The issue of fertility among wealthy conservative and liberal white women was raised at Steve Sailer's blog. I calculated the mean number of children for the two groups (ages 40-59, households making at least 100k in 1986 dollars):
Mean number of offspring
Wealthy liberal women (n = 35) 1.60
Wealthy conservative women (n = 43) 2.49
The difference is statistically significant. Wealthy white conservative women average 55 percent more kids than their liberal counterparts.
