Loudoun 2020 Census Tracts

Metadata Updated: February 9, 2024

This GIS layer contains the geographical boundaries of the 2020 census tracts for Loudoun County, Virginia. The 2020 Census tract boundaries are used for Census Bureau statistical data tabulation purposes, including the 2020 Decennial Census and American Community Surveys. 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. Tracts are designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions. They generally have at least 1,200 people or 480 housing units, and no more than 8,000 people or 3,200 housing units, with an optimal size of 4,000 people or 1,600 housing units. This 2020 Census tract GIS layer's boundaries are based on the U.S. Census Bureau Census 2020 TIGER/Line files. The boundaries are an extract of aerial photography and cartographic information, such as roads and streams, from the Loudoun County GIS system. Census tracts are bounded on all sides by visible features, such as roads, streams, lakes, power lines, and railroad tracks, and/or by non-visible boundaries such as town and county boundaries, and short line-of-sight extensions of streets and roads.
