Explain why despite a high infant mortality rate, the population of South Africa and Tanzania show high levels of natural increase?

High Fertility Rates: Both South Africa and Tanzania have high fertility rates. This means that on average, women in these countries have more children than women in many other parts of the world. Even with a high infant mortality rate, the sheer number of births can lead to a net population increase.

Young Population: Both countries have a relatively young population. This means that a large proportion of the population is in their childbearing years, which can lead to high levels of natural increase.

Decreasing Mortality Rates: While the infant mortality rate may be high, it's important to note that overall mortality rates (including adult mortality rates) may be decreasing due to improvements in healthcare, nutrition, and living conditions. This can contribute to population growth.

Migration: Migration can also affect population growth. If a country has a net inflow of people (more people immigrating to the country than emigrating), this can contribute to population growth.

Cultural Factors: Cultural and societal norms can also play a role. In many societies, having many children is seen as desirable or advantageous. This can contribute to high fertility rates and population growth.

Lack of Access to Family Planning: In many parts of South Africa and Tanzania, access to family planning services may be limited. This can result in higher fertility rates and population growth.
