Bongaarts model
The Bongaarts model is a framework used to understand how various factors influence population growth. Developed by demographer William Bongaarts, it identifies four main components: the level of fertility, mortality rates, age structure of the population, and migration. By analyzing these elements, the model helps researchers and policymakers predict changes in population size and structure over time. It emphasizes that fertility and mortality are key determinants of population dynamics, guiding decisions on health, resource allocation, and social services in a community.

The Bongaarts Model is a framework used in demography to understand how different factors affect population growth. It breaks down the relationship between fertility and population changes into four key components: the desired number of children, the proportion of women of childbearing age, the contraceptive use, and the age at which women have children. By analyzing these factors, demographers can predict how populations will grow or decline, providing valuable insights for policymakers planning for future social and economic needs. Essentially, it helps explain how choices around family size and reproductive health shape population trends.
