Answer :
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.
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.

Final answer:
The region with the lowest doubling times is North Asia, and the highest is Sub-Saharan Africa, with the replacement level for TFR being 2.1. Sub-Saharan Africa has the highest TFRs, while Eastern Asia and Europe have the lowest. High infant mortality is common in parts of Africa, contrasting with low rates in developed regions like North America and Western Europe.
Explanation:
The region with the lowest doubling times in the world is North Asia, while the region with the highest doubling times is Sub-Saharan Africa. The replacement level for total fertility rates (TFR) is 2.1, meaning on average, each woman needs to have approximately 2.1 children to replace herself and her partner, sustaining the current population level.
The regions with the highest total fertility rates are found in Sub-Saharan Africa, with countries like Niger having a TFR of around 7.0-7.9. In contrast, the lowest total fertility rates are observed in parts of Europe and Eastern Asia, where countries like Taiwan have TFRs as low as about 1.13. A region's fertility rates can significantly influence its population growth, reflecting economic development, healthcare accessibility, education, and cultural factors.
Countries with the highest infant mortality rates are located mainly in West Africa, East Africa, and South Africa, while the most significant decreases in infant mortality have occurred in North America and Western European countries. Places with low infant mortality rates typically offer better healthcare, social services, and a higher standard of living.
The lowest life expectancy rates are found in Southern Africa, influenced by various factors including health crises, economic instability, and social issues.
