TIGER/Line Geodatabases are spatial extracts from the Census Bureau’s Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) System for use with geographic information systems (GIS) software. The geodatabases contain national coverage (for geographic boundaries or features) or state coverage (boundaries within state).
These files do not include demographic data, but they contain geographic entity codes that can be linked to the Census Bureau’s demographic data, available on data.census.gov.
See the documentation for the description of geographic boundaries and features contained in each geodatabase. Further details of the geographic boundaries and features can be found in the TIGER/Line Shapefiles technical documentation. These files will be released up to two times a year.
For the 118th Congressional District Geodatabase, all legal boundaries and names are as of January 1, 2023. Only the 118th Congressional Districts and the legislative year 2022 State Legislative Districts are included with this release.
