The way the buckets are structured over the years has changed.

Looking at the history of https://web.archive.org/web/20221003111240/https://www.bls.g... and the 15-xxxx set shows a change in how the BLS regarded the various fields. If you go far enough back, there were computer programmers, software developers (systems), and software developers (applications) as the three buckets.

The most interesting part (to me) has been how the web has been moved in and out of different buckets.
