This map shows areas that aren't represented in the Census Bureau's standard geographies. Data is computed for these areas by assigning Census blocks to the areas where the center point (“internal point”) of the blocks fall, and then totalling the block-level data as reported by Census.
While this is a standard method which generally works well, this process can be imprecise, missing blocks that a local person would recognize as part of a neighborhood, or including blocks which are outside of the mapped area, such as in a neighboring city.
Without local knowledge, we can't make accurate adjustments to this automated process. You should treat this data as approximate—suitable for making general observations but not for precise comparisons.

Each link will download a ZIP file containing the data for the given table in both CSV and GeoJSON format. Except where noted, data includes counts for 2020 and 2010, as well as precomputed percent-change.
Consult the metadata.json file in the ZIP file for a mapping from column codenames to their meanings.
Each link will download a ZIP file containing the Census blocks for the given year in both CSV and GeoJSON format, as they are associated with the various geographies in this map. The Block Assignment Files also include the total population and housing unit count for each block, as well as the Census state/place FIPS codes, which can be useful for auditing the automated block assignment process.
