The Census Bureau's Planning Database (PDB) contains select select operational, demographic and socio-economic statistics from the 2010 Census and the American Community Survey 5-year files and the Census Bureau's low response score (LRS), where the LRS is a predicted value of mail self-response. Except for ACS response rates and the LRS, statistics are provided at the block group and tract levels of geography. The PDB was designed as an aid for survey and census planning, but has many potential uses. For example, given its ease of use, one may consider using the PDB for instructional purposes.
For more information on the LRS, see Erdman and Bates 2017 [PDF <1.0 MB ].
For visual displays of key PDB statistics, see Response Outreach Area Mapper (ROAM).
The 2020 PDB contains select operational, demographic, and socio-economic statistics from the 2010 Census and the 2014-2018 5-year ACS, including the segmentation profile statistic carried forward from the 2019 PDB and current ACS response rates. Data are available at both the tract and block group levels. For 2020, non-operational statistics are also available at the state and county levels.

When presenting packages to the DRB that include such data, their provenance must be documented to the satisfaction of the DRB.
