January 23, 2024: On January 29, the Census Bureau will release a Proof of Concept for the 2020 Census Detailed Demographic and Housing Characteristics File B (Detailed DHC-B) for public review and feedback. The Detailed DHC-B includes household type and tenure data for approximately 1,500 detailed racial and ethnic groups and American Indian and Alaska Native tribes and villages. This Proof of Concept illustrates the proposed 2020 Census Detailed DHC-B data product design and disclosure avoidance settings using 2010 Census data. 

As with the Detailed DHC-A Proof of Concept, the Detailed DHC-B Proof of Concept describes the amount of data planned for detailed groups, data processing, data accuracy, and data inconsistencies. It includes the Detailed Summary Metrics and Tenure Examples by applying a new disclosure avoidance methodology to 2010 Census data along with other resources. 

A 30-day public feedback period on the Proof of Concept concludes on February 28.

The final Detailed DHC-B based on 2020 Census data will be released in September 2024.

Join us Monday, January 29 at 3 p.m. ET for a webinar to learn more about the Detailed DHC-B Proof of Concept and the next steps in finalizing the data product design and disclosure avoidance settings.
