5.2.1 Natural increase of population
From Study Session 2 you will know that the population is increasing in developing countries. This natural increase is a significant cause of the growing urban population.
Explain what is meant by natural increase of population.
Natural increase of population occurs when the number of births exceeds the number of deaths.
As birth rates decline over time, according to the demographic transition model, the role of natural increase in determining the pace of urban population growth becomes less important in comparison to migration.
