Airport Zip Codes Missing #1

Open maverick915 opened 2 years ago

maverick915 commented 2 years ago

Airport Zip Codes don't show up. Examples I've found are: 20041 30320 60666 30320 75261 55111 21240 20229 55605 96913 15231

Is there any way to get an updated list of zip codes?

I haven't had time to update this package, but will take a look at it this weekend or so, if you need an updated list, here is the US Census site including a list of files with updated data. https://www.census.gov/geographies/reference-files/time-series/geo/relationship-files.html, alternatively you could PR any updates and I'll gladly accept them.

It looks like the ZCTA's that are used by the US census are slightly different than actual Zip Codes and only include locations where people live (which makes sense since why would they do a census of Airports where people don't actually have a residence).

So other places like Airports won't be included in the ZCTA data. I did find another datasource at http://download.geonames.org/export/zip/ which has data focused more on actual zip codes. Of course it's in a different format and would require more changes.

Also the latest ZCTA data is available here: https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2022_Gazetteer/
