Preference for large families continues to be a major factor determining levels of fertility in Sub-Saharan Africa. Recent data from DHS demonstrate reasons why men and women prefer and choose to have large families.
What is natural increase rate?
The rate of natural increase refers to the difference between the number of live births and the number of deaths occurring in a year, divided by the mid-year population of that year, multiplied by a factor (usually 1,000). It is equal to the difference between the crude birth rate and the crude death rate.
Is Africa’s population increasing?

What causes high natural increase rate?
The rate of population growth is the rate of natural increase combined with the effects of migration. Thus a high rate of natural increase can be offset by a large net out-migration, and a low rate of natural increase can be countered by a high level of net in-migration.
Why is natural increase rate important?
In demography, the rate of natural increase (RNI), also known as natural population change, is a statistic calculated by subtracting the crude death rate from the crude birth rate of a given region. This rate gives demographers an idea of how a certain country’s population is growing.
What affects natural increase rate?
The rate of natural increase (RNI) is a measure of how quickly a population is growing or declining. However, the RNI does not factor in population change resulting from immigration or emigration – it is determined solely by the difference between birth and death rates in a region.
