While the overall population is expected to increase, the growth rate is estimated to decrease from 1.2 per cent per year in 2010 to 0.4 per cent per year in 2050. [30] The birth rate is also projected to decrease from 20.7 to 13.7, while the death rate is projected to increase from 8.5 in 2010 to 9.8 in 2050. [30]
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]
Rates are the average annual number of births or deaths during a year per 1,000 persons; these are also known as crude birth or death rates. Column four is from the UN Population Division [3] and shows a projection for the average natural increase rate for the time period shown using the medium fertility variant. Blank cells in column four ...
Replacement fertility is the total fertility rate at which women give birth to enough babies to sustain population levels, assuming that mortality rates remain constant and net migration is zero. [8] If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself. [8]
The under-five mortality rate (U5MR) per 1,000 live births decreased from 145.7 in 2007 to 100.2 in 2017. [5] When compared with other countries and global averages, Nigeria's health indicators remain poor. Life expectancy at birth in Nigeria. Top 10 causes of death in Nigeria (2007–2017)

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. [239] Nigeria's population increased by 57 million from 1990 to 2008, a 60% growth rate in less than two decades. [ 240 ]
