#### Description

The United States Census Bureau regularly releases
a geodatabase named TIGER. This dataset contains the 2020 census
[block groups](https://www.census.gov/programs-surveys/geography/about/glossary.html#par_textimage_4),
which is a cluster of blocks within the same census tract that have the same
first digit of their four-digit census block number. There are just over
240,000 polygon features covering the United States, the District
of Columbia, Puerto Rico, and the
Island areas.

For full technical details on all TIGER 2020 products, see the
[TIGER technical documentation](https://www2.census.gov/geo/pdfs/maps-data/data/tiger/tgrshp2020/TGRSHP2020_TechDoc.pdf).
