This dataset comprises polygons of census tracts for San Diego County. A census tract is a geographic region defined for the purpose of taking a census. Usually these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county. In unincorporated areas, these are often arbitrary, except for coinciding with political lines. Census tracts are subdivided into block groups and census blocks.The TIGER/Line Files are to tl_2020_06_tract.shp was downloaded from https://www.census.gov/cgi-bin/geo/shapefiles/index.php. Features intersecting San Diego County boundary were extracted and projected to NAD 83 State Plane. The TIGER/Line Shapefiles are extracts of selected geographic and cartographic information from the Census Bureau's Master Address File (MAF)/topologically Integrated Geographic Encoding and Referencing (TIGER) Database (MTDB). The TIGER/Line Shapefiles contain a standard geographic identifier (GEOID) for each entity that links to the GEOID in the data from censuses and surveys. All Census Bureau generated shapefiles are in Global Coordinate System North American Datum of 1983 (GCS NAD83).<\/SPAN><\/P><\/DIV><\/DIV>", "copyrightText": "SANGIS using data provided by the United
