Niger has one of the fastest-growing populations in the world, with a high fertility rate and rapid population growth. The country faces challenges in providing resources and services to its growing population.
Niger has the highest birth rate in Africa, with an average of over 7 children born per woman. This high birth rate can have significant implications for the country's population growth and development.
