> poor people in developed countries and poor people in undeveloped countries have much higher fertility rates.
There can be a whole lot of reasons for that.
poorer people are more likely to be uneducated, have less access to contraception.
Poor people have higher infant mortality.
Children also make people poorer. the higher the fertility rate the more likely that someone will be poor.
Poorer people also tend to be more religious which can limit women's rights, their options, and increase the expectations placed on them when it comes to having children. That's especially true in undeveloped countries where women may have no choice at all.
