What causes countries to have high and low crude birth rates?

High crude birth rates are often found in developing countries, where factors such as limited access to contraception, cultural norms favoring large families, and lower levels of education contribute to higher fertility rates. In contrast, low crude birth rates are typically observed in developed nations, where greater access to education, family planning resources, and career opportunities for women lead to smaller family sizes. Economic stability and urbanization also play significant roles, as people in urban settings may prioritize careers and personal development over having larger families. Additionally, societal shifts towards delayed marriage and childbearing further contribute to lower birth rates.
