- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using tools in ArcGIS. The SDC data set is then imported into a file geodatabase to verify, validate, and if needed repair the geometry.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- Horizontal positional accuracy is dependent on geographic area. In most areas, accuracy is between 5 and 25 meters (16 and 82 feet). In some areas, accuracy is off by up to several tens of meters (100 feet or more). In the poorest areas, accuracy is off by up to 100 meters (328 feet).

- Entity Type Definition
- The polygons represent the U.S. Census tracts within the United States. Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity that are updated by local participants prior to each decennial census as part of the Census Bureau's Participant Statistical Areas Program. The Census Bureau delineates census tracts in situations where no local participant existed or where other government entities declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of statistical data. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. Census tract boundaries are delineated with the intention of being maintained over a long time so that statistical comparisons can be made from census to census. Census tracts occasionally are split due to population growth or merged as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow nonvisible legal boundaries, such as minor civil division (MCD) or incorporated place boundaries in some states and situations, to allow for census-tract-to-governmental-unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. The Census Bureau uses suffixes to help identify census tract changes for comparison purposes. When a census tract is split, the split parts usually retain the basic number but receive different suffixes. Changes to individual census tract boundaries usually do not result in census tract numbering changes. The code range in the 9800s is new for 2010 and is used to specifically identify special land-use census tracts, such as large parks or employment areas. The range of census tracts in the 9900s represents census tracts delineated specifically to cover large bodies of water. This is different from Census 2000 when water-only census tracts were assigned codes of all zeroes (000000); 000000 is no longer used as a census tract code for the 2010 Census.
