Which of the following best explains the high rate of population growth in West Africa?

The high rate of population growth in West Africa is best explained by the combination of high birth rate and low death rate. Birth rate refers to the number of births per 1,000 people in a population, while death rate refers to the number of deaths per 1,000 people in a population. In West Africa, the birth rate is high due to a number of factors, including a lack of access to family planning and birth control, cultural and religious beliefs that favor large families, and the role of children in providing labor and support for aging parents. At the same time, improvements in healthcare and sanitation have led to a decrease in the death rate, meaning that more people are surviving into adulthood and having children of their own. As a result, the population of West Africa has been growing rapidly, leading to a range of social, economic, and environmental challenges for the region.
