Global Fertility Rate Collapse Explained by Cultural Evolutionists

Cultural evolutionists have published only a modest number of models on the problem of declining fertility as populations develop. Global population growth peaked in the late 1960s with an average woman having 4.5 children, but fertility rates have been declining ever since. Birth rates are consistently falling faster than expected, and humans fail to correct for selection effects, leading to low fertility behavior being copied. The global fertility rate has collapsed, and this phenomenon has been explained.
