The demographic transition model shows lines for birth rate, death rate and total population over five developmental stages.
The graphic shows DTM stage 1 (high fertility and mortality, stable population), DTM stage 2 (dropping fertility and high mortality, increasing population), DTM stage 3 (lower fertility and dropping mortality, slowing population), DTM stage 4 (low fertility and mortality, stable population), and DTM stage 5 (low fertility and mortality, potentially shrinking population).
Read more about the model, features of each stage, and case studies of countries in each DTM stage in our popular DTM blog series.
