Animation: U.S. Population Pyramid From 1980-2050
It’s no secret that an aging population will be the source of major demographic challenges in the coming years.
In 1975, the median age in the United States was just 28 years old. However, it’s been rising fast as the Baby Boomers age, and it’s expected to break the 40 year mark by 2030.
This shift is so fundamental that its ripples will be felt in almost every area imaginable. How we manage this change will have implications on the economy, culture, and politics – and it will almost certainly affect our personal wealth and investments, as well.
Visualizing Age in the U.S.
We’ve previously compared the population pyramids of China and India, but today we’re going to key in on the U.S. using a similar type of animation.
Below is an animated population pyramid that shows how the U.S. population has been shifting, including projections up until 2050 based on data from the U.S. Census Bureau and World Bank.

By 2050, the U.S. population will close in on 400 million people.
As with most demographic data, viewing changes in the composition of this population through a visual lens helps to provide perspective.
One of the biggest differences in this particular chart can be seen in the 65+ year region. In the 1980s, only a small portion of the population fits there – but by the end, it’s becoming quite crowded.
In more numerical terms – the number of Americans aged 65+ is projected to jump from 46 million today to over 98 million by 2060, and the 65+ age group’s share of the total population will rise to nearly 24%. This is mainly a function of a big generation (Baby Boomers) hitting their later years, and improved life expectancy and healthcare.
According to the Population Reference Bureau, aging Baby Boomers could mean a massive 75% increase in number of Americans requiring nursing home care, from 1.3 million in 2010 to 2.3 million in 2030.
Social Security and Medicare expenditures will also increase from 8% to 12% of GDP by 2050.
Another factor in the population equation is also lower fertility rates.
U.S. Fertility Rate (births per woman)
In the United States, the fertility rates that led to the Baby Boomer generation (born 1946-1964) have been long-gone for many decades now.
Lately, fertility has been hovering closer to 1.8 births per woman.
For reference, the replacement fertility rate is about 2.1 – meaning that without taking into account net immigration, each new generation will be smaller than the last. Unless something changes here (or with immigration policy), a more mature population will increasingly become the norm for the country.
Charted: The Number of Democracies Globally
How many democracies does the world have? This visual shows the change since 1945 and the top nations becoming more (and less) democratic.
Charted: The Number of Democracies Globally
The end of World War II in 1945 was a turning point for democracies around the world.
Before this critical turning point in geopolitics, democracies made up only a small number of the world’s countries, both legally and in practice. However, over the course of the next six decades, the number of democratic nations would more than quadruple.
Interestingly, studies have found that this trend has recently reversed as of the 2010s, with democracies and non-democracies now in a deadlock.
In this visualization, Staffan Landin uses data from V-DEM’s Electoral Democratic Index (EDI) to highlight the changing face of global politics over the past two decades and the nations that contributed the most to this change.
V-DEM’s EDI attempts to measure democratic development in a comprehensive way, through the contributions of 3,700 experts from countries around the world.
Instead of relying on each nation’s legally recognized system of government, the EDI analyzes the level of electoral democracy in countries on a range of indicators, including:
- Free and fair elections
- Rule of law
- Alternative sources of information and association
- Freedom of expression
Countries are assigned a score on a scale from 0 to 1, with higher scores indicating a higher level of democracy. Each is also categorized into four types of functional government, from liberal and electoral democracies to electoral and closed autocracies.
Which Countries Have Declined the Most?
The EDI found that numerous countries around the world saw declines in democracy over the past two decades. Here are the 10 countries that saw the steepest decline in EDI score since 2010:
|Country||Democracy Index (2010)||Democracy Index (2022)||Points Lost|
Central and Eastern Europe was home to three of the countries seeing the largest declines in democracy. Hungary, Poland, and Serbia lead the table, with Hungary and Serbia in particular dropping below scores of 0.5.
Some of the world’s largest countries by population also decreased significantly, including India and Brazil. Across most of the top 10, the “freedom of expression” indicator was hit particularly hard, with notable increases in media censorship to be found in Afghanistan and Brazil.
Countries Becoming More Democratic
Here are the 10 countries that saw the largest increase in EDI score since 2010:
|Country||Democracy Index (2010)||Democracy Index (2022)||Points Gained|
|🇬🇲 The Gambia||0.25||0.50||+25|
|🇱🇰 Sri Lanka||0.42||0.57||+15|
Armenia, Fiji, and Seychelles saw significant improvement in the autonomy of their electoral management bodies in the last 10 years. Partially as a result, both Armenia and Seychelles have seen their scores rise above 0.5.
The Gambia also saw great improvement across many election indicators, including the quality of voter registries, vote buying, and election violence. It was one of five African countries to make the top 10 most improved democracies.
With the total number of democracies and non-democracies almost tied over the past four years, it is hard to predict the political atmosphere in the future.
