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:

Elderly population surpass that of children aged 5 and below

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.

Which Countries Have Universal Health Coverage?

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

According to the World Health Organization (WHO), Universal Health Coverage (UHC) means that everyone has access to a full range of health services—from emergency interventions to palliative care—without financial difficulty.

In this graphic, we use data from CEOWorld Magazine to visualize the countries that have UHC versus those that do not, along with how UHC coverage breaks down in terms of the global population.

The State of Universal Health Coverage in the World 

In 2024, 73 of the 195 countries worldwide had UHC, resulting in around 69% of the world’s population having some form of universal healthcare.

The United States is the only developed country without health coverage for all of its citizens.

As of 2022, the Census Bureau estimated that only 36.1% of Americans were covered by public health insurance. Private health insurance covered 65.6% of the population. This along with other facts has led the U.S. having the world’s highest healthcare spending figure per capita.

The History of Public Health Coverage

Germany was the first country to establish a social health insurance system. Launched in 1883, the program began by covering only blue-collar workers, then slowly expanded its net of those covered.

The first international declaration underlying the need for adequate health care was the Declaration of Alma-Ata in 1978 at the International Conference on Primary Health Care in 1978. The conference’s target was to achieve global UHC by 2000.

The Ottawa Charter for Health Promotion of 1986 also reiterated the “Health for All by the year 2000” goal, ultimately paving the way for more countries to adopt UHC.
