Other studies actually show slight overall height gains. Compare NHANES III (1988 - 94) HANES (1999 - 2000) and there is a 0.1" gain. I find that data from the New Yorker quite unbelievable, as the average height has been increasing http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5431a5.htm http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5431a5.htm , so how could there be "no subgroup that is getting taller"? I haven't taken math for a while, but that doesn't make sense.
The same article also reports: "Since the nineteen-twenties, the median height of Mexican-American teen-agers has nearly reached the United States’ norm. It’s that norm, and not the immigrants, that has failed to rise." So, you add a lot of people below the mean and wonder why the mean isn't rising?
