Show the answer
2.1 (answers within ±0.01 count)
Why
2.1. Two children replace two parents; the extra tenth covers girls who die before reaching childbearing age and the fact that around 105 boys are born for every 100 girls. In a high-mortality country the replacement figure is higher, sometimes well above 2.5.
