In societies where women have limited access to education, they often marry young, usually for economic reasons, as seen in Mali. Early marriage leads to a longer amount of time where they can carry children, resulting in more children and higher birth rates. In contrast, in places where women are educated, they tend to marry later, often postponing marriage to pursue their academic goals, which reduces the number of children they have. Age is a key factor influencing fertility, as it determines the length of a woman's reproductive years and affects family planning decisions.
