Women in cities less likely to have children

A Finnish study analyzed the reproductive histories of women who moved from rural to urban areas during WWII and found that urban women were 15% less likely to reproduce than their rural counterparts. The study suggests that women may be delaying childbearing due to increased competition for spouses in urban environments.
