This dataset contains the 2020 census blocks, roughly equivalent to a city block. There are just over eight million polygon features covering the United States, the District of Columbia, Puerto Rico, and the [Island areas](https://www.census.gov/programs-surveys/decennial-census/decade/2020/planning-management/release/2020-island-areas-data-products.html). 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). ### Table Schema **Table Schema** | Name | Type | Description | |---|---|---| | ALAND20 | DOUBLE | 2020 Census land area | | AWATER20 | DOUBLE | 2020 Census water area | | BLOCKCE20 | STRING | 2020 Census tabulation block number | | COUNTYFP20 | STRING | 2020 Census county FIPS code | | FUNCSTAT20 | STRING | 2020 Census functional status | | GEOID20 | STRING | Census block identifier: a concatenation of 2020 Census state FIPS code, 2020 Census county FIPS code, 2020 Census tract code, and 2020 Census block number | | INTPTLAT20 | STRING | 2020 Census latitude of the internal point | | INTPTLON20 | STRING | 2020 Census longitude of the internal point | | MTFCC20 | STRING | MAF/TIGER feature class code | | NAME20 | STRING | 2020 Census tabulation block name: a concatenation of Block and the tabulation block number | | STATEFP20 | STRING | 2020 Census state FIPS code | | TRACTCE20 | STRING | 2020 Census tract code | | UACE20 | STRING | 2020 Census urban area code | | UATYPE20 | STRING | 2020 Census urban area type | | UR20 | STRING | 2020 Census urban/rural indicator | ### Terms of Use **Terms of Use** The U.S. Census Bureau offers some of its public data in machine-readable format via an Application Programming Interface (API).
