Reminder: Please Submit 2020 Census Data Product Planning Crosswalk Comments by 10/22/21

Gray Divider

Oct. 14, 2021 — Reminder: Please submit all comments about the proposed 2020 Census data tables for both the Demographic and Housing Characteristics File (DHC) and Detailed DHC by Friday, October 22. Send comments to with “2020 Census Data Products” in the subject line. Staff and decisionmakers are reviewing all submissions.

Using the 2020 Census Data Product Planning Crosswalk, please share detailed descriptions of your use cases for specific tables: how you rely on the table content as well as the geographic specificity. The most useful feedback would include detailed descriptions of your use cases from the crosswalk. This would include how the needs of your work, your community, or your organization would be affected if that content or specificity were no longer available.

The Census Bureau is working to produce as many data tables with as much specificity as possible. We want to ensure that we are expending privacy-loss budget on those data details that potentially have the greatest impact while still preserving respondent confidentiality.
