Fertility Rate

            Fertility rate is the average number of children born to women during their reproductive period. In order for the population to remain stable in certain areas, a total fertility rate of 2.1 is required if it is assumed that there will be no immigration or emigration. Although the fertility rate in many parts of the world is far above the level of substitution, global efficiency has declined significantly since 1970. At this point, the TFR is around 4.5 in the world, but has dropped to 2 in 2015. 5. In the 21st century, industrialized countries generally have lower birth rates than developing countries, because the former has lower child mortality and better access to birth control. Higher birth rates in developing countries reflect the need for children to engage in agriculture and other economic activities and the lack of access to contraceptives. Total fertility rate (TFR), sometimes called fertility rate, absolute / potential birth rate, total fertility period (PTFR) or total fertility rate for the period (TPFR) of the population, is the average number of children born for a woman during her entire life.
