Good news: Using GSS data, I looked at the number of children for white women ages 40-49 averaged over the nineties, and then in this decade:
IQ Group/Mean kids this decade/Change over the past decade
High IQ--(1.82) up .23
Medium IQ--(2.07) up .08
Low IQ--(2.00) down .17
The high-IQ group (those scoring 8, 9, or 10 out of ten on a vocabulary test) averaged 1.82 kids this decade which is up .23 over the 1990s. The medium-IQ group (5 through 7 on the test) have had 2.07 kids, .08 higher than last decade. The low-IQ group (0 through 4 on the test) came down from 2.17 in the 1990s to 2.00 in this decade.
In other words, things have improved a lot in only 10 years. I know, I know that mean white IQ is not going up as a result, but I still like it.
