Planning Database

The Census Bureau's Planning Database (PDB) contains select operational, housing, demographic, and socio-economic statistics from the 2010 Census and the American Community Survey (ACS) 5-year files. It also contains the Low Response Score (LRS), where the LRS is a predicted value of mail self-response. With few exceptions, notably ACS response rates, statistics are provided at both the block group and tract levels. 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).

For visual displays of key PDB statistics, see Response Outreach Area Mapper (ROAM).

Data and Documentation

We recommend managing the files in a statistical software application such as R or SAS, as Excel may truncate columns or rows. We also urge users to verify that the downloaded file contains the indicated number of columns and rows: Block Group - [pdb2012bgv9_us.csv - 158531 KB, 220354 rows x 179 columns]. If the number of rows and columns do not align with these counts, verify that the download has not been interrupted or corrupted. If so, we recommend you try to re-download the file from a different web browser.

Statistics downloaded from American FactFinder or data.census.gov received clearances from the Disclosure Review Board before being posted. No clearance number is required at this time for such information products. When presenting packages to the DRB that include such data, their provenance must be documented to the satisfaction of the DRB.

2010 Census operational statistics were cleared by the DRB on 5/21/2012.
