The data is most likely skewed because of inherent errors in the
"license census" tally.

JS, there is no "census" of numbers on the www.hamdata.com site.
They take their data download from the FCC's huge amateur radio
database file and sort that. That's what the ARRL does, that's what
QRZ does, that's what everyone else does.

The FCC database has specific fields indicating who is NEW and
the duration of all granted licensees. Adding two years to the
given expiration date is a trivial program task. The two years are
for the grace period.

The FCC does the record keeping for the licenses the FCC grants.

No "baby boom" enters this simple picture of numbers, no inferences.

There are just licensees in the U.S. amateur radio service.
