quality statistics that the public expects. The pandemic delayed 2020 Census operations, and the Census Bureau worked diligently to implement new confidentiality protections.
