A reader pointed me to the
Population Reference Bureau which has total fertility rates for women broken down by economic fifths. Unfortunately these data are limited to developing countries, but reader might be interested in any case. In no case do the women of the richest fifth have a higher fertility than the women in the poorest fifth.
