Final answer:
The region with the lowest doubling times is North Asia, while Sub-Saharan Africa has the highest. The replacement level for total fertility rates is 2.1, indicating the average number of children a woman needs to have to replace herself and her partner. The highest total fertility rates are found in Sub-Saharan Africa and Southern Europe, while the lowest can be found in Greenland.
Step-by-step explanation:
The region with the lowest doubling times in the world is North Asia, while Sub-Saharan Africa has the highest. This means that the population of North Asia is growing at a slower rate compared to Sub-Saharan Africa.
The replacement level for total fertility rates is considered to be 2.1. This means that on average, each woman needs to have 2.1 children in order to replace herself and her partner. If the total fertility rate is below 2.1, the population will eventually start to decline.
The highest total fertility rates can be found in Sub-Saharan Africa and Southern Europe, while the lowest can be found in Greenland. This is because women in these regions are having more children in areas with high fertility rates and fewer children in regions with lower fertility rates.
