We know that people have generally been getting taller (erm, OK, the average height of those alive has been rising, not that individuals necessarily grow) over the past century or so.
I’ve been looking around, but cannot find, a time series that tells me the average American height over that time.
I’ve a basic working assumption which is that something changed around 1980. Ish.
Very roughly indeed, the idea that being stunted by lack of childhood nutrition was something that stopped being a (widespread) problem in the US around or just after WWII. Mebbe a little later. Could even have been the War on Poverty etc of the 60s.
Given human lifespans this doesn’t start to feed through (sorry) into a change in the average heights of the population until the 80s and obviously it’s a continuing process still now.
It would also probably be best to have the data broken out by race: as average heights between races are very different and, say, Hispanic immigration might have kept the population average down but not the white/black or Hispanic.
So, does anyone know of such a time series? Average heights in the US by age/race post war?
The purpose is of course terribly flawed. There’s one statistic out there which changes significantly starting in the 1980s. What I’m trying to ponder is whether height explains that change…..
