Synopsis ZIPFIP is both a set of databases containing census and locational information at the ZIP (ZIP code) and FIPS (county) level, and a program by which these data sets may be accessed and manipulated. It has several useful features, including: editing and displaying data; defining spatial boundaries known as market areas; determining distances between any two sites in the lower 48 States; and aggregating observations. ZIPFIP can extract commonly used census information by county or ZIP code, and correct for missing values.
