I’ve continued playing with my collection of zip data files. I’ve now merged some 1999 data with 2000 data and I think I have a nice mix now. The 2000 data has (in my opinion) more realistic location data. While the 1999 data links up the zip code to the city, county, and state.

The kicker? Now you can look up zips and get population, housing, land area, and water area included in the results.
