The FLDS site now includes a chart of the gender and ages of those taken in the raid.

Since this represents all of the children (or supposed children) in the YFZ ranch it is interesting to note the relative numbers of males and females. In the younger generation there are slightly more males, but in the teens there is an abnormally low number of males to the number of females than can realistically be explained by natural childbirth. What happened to the males? More lost boys?
