5 Fastest Aging Countries in the World

2. Japan

Demographic Old Age to Working Age Ratio: 80.0

With over one in ten people now exceeding 80 years old, Japan holds the world record for the oldest population. Recent data reveals that 29.1% of the country’s 125 million inhabitants are 65 or older, translating to roughly 36.23 million people. This trend is likely to continue due to a combination of low birth rates and a high life expectancy. Japan is at the second position on our list of the fastest aging countries in the world.
