Studying the orange line, you observe that until 1975-80 some countries substantially lower their unique virility:

Asia’s fertility rate dropped to 3 (this is mostly vendor launch with the ‘one kid approach’). Or countries maintained extremely high fertility degree. In Yemen, the virility rate am 8.9 offspring per girl in the year 1985. The global ordinary had been nearly 4 young ones per woman.
