# Overview

Data and code for analysis at https://mastodon.radio/@W1CDN/111723969200676208.

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](https://amiok.net/gitea/W1CDN/ham-radio-licenses/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!

Add more data and update plots. Some plots modified a bit more than others. The stacked plot is a mess because of the different license classes, and the color-blind-friendly color scale breaks when there are too many colors. 2024-01-10 22:06:10 -06:00			`This is a work in progress.
