The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of decennial census data. Census Tract level data from the 2010 Census is mapped, analyzed, and compared to prior and subsequent Census years' Tract data in order to determine trends and patterns of change in the City of Richmond's population. This GIS layer is used to relate properties (hence addresses) to the correlating census tract for use in the City's data warehousing and address systems. |
