Zip Code Database Based on Census Data

I wanted a database of all zip codes in the country, with their lat & long. And I wanted it to be easy to import and easy to update.

I found this gist, which was great and did most of the hard work, but I wanted to:

1. Put the scripts in a single location
2. Have the database in dolthub for easy querying, updating, and sharing
3. Be able to easily update the zip code data

Formats

• JSON
• CSV
• CSV with PK ID
• SQL (mysql dialect)

Latest Zipcode Data

Where did this data come from?

• https://www.census.gov/geographies/reference-files/time-series/geo/gazetteer-files.html
• "ZIP Code Tabulation Areas"

This is documented in the bin/download-gazetteer script.

DoltHub

The data is available on Dolthub here:
