Introductory blog post: https://w1cdn.net/2024/01/us-ham-radio-license-counts-over-time/

This is a work in progress. It is not intended to be immediately useful for detailed analysis, but to act as a guide for further investigation. As we figure out how to slice up and caveat data, it will get more organized.

Contributing

I am trying to stage new data in the issues list, then copy that data into tabular format at a later date.

If you want to help, here are some ways:

• look at the issues and copy data into tabular format, share back in CSV format or pull request
• find new sources and create an issue for each new chunk of data (use best judgement)
• download data and QC: look for potential errors and inconsistencies, share those in a new issue
• download data and run analyses: share your interpretations
• choose your own way to contribute!
