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.<\/SPAN><\/P>

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). <\/SPAN><\/P>

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. <\/SPAN><\/P>

All Census Bureau generated shapefiles are in Global Coordinate System North American Datum of 1983 (GCS NAD83). <\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "units": "esriFeet", "maxViewsCount": 20, "syncEnabled": false, "tables": [], "hasVersionedData": false, "hasViews": false, "layers": [ { "name": "QCT23_Tracts", "id": 4, "geometryType": "esriGeometryPolygon", "serviceItemId": "e0a2610f95a04f87aee4b921bd420d73" } ], "spatialReference": { "latestWkid": 2230, "wkid": 102646 }, "fullExtent": { "ymin": 1777091.8103025556, "xmin": 6213492.090608999, "ymax": 2101110.5749934018, "xmax": 6613421.826837167, "spatialReference": { "latestWkid": 2230, "wkid": 102646 } }, "enableZDefaults": true, "allowUpdateWithoutMValues": true, "isLocationTrackingService": false, "supportedExportFormats": "sqlite,filegdb", "capabilities": "Query", "supportsAppend": true, "supportsDisconnectedEditing": false, "supportedAppendFormats": "shapefile,featureCollection", "supportsReturnDeleteResults": true, "currentVersion": 10.91, "advancedEditingCapabilities": {"supportsAsyncApplyEdits": false}, "supportedQueryFormats": "JSON", "initialExtent": { "ymin": 1761272.1383279865, "xmin": 6153117.916952226, "ymax": 2143791.9560395475, "xmax": 6611082.819817971, "spatialReference": { "latestWkid": 2230, "wkid": 102646 } }, "serviceDescription": "", "editorTrackingInfo": { "allowOthersToUpdate": true, "enableEditorTracking": false, "allowOthersToDelete": false, "allowOthersToQuery": true, "enableOwnershipAccessControl": false }, "hasSyncEnabledViews": false, "copyrightText": "SANGIS using data provided by the United States Census Bureau (TIGER).", "zDefault": 0, "serviceItemId": "e0a2610f95a04f87aee4b921bd420d73" }
