The trend changes the fertility rates and life expectancy, like in 1970s women had an average of 4.5 children each, but in 2014, total fertility rate had fallen to around 2.5 children per women. The seventh fold growth in a span of 200 years has been driven because of the increasing numbers of people surviving the reproductive age, accompanied by the changes in fertility rates, the total annual births were highest in the late 1980s at about 139 million and continued to be constant until 2011. It is observed that there is a continuing s growth since the end of the Black Death and great famine which claimed almost 370 million lives all over the world from years 1315-1350.
