I'm looking for various sources (Global: US, UK, Europe) of adult height data. And it should be self-reported (meaning the person reports their own height, and not that a doctor measures them).
This question has a relevant answer on this forum: https://opendata.stackexchange.com/a/12085/1511
And the data even has a weird distribution (big bar at 182-185 cm, which contains 6 feet 0 inches):
and another one with two peaks
But I can't be sure it's self-reported.
