Coale and Treadway Model
The Coale and Treadway Model analyzes how a population’s birthrate responds to factors like marriage patterns, economic conditions, and women's health. It predicts fertility rates by examining three key "control factors": the proportion of women married, their likelihood of conceiving, and their duration of reproductive years. The model helps explain why fertility varies across societies and times, emphasizing that individual decisions about having children are influenced by social and economic contexts. It provides a framework for understanding and forecasting population growth based on these adaptive reproductive behaviors.
