Relationship Files

Within Census Geographies

Relationship Files

These text files describe geographic relationships. There are two types of relationship files; those that show the relationship between the same type of geography over time (comparability) and those that show the relationship between two types of geography for the same time period.

2023
  • 2023
  • 2022
  • 2020
  • 2010
  • 2000
2023

These relationship files provide simple relationships between 2020 tabulation entities and the newly defined Core Based Statistical Areas (CBSAs). The newly defined CBSAs first appeared in products for the 2023 American Community Survey (ACS).

Geographic Relationships Between Entity Types

These files show the relationship between different types of geography for the same time period (e.g., the relationships between urban areas and core based statistical areas).
