Great job handling a really complex dataset. I spot checked 2018, 2012 and 1999 files to make sure nothing was missing.

Approving because all my feedback won't affect the archives, and is mostly for clarity / legibility. (Presuming you'll check SAS files are downloaded as expected before you publish, that's the only thing that was missing when I ran this!)
