Hi Richard,
Do you want to have the data structured so that each record is a unique combination of ZIP code, county and CD? We do not have a data file that provides information for that combination of geographic units.
It is possible to generate a dataset like that from the decennial census data. Census blocks will have codes for ZIP codes, counties and congressional districts. You can then collapse the data on those variables to create a file where each record is a unique combination of ZIP, county, and congressional district.
You wouldn’t be able to create that type of file for the American Community Survey because the ACS is not available for census blocks.
If you have questions about collapsing, let me know.
