This led to more rural-urban migration in the newly liberated countries (Rakodi, 1997), and a stable decline in urbanization growth from 1950 to 1990 in South Africa. From figure 1 one can see that after the end of apartheid in 1990, the urbanization rate grow from 2.29% to 3.41%, while it continues to sink in the rest of Africa.

The first, urban population, describes the percentage of the total population living in urban areas, as defined by the country. The second measure, rate of urbanization, describes the projected average rate of change of the size of the urban population over the given period of time.
