I notice that you sell a package for all congressional districts. How much is it for a single district? [b]Answer[/b]: We do not sell individual district files. The user must create the desired district by combining the appropriate zip codes/counties. All zip codes for a county can be purchased by buying the "county plus package". Note, it is possible to combine county files with the zip code files. Some districts, like WY district 1, is simply the state totals file. The most recent public source for district zips and counties (that I found) is for the 110th Congress: http://www.census.gov/geo/www/cd110th/tables110.html The current, 112th congress, districts should only be slightly, if at all, different as they both based on the 2000 Census and the major redistricting occurred before the 110th Congress.
