179,7 cm as average in France, it seems too much.

and 182,5 cm for Netherlands, new reason to prove that people who are pretending to feel very short there are just lying or it's psychological. It's seems that biggest woman average is from Latvia with 169 cm as average (it's very big) and Netherlands for men with 182,5. In France, there was a big progression for male according to the website, but not for women. Women average is listed at 164,5.
According to Jean-Joseph Boillot, next economical desicions will influence french average.
According to Evelyne Heyer, the african average diversity is the biggest.

So now can you explain me how we can find some studies listing french people at 5'8"5 and some others (the latest) at 5'10"5 ?

I agree bofybuilder, but it's the same for Australiens and there is not 8 cm between french and dutch. It's too big
And 169 as woman average is really big, hard to imagine
