- DTM stage 3 - The birth rate has lowered and the population is slowly growing. Most people are now living in cities.
- DTM stage 4 - The birth and death rate are equal so the population is stable.
- DTM stage 5 smaller families mean that the death rate is outweighing the birth rate. Population is slowly increasing.
