The global population pyramid: How global demography has changed and what we can expect for the 21st century
In 1950, there were 2.5 billion people on the planet. In 2021, there were around 8 billion. By the end of the century, the UN expects a global population of around 10 billion. But how has the age structure of the world’s population changed over time? The following chart — the population pyramid — makes it possible to understand this enormous global transformation. Population pyramids visualize the demographic structure of a population. The width represents the size of the population of a give...
The median age provides an important single indicator of the age distribution of a population. It provides the age 'midpoint' of a population — where there are the same number of people who are older than the median age as there are younger than it. On the map, we see the median age in all countries in the world. Overall we see that higher-income c...
The age structure of a population has important impacts for various aspects of society: economic growth rates, labour force participation, educational and healthcare services, housing markets amongst others.2,3 Over the past century, the age structure of populations has been changing dramatically. In these two charts you can compare the population ...
The world population is changing: For the first time there are more people over 64 than children younger than 5
Countries across the world have been going through an important demographic transition: from young to increasingly aging populations. In 2018, the number of people worldwide older than 64 years old surpassed the number of children under 5 years old. This was the first time in history this was the case.4 We can see this transition clearly when we look at the population by age bracket in the chart — this is shown from 1950 onwards, with UN projections to 2100. In this chart, you can explore the...
It is common in demography to split the population into three broad age groups: 1. children and young adolescents (under 15 years old) 2. the working-age population (15–64 years) and 3. the elderly population (65 years and older) A large share of the population in the working-age bracket is seen as essential to maintain economic and social stabilit...

Introduction. The median age in the world has been increasing steadily over time, driven largely by longer life expectancy and declining fertility rates. Currently, the world’s median age is estimated to be around 30 years old; however, this figure varies substantially from country to country.
› Population. › Median Age. Global Median Age. The world's population median age continues to increase, due to an ageing population and declining birth rates. In 2024, the global median age is recorded at 30.7 years of age. A 0.81% increase from 2023, when the population median age only was 30.5 years.
May 29, 2023 · 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%.
In 2021, the global average life expectancy was just over 70 years. This is an astonishing fact – because just two hundred years ago, it was less than half. This was the case for all world regions: in 1800, no region had a life expectancy higher than 40 years. The average life expectancy has risen steadily and significantly across all regions. 1
