Woman
The total fertility rate (TFR) – the average number of children born to a woman over her lifetime — differs significantly between different regions of the world. In 2016, the highest estimated TFR was in Niger (6.62 children born per woman) and the lowest in Singapore (0.82 children/woman). While most Sub-Saharan African countries have a high TFR, which creates problems due to lack of resources and contributes to overpopulation, most Western countries currently experience a sub replacement fertility rate which may lead to population ageing and population decline.
