Disclosure  
Description TIGER/Line Files are extracts of selected geographic and cartographic information from the US Census Bureau's Master Address File (MAF)/Topologically Integrated Geographic Encoding and Referencing (TIGER) system. Before 2007 these were constructed of ZIP files containing ASCII data. Each ZIP represents a single county or equivalent. Each ZIP contains a number of 'Record Type' files. In the 2000 Census data there were up to 17 Record Type files per ZIP, with each named RTx where x represents a value for the nature of the Record Type, so e.g. Record Type 1 = <filename>.RT1, Record Type Z = <filename>.RTZ. In the 1992 Census data the internal files had an .F5x extension, where x represents the value for each record type.
