The Asian countries are aging much faster that the United Stares

Japan has the highest old-age dependency ratio (the ratio of the population over 65 to the working age population aged 15-64) of any major economy in the world. Japan’s ratio was 48.8% in 2020 and is projected to increase by 59%, to reach 77.7% by 2050. This reflects Japan’s longstanding low fertility rates and high life expectancy.

South Korea is aging rapidly as well. Its old-age dependency ratio was 22.3% in 2020 and is forecast to increase by 258%, to 57.7% by 2050. Like Japan, low fertility and rising life spans are driving this.

China today is young. Its ratio is sa low at 17.8% in 2020, but that is set to climb by 274%, to 48.9% by 2050. This represents a huge demographic shift for the world’s most populous country.

Singapore had an old-age depndency ratio of 17.8% in 2020, projected to reach 60.4% in 2050. Singapore shares the challenge of low fertility and rising old-age ratios with its Asian peers.

The United States has much more favorable demographics, with an old-age dependency ratio of 25.5% in 2020, expected to rise by 38%, to 35.3% in 2050.. This is overwhelmingly due to the relatively young Hispanic population (median age 30) vs the entire population (38) and white population (44).

Canada is and will be more aged that of the U.S., from 33% by 72% to 57%.
