Nigeria's population has been increasing rapidly for at least the last 5 decades due to very high birth rates, quadrupling its population during this time. Growth was fastest in the 1980s, after child mortality dropped rapidly.
Crude birth rate refers to the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as number of births per 1,000 population. The article lists 233 countries and territories in crude birth rate. The first list is provided by Population Reference Bureau. [1]
The birth rate is 35.2-births/1,000 population and the death rate is 9.6 deaths/1,000 population as of 2017, while the total fertility rate is 5.07 children born/woman. [229] Nigeria's population increased by 57 million from 1990 to 2008, a 60% growth rate in less than two decades. [230]
The replacement fertility rate is 2.1 births per female for most developed countries (in the United Kingdom, for example), but can be as high as 3.5 in undeveloped countries because of higher mortality rates, especially child mortality. [11]

[2] [3] Total population as of 2024 is about 1.5 billion, [4] with a growth rate of about 100 million every three years. The total fertility rate (births per woman) for Africa is 4.1 as of 2024, the highest in the world. [5] The most populous African country is Nigeria with over 206 million inhabitants as of 2020 and a growth rate of 2.6% p.a. [6]
This is a list of countries showing past fertility rate, ranging from 1950 to 2015 in five-year periods, as estimated by the 2017 revision of the World Population Prospects database by the United Nations Population Division. The fertility rate equals the expected number of children born per woman in her child-bearing years.
The policy is built on top of the background of Nigeria's sustained high fertility rate. To reverse it, the policy plans to increase access to modern family planning methods, birth spacing, and counseling. The outcome of the policy is improvement in women's health, newborns, children, and adolescents. [16] [17] [18]
