- The U.N. projects that the median age of the world’s population will increase from 23.6 years in 1950 to nearly 42 years by 2100.
- The pace of aging has risen substantially: It took 115 years for the 65+ year population to double in France (in 1984) and it will likely take 20 years for that doubling to happen in most countries in East Asia by 2030.
- A recent study estimates that an increase in the share of older workers by 1 percent is associated with a reduction in annual productivity by 0.2-0.6 percent in Europe and the U.S.
Should we fear population aging?

America’s demographic challenge
Quick, easy policy changes will not solve the problems of population ageing, high healthcare costs, and high inequality in maternal mortality and other health indicators in the US. Government and policymakers will likely need to address these challenges through large-scale social policy and health system reform. This will include a wider social safety net and better education for medical professionals, particularly about risk factors for expectant mothers and unconscious bias against historically marginalised populations, such as black women. A shrinking working population could also be supplemented by increased immigration of working-age adults to the US.
