Epidemiologic Transition Model
A framework that analyzes the causes of death in different stages of a population's development
Stages of the Epidemiologic Transition Model
Stage 1: High mortality and fertility rates, primarily due to infectious diseases
Stage 2: Decrease in mortality rates, increase in fertility rates, and shift from infectious to chronic diseases
Stage 3: Continued decrease in mortality rates, increase in life expectancy, and shift to degenerative diseases
Stage 4: Low mortality and fertility rates, with a focus on degenerative diseases
Stage 5: Variants and differences in mortality rates and causes of death
