The 2010 Census tract boundaries are used for Census Bureau statistical data tabulation purposes, including the 2010 Decennial Census and American Community Surveys.</p><p style='color: rgb(0, 0, 0); font-family: Arial; font-size: 13.3333px;'>Census tracts are part of the sub-county census geography hierarchy of tracts, block groups, and blocks. The three census geographies nest to each other, forming a hierarchy of census tract, followed by block groups, and then blocks, with blocks being the smallest. A census tract consists of one or more census block groups and is a cluster of census blocks within the same census tract. Tracts are uniquely identified within a County by a six digit number. The last two digits will be zeros unless earlier divisions of the census tract occurred as a result of population growth.</p><p style='color: rgb(0, 0, 0); font-family: Arial; font-size: 13.3333px;'>Loudoun County's tracts were delineated by Loudoun County Government during the Census Bureau's Participant Statistical Areas Program for the 2010 Census. The 2010 Census tract layer has been modified from the Census Bureau's Tiger line file. Users should be aware that the Census's Tiger line data is devised from a mix of national and local GIS data sets. When the Tiger line data is overlaid with Loudoun County Government's detailed GIS layers it can be determined that the Census Bureau's Tiger line boundaries in some cases are slightly off from the actual location of the physical features, natural features, and governmental units such as town boundaries that they are designated to follow. The 2010 Loudoun census tract layer was generated by Loudoun County so that the tract boundaries would overlay with the features in Loudoun County's GIS data sets that the boundary are designated to follow.</p>\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://geohub-loudoungis.opendata.arcgis.com/api/download/v1/items/ba33b5a637dc412ba6b15decd06e34f8/csv?layers=2\", \"format\": \"CSV\", \"mediaType\": \"text/csv\", \"title\": \"CSV\"}, {\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://geohub-loudoungis.opendata.arcgis.com/api/download/v1/items/ba33b5a637dc412ba6b15decd06e34f8/geojson?layers=2\", \"format\": \"GeoJSON\", \"mediaType\": \"application/vnd.geo+json\", \"title\": \"GeoJSON\"}, {\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://geohub-loudoungis.opendata.arcgis.com/api/download/v1/items/ba33b5a637dc412ba6b15decd06e34f8/kml?layers=2\", \"format\": \"KML\", \"mediaType\": \"application/vnd.google-earth.kml+xml\", \"title\": \"KML\"}, {\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://geohub-loudoungis.opendata.arcgis.com/api/download/v1/items/ba33b5a637dc412ba6b15decd06e34f8/shapefile?layers=2\", \"format\": \"ZIP\", \"mediaType\": \"application/zip\", \"title\": \"Shapefile\"}, {\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://geohub-loudoungis.opendata.arcgis.com/datasets/LoudounGIS::loudoun-2010-census-tracts\", \"format\": \"Web Page\", \"mediaType\": \"text/html\", \"title\": \"ArcGIS Hub Dataset\"}, {\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://logis.loudoun.gov/gis/rest/services/COL/Planning/MapServer/2\", \"format\": \"ArcGIS GeoServices REST API\", \"mediaType\": \"application/json\", \"title\": \"ArcGIS GeoService\"}], \"identifier\": \"https://www.arcgis.com/home/item.html?id=ba33b5a637dc412ba6b15decd06e34f8&sublayer=2\", \"issued\": \"2017-06-14T22:10:00.000Z\", \"keyword\": [\"Loudoun County\", \"Planning\", \"Planning and Zoning\", \"census\", \"census tracts\", \"clipandship\", \"open data\"], \"landingPage\": \"https://geohub-loudoungis.opendata.arcgis.com/datasets/LoudounGIS::loudoun-2010-census-tracts\", \"license\": \"<p><a href='https://logis.loudoun.gov/loudoun/disclaimer.html' rel='nofollow ugc' style='color: rgb(0, 121, 193); text-decoration-line: none; outline-color: rgb(0, 122, 194); font-family: &quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;' target='_blank'><font size='4'>Loudoun County GIS\\u00a0Disclaimer &amp; Contact Information</font></a><br /></p>\", \"modified\": \"2023-09-12T13:47:00.000Z\", \"publisher\": {\"name\": \"Loudoun County GIS\"}, \"spatial\": \"-77.9634,38.8488,-77.3240,39.3216\", \"theme\": [\"geospatial\"], \"title\": \"Loudoun 2010 Census Tracts\"}","source_transform":null,"status":"error"}
