The largest portion of elderly in 2030 will be in the country of what because of low birth rates and rising life expectancies.

The largest portion of elderly individuals by 2030 is expected to be in Japan. This trend is largely due to two significant factors: low birth rates and increasing life expectancy.

Japan has one of the lowest birth rates in the world, which means that fewer young people are being born to replace the aging population. Concurrently, advancements in healthcare, nutrition, and overall living conditions have led to a significant increase in life expectancy, allowing more individuals to live longer lives. As a result, the demographic composition is shifting towards a higher proportion of elderly individuals compared to the younger population.

This change poses challenges for the country in terms of social support systems, healthcare services, and economic productivity, as a larger elderly population may require more resources and care.
