People who contribue more to society tend to have less kids than those who don't. If a woman becomes a doctor, lawyer, business woman, or other important job, compared to a other women she will not start a family until much later and not have as many kids. For people who contribute less to society, having kids can have an economic incentive, be it in the form child support or government aid.
