In January 2003 the Census 2000 population information was joined to the former stco coverage to create this stco data layer. Additional attributes included population in 1990 and 1980, and population change between each census.

Only Attributes were updated in 2003 with current census population data.
The Census Bureau cannot specify the accuracy of features inside of what was the 1980 GBF/DIME-File coverage or selected metropolitan areas. The Census Bureau added updates to the TIGER/Line files that enumerators annotated on maps sheets prepared from the Census TIGER data base as they attempted to traverse every street feature shown on the Census 2000 map sheets; the Census Bureau also made other corrections from updated map sheets supplied by local participants for Census Bureau programs. The locational accuracy of these updates is of unknown quality. In addition to the Federal, State, and local sources, portions of the files may contain information obtained in part from maps and other materials prepared by private companies. Despite the fact the TIGER/Line data positional accuracy is not as high as the coordinate values imply, the six-decimal place precision is useful when producing maps. The precision allows features that are next to each other on the ground to be placed in the correct position, on the map, relative to each other, without overlap.
County lines were taken from mylar USGS topoquads and other sources in 1987. The scale of the original data varies, relying primarily on 1:24,000 topoquads.. Boundary lines were checked against other boundary delineations such as Patton, Hagstrom, and county freeholder maps. Inconsistencies when found were evaluated and in many cases the Township Engineers were called or tax sheets viewed. Changes were made when inconsistencies with other maps were found based on preponderance of data. In area where the line was labeled as approximate, attempts were made to correctly locate the boundary. The 1986 photoquads were used to move the boundary lines to photo-identifiable features as needed. Changes of less than 5 acres were not made. This coverage was DISSOLVED from stmun.
US Census Bureau's census 2000 population tables were joined to existing county polygons in 2003.
