The old-age dependency ratio measures the number of people over the retirement age of 65 for every 100 working-age people. The lower the ratio, the more people there are supporting retirees, which translates to less fiscal strain on government systems.
In charts by creator Preyash Shad, we look at old-age dependency ratios of the top 10 economies based on data from the Organisation for Economic Co-operation and Development (OECD).
Japan in Trouble
Japan has had a rapidly rising old-age dependency ratio for several decades and has the highest ratio currently at 54.5.
Country | 2023 | 2050F |
---|---|---|
🇯🇵 Japan | 54.5 | 80.7 |
🇮🇹 Italy | 40.9 | 74.4 |
🇩🇪 Germany | 41.4 | 58.1 |
🇫🇷 France | 38.4 | 54.5 |
🇨🇳 China | 20.0 | 47.5 |
🇬🇧 United Kingdom | 34.2 | 47.1 |
🇨🇦 Canada | 33.4 | 44.9 |
🇺🇸 United States | 31.3 | 40.4 |
🇧🇷 Brazil | 17.1 | 39.5 |
🇮🇳 India | 11.6 | 22.5 |

Meanwhile, Germany is the runner-up in the top 10 economies with a distant second-place dependency ratio of 41.4.
At the same time, the United States maintains a relatively low old-age dependency, with a ratio of 31.3, which places it seventh among the top 10 economies.
India, now the world’s most populous country, has the lowest ratio of 11.6, in large part because it also has the youngest population.
Projections for 2050
By 2050, Japan will maintain the highest old-age dependency ratio of the group, moving from 54.5 to a staggering 80.7. In an effort to head-off such a high ratio, Japan is has put policies in pace to attract young immigrants and migrant workers and is making some progress.
Italy, which is facing similar demographic pressures, will move from distant third to a close second, moving from a ratio of 40.9 to 74.4.
China, because of the results of the one-child policy and low immigration, could surpass the U.S. by 2050 with a ratio of 47.5.

Key Takeaways
- India and China will likely remain the most populous countries till 2100.
- However several African countries will climb the ranks over the next few decades.
- These estimates come from the UN World Population Prospects 2024.
In 2023, India overtook China to lead the list of most populous countries in the world.
By looking at data on trends in fertility, deaths, and migration, the UN is able to project population figures for the world by the year 2100.
China Will Hold #2 Population Rank Despite Dramatic Fall
India is expected to retain it’s #1 ranking as the largest country by the end of this century.
Meanwhile, despite its population halving over the next 75 years, China is still expected to be the second-most populous country in 2100.

China’s projected population crash has garnered a lot of attention for the last decade. Enough of it for the country to remove it’s One Child Policy in an attempt to boost falling birth rates.
This nosedive will also change the shape of the Chinese population, with older adults outnumbering younger adults and children. This increases old-age dependency ratios that can put pressure on social systems like healthcare.
On the other hand, several African countries—including the DRC, Ethiopia, and Tanzania—are predicted to rapidly climb the most populous countries ranks after 2050.
Finally, based on current estimates, no country will cross the 1 billion mark again.
