What About Dispersion Measures of Height

Scholars in recent years have researched heights of different populations, being dependent on the rare instances when a government recorded the heights of individuals and the records survived.  Economic historians have used the data to support hypotheses about the prosperity of societies at different times, on the theory that if height increases over time, it means the people are better fed and so can realize more of their genetic potential.

I find that interesting.  I may have mentioned previously on this blog occasions when I notice a group of individuals from different countries seeming to have the same height.  For example, soldiers in various Asian countries or dancers in different ballet groups. I'd add another group: Latino laborers in the US.  It seems these days most workers on road building/repairing or building construction are Latino, and visually there seems not be little variation in height.

I assume that the lack of variation reflects a restricted diet, that Latinos have  genes which would  permit same variability in height as other populations groups, given an abundant diet.  So with all that, I wonder whether any of the researchers have figured out the distribution of heights over the population.
