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.

There may be errors! If something looks amiss, question it!

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!

Rough Plots

These are geneeral plots that aren't perfected every time the dataset is updated. All the data in these plots is in https://amiok.net/gitea/W1CDN/ham-radio-licenses/src/branch/main/data.
