In any given country, an aging population often means workers will be retiring faster than job vacancies can be filled by those entering the labor force. As retirement-age populations grow, health care and pension systems are strained — not only by rising demand for benefits and services, but also by the smaller pool of workers paying into social safety net programs.
Using data from the World Bank, 24/7 Wall St. identified the countries that are aging the fastest. Countries are ranked on the percentage point change in the share of the population aged 65 and up between 2003 to 2022. Data on median age by country is from the CIA World Factbook and is for the most recent available year. All other supplementary data is from the World Bank and is also for the most recent available year.
Why It Matters

Demographic trends, like an aging population, can have far-reaching consequences. In any given country, more older residents can mean fewer people to fill essential jobs, and fewer workers to support a growing number of retirees. The problem is expected to get worse before it gets better. There were over 700 million people aged 65 and older worldwide in 2020, and according to U.N. estimates, that number is expected to double by mid-century.
