The single most important factor in population growth is the total fertility rate (TFR). If, on average, women give birth to 2.1 children and these children survive to the age of 15, any given woman will have replaced herself and her partner upon death. A TFR of 2.1 is known as the replacement rate. Total fertility rate (TFR) compares figures for the average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children according to a given fertility rate at each age. TFR is a more direct measure of the level of fertility than the crude birth rate, since it refers to births per woman. Fertility rate, total (births per woman) from The World Bank: Data.

Fertility rate and birth rate are both used to determine replacement rate of a country and are both factors in determining the development of countries. Fertility rate is the average number of children born women of the childbearing age (15-44 years). Birth rate is the number of lives births per 1,000 of the population each year. Although fertility rates remain well above the replacement rate in many parts of the world, the global TFR has declined significantly since 1970. At that time, the world’s TFR was roughly 4.5, but by 2015 it had dipped to 2.5. Replacement fertility is the total fertility rate at which women give birth to enough babies to sustain population levels. According to the UN Population Division, a total fertility rate (TFR) of about 2.1 children per woman is called replacement-level fertility. If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself.
In developed countries, replacement level fertility can be taken as requiring an average of 2.1 children per woman. In countries with high infant and child mortality rates, however, the average number of births may need to be much higher. Replacement level fertility is not associated with an unique set of age-specific birth rates. The concept of replacement rate is associated with total fertility rate. The replacement rate is the number of children each woman needs to have to maintain current population levels, or what is known as zero population growth, for her and the father. In developed countries, the necessary replacement rate is about 2.1. The world’s population will rise from just over 7 billion in 2012 to nearly 9.6 billion by 2050. Most of the world’s regions have already achieved or are close to achieving replacement level fertility. “Replacement level fertility” is the total fertility rate—the average number
