Western Africa Population Pyramid 2031
Western Africa in 2031
By 2031, the population of Western Africa is expected to reach 529,976,438. Compared with 2021, when the projection stands at 426,042,566, that represents growth of 24.4% over ten years.
With a projected median age of 20.5 years, Western Africa would have a youth dependency ratio of 64.4 and an old-age dependency ratio of 5.6 per 100 people of working age. This is an expansive pyramid — each cohort of children is larger than the one above it, the signature of high birth rates and rapid growth.
