A (very) brief exploratory analysis of NLSY97 height data

The NLSY97 data provides height information for both biological parents and students at yearly intervals, so I thought I’d take a look at that data.


It looks very much like heritability increases with age here (unsurprisingly).  Around age 13 the slope is relatively flat, especially for boys, but it slowly increases and by age 21 (give or take) there is a rather stark contrast.
