Rapid population growth decreases the efficiency of purifying selection.
Doesn’t that depend on how uniform the growth is? If a third of women have 0, 2, and 4 children respectively, then I would expect the genes that put you in the most fertile group to spread more slowly (in both relative and absolute terms) than under conditions where a third of women have 0, 3, and 9 children respectively.
