Youngest States 2024

Youthful populations typically result from high fertility and birth rates. Additionally, aging populations go hand-in-hand with declining populations because birth rates are lower than death rates, and women have fewer babies.

A population’s age can affect several political, social, and cultural aspects. There is a fear that aging populations pose a threat to a society’s overall progress, as they could slow down productivity and innovation. Youthful populations are believed to have larger, more educated, and energetic workforces. This would increase economic productivity for a country or state. Additionally, it would create a larger tax base for the government, as more people would be in the workforce.
