Charted: The World’s Aging Population from 1950 to 2100
As demographics continue to shift in the 21st century, the world’s aging population will continue to be a focal point for many global decision makers.
Most countries around the world have experienced population explosions, or are about to. Combine this with declining birth rates and falling mortality rates, and it’s clear that the global senior population will continue to reach new heights.
These graphics by Pablo Alvarez use data from the 2022 UN World Population Prospects to visualize this increasing aging population across countries.
The World’s Aging Population from 1950 to 2100
In 2022, there were 771 million people aged 65+ years globally, accounting for almost 10% of the world’s population.
This segment has been growing at an increasing rate, and it’s expected to hit 16% in 2050, and eventually 24% by 2100. Here’s what that’s projected to look like, for every country and territory.

Some of the places with high elderly shares today include high-income countries like Japan (30%), Italy (24%), and Finland (23%).
The lowest shares are concentrated in the Middle East and Africa. Many countries have just 2% of their population aged 65 years and older, such as Qatar, Uganda, and Afghanistan.
But over time, almost all countries are expected to see their older population segments grow. In just three decades, it is estimated that one-in-four European, North American, and Asian residents will be over 65 years of age.
By 2100, a variety of Asian countries and island nations facing low population growth are expected to see more than one-third of their populations aged 65 years or older, including South Korea and Jamaica at 44%. However, it’s actually Albania that’s the biggest outlier overall, with a projected 49% of its population to be aged 65 and older by 2100.
Passing the Generational Torch
The challenge of an aging population is set to impact all sectors of society, including labor and financial markets, demand for housing and transportation, and especially family structures and intergenerational ties.
One way to help grasp the nature of transition is to note the changing ratio between seniors and young children in the world population, as seen in the below crossover diagram:
Dropping fertility rates, in addition to improved child and infant mortality rates, are known to have played a major role in the plateauing population of children.
However, not all countries have witnessed this crossover yet, as it usually coincides with higher levels of economic development.
As countries such as India, Brazil, and South Africa reach higher levels of per capita income, they will be likely to follow down the paths of more advanced economies, eventually experiencing similar demographic fates and challenges.

- Cannabis is the world’s most widely used drug, with 244 million users in 2023.
- Three-quarters of users of cannabis, cocaine, or heroin are men, though women face higher health risks once they start using drugs.
Each year, hundreds of millions of people around the world use psychoactive substances. This chart breaks down the most widely used drugs globally, based on estimated users in 2023. The data shines a light on both the prevalence of use and the stark gender differences in drug-related harm.
The data for this visualization comes from the United Nations. It estimates the number of people worldwide who used selected drugs in the 12 months leading up to 2023.
Cannabis Remains the Most Popular Drug
With 244 million users globally, cannabis continues to dominate as the most commonly used drug. That’s nearly 80% of all drug users surveyed. The growing legalization movement in North America and parts of Europe may be driving its widespread use. According to Pew Research, support for legalization has surged, especially among younger generations.
| Drug | Estimated Users (Millions, 2023) |
|---|---|
| Cannabis | 244 |
| Opioids | 61 |
| Amphetamines | 31 |
| Cocaine | 25 |
| Ecstasy | 21 |
| Total | 316 |
Opioids: Fewer Users, Greater Risk
Opioids account for 61 million users—far fewer than cannabis—but are linked to significantly higher health risks and overdose deaths. Their addictive potential and impact on public health systems make them a critical focus. As WHO highlights, opioid-related deaths have been rising, especially in high-income countries where prescription abuse is prevalent.
Gender Disparities in Drug Use and Harm
Roughly three-quarters of users of cannabis, cocaine, or heroin are men. Yet once women initiate drug use, they are more susceptible to severe health outcomes.
According to the UN, women in general initiate drug use later in life than men, but once they do they tend to increase their consumption of different substances at a more rapid rate than men. Women also progress to drug use disorders at a more accelerated rate than men. In addition, women have a relatively higher risk of acquiring HIV and hepatitis C if they inject drugs.
