What is a TIGER Line File?

“The U.S. Census Bureau produces road data, or a ‘centerline’ file, for each county in the United States that is publicly available at no fee as part of their TIGER (Topologically Integrated Geographic Encoding and Referencing System) Line Files. Because these files are developed at the federal level rather than locally, there can be many discrepancies such as slight errors, missing records, and improper attribution. Also, this data is not updated very frequently, so the files aren’t always current. However, it is important to note that the U.S. Census Bureau has a TIGER Modernization Program underway that will address most of these issues starting with the 2010 dataset. More information about TIGER can be accessed at http://www.census.gov/geo/www/maps/.
