During the same period,
Americans expanded horizontally but not vertically . The average height of the
American male today is stuck at 5 feet 9 1/2 inches. U.S.
women have actually lost a third of an inch and are on average slightly over 5 foot 4.
I have to disagree with you on this. My oldest nephew who turned 12 in April is currently 5'8" and still growing. My youngest niece Mia at age 2 is 3'2". Many people I know who have children, their children are growing like weeds too. I know few teenagers who are quite tall for their age as well. Those teens that I know, girls are anywhere from 5'6" to 5'9" and the boys are 6 ft and taller.
(I see this in the area where I live) However, I will agree that many American's (many children) have grown
sideways within the last decade or so. Which is quite disturbing.
