Answer :
Final answer:
Nigeria is recognized as Africa's most populous country with various estimates from different sources, but exceeding 181 million by 2015 and continuing to grow rapidly.
Explanation:
The African country with the largest population as of the year 2015 is Nigeria. While there are varying estimates of Nigeria's population from different organizations, it is widely recognized as the most populous nation in Africa.
The United Nations estimated the population to be at 114 million; the State Department had it at 120 million; the World Bank at 126.9 million; and the Central Intelligence Agency reported it at approximately 126,635,626. Additionally, by 2017, Nigeria's population had grown over 190 million and it is projected to become the third-most populous country in the world by 2050, surpassing the United States.
This growth trend reflects the overall population increase in Africa which crossed the 1 billion mark in 2015, as Sub-Saharan Africa alone has very high fertility rates and is seeing rapid population growth.
