TIGER: US Census Tracts

  • The TIGER/2020/TRACT dataset provides 2020 US Census tract boundaries, covering the United States, District of Columbia, Puerto Rico, and Island areas.

  • Census tracts are roughly equivalent to neighborhoods in urban areas and are represented as polygons, totaling over 85,000 features.

  • This dataset includes attributes like land and water area, geographic identifiers, and census tract names.

  • Users can access and analyze the dataset through Google Earth Engine using provided code snippets and FeatureView for visualization.

  • The data is subject to US Census Bureau terms of use and requires proper citation when used in publications or derived products.

Description

The United States Census Bureau regularly releases a geodatabase named TIGER. This dataset contains the 2020 census tracts. Tract areas vary tremendously, but in urban areas are roughly equivalent to a neighborhood. There are just over 85000 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.
