Understanding and Comparing Population Pyramids
Demographic data can reveal all kinds of insights about a population, from the country’s fertility and mortality rates to how certain events and policies have shaped the makeup of a population.
Population pyramids are one of the best ways to visualize population data, and comparing the pyramids of various countries and regions side-by-side can reveal unexpected insights and differences between groups.
This graphic uses population data from the United Nations to compare the demographics of some select nations and regions of the world, showcasing how much age distributions can vary.
Three Types of Population Pyramids
Although population pyramids can come in all shapes and sizes, most generally fall into three distinct categories:
- Expansive Pyramids: Recognized by their traditional “pyramid-like” shape with a broad base and narrow top, expansive pyramids reflect a population with a high birth rate along with a high mortality rate which is most common in developing countries.
- Constrictive Pyramids: With a narrow base and thicker middle and top sections of the pyramid, constrictive pyramids often occur in developed economies whose populations have low birth rates and long life expectancies.
- Stationary Pyramids: These pyramids showcase an evenly distributed population across age groups, often found in newly-developed countries which have stable birth and mortality rates.
Each population pyramid is essentially a visual snapshot of a nation’s current demographic breakdown, shaped by fluctuating birth and mortality rates as well as changes to immigration and social policies.
Understanding the inherent risks associated with different pyramid types can help give insight into the challenges these populations face.
The Risks of Different Population Pyramid Types
Each type of population pyramid structure has unique challenges and advantages often characterized by the country or region’s current stage of economic development.
Populations with expansive pyramids, such as the one representing the continent of Africa, have the advantage of a larger youth and working-aged population, however this advantage can be rendered null if job growth, education, and health care aren’t prioritized.
Countries with constrictive pyramids like Japan face the challenge of supporting their outsized aging population with a diminishing working-aged population. While immigration and increasing birth rates can help in both the short and long term, due to the working population being outnumbered, countries with constrictive pyramids must find ways to increase their productivity to avoid potential declines in economic growth.
China and India’s Demographics Compared
After the world’s population reached eight billion people last year, 2023 brought a new population milestone as India overtook China as the world’s most populous country.
When you compare the two nations’ population pyramids, you can see how India’s population has a strong base of young and working-aged people compared to China’s more constrictive population pyramid that also features a higher median age.
This demographic difference is largely shaped by China’s one-child policy which since 2021 was loosened to be a three-child policy. As a result, China’s total fertility rate is around 1.2 today, in contrast to India’s total fertility rate of 2.0.
While India is set to ride the productivity boom of its large working-age population, the country will have to ensure it can keep its population pyramid stable as the majority of the population ages and total fertility rates continue to decline.

Charted: The World’s Biggest Oil Producers
Just three countries—the U.S., Saudi Arabia and Russia—make up the lion’s share of global oil supply. Here are the biggest oil producers in 2022.
Charted: The World’s Biggest Oil Producers in 2022
In 2022 oil prices peaked at more than $100 per barrel, hitting an eight-year high, after a full year of turmoil in the energy markets in the wake of the Russian invasion of Ukraine.
Oil companies doubled their profits and the economies of the biggest oil producers in the world got a major boost.
But which countries are responsible for most of the world’s oil supply? Using data from the Statistical Review of World Energy by the Energy Institute, we’ve visualized and ranked the world’s biggest oil producers.
Ranked: Oil Production By Country, in 2022
The U.S. has been the world’s biggest oil producer since 2018 and continued its dominance in 2022 by producing close to 18 million barrels per day (B/D). This accounted for nearly one-fifth of the world’s oil supply.
Almost three-fourths of the country’s oil production is centered around five states: Texas, New Mexico, North Dakota, Alaska, and Colorado.
We rank the other major oil producers in the world below.

Behind America’s considerable lead in oil production, Saudi Arabia (ranked 2nd) produced 12 million B/D, accounting for about 13% of global supply.
Russia came in third with 11 million B/D in 2022. Together, these top three oil producing behemoths, along with Canada (4th) and Iraq (5th), make up more than half of the entire world’s oil supply.
Meanwhile, the top 10 oil producers, including those ranked 6th to 10th—China, UAE, Iran, Brazil, and Kuwait—are responsible for more than 70% of the world’s oil production.
Notably, all top 10 oil giants increased their production between 2021–2022, and as a result, global output rose 4.2% year-on-year.
Major Oil Producing Regions in 2022
The Middle East accounts for one-third of global oil production and North America makes up almost another one-third of production. The Commonwealth of Independent States—an organization of post-Soviet Union countries—is another major regional producer of oil, with a 15% share of world production.
| Region | 2022 Production (Thousand B/D) | YoY Change | Share of World Supply |
|---|---|---|---|
| Middle East | 30,743 | +9.2% | 32.8% |
| North America | 25,290 | +5.3% | 27.0% |
| CIS | 14,006 | +0.9% | 14.9% |
| Africa | 7,043 | -3.5% | 7.5% |
| Asia Pacific | 7,273 | -1.4% | 7.8% |
| South & Central America | 6,361 | 7.2% | 6.8% |
| Europe | 3,131 | -8.6% | 3.3% |
What’s starkly apparent in the data however is Europe’s declining share of oil production, now at 3% of the world’s supply. In the last 20 years the EU’s oil output has dropped by more than 50% due to a variety of factors, including stricter environmental regulations and a shift to natural gas.
Another lens to look at regional production is through OPEC members, which control about 35% of the world’s oil output and about 70% of the world’s oil reserves.
When taking into account the group of 10 oil exporting countries OPEC has relationships with, known as OPEC+, the share of oil production increases to more than half of the world’s supply.
Oil’s Big Balancing Act
Since it’s the very lifeblood of the modern economy, the countries that control significant amounts of oil production also reap immense political and economic benefits. Entire regions have been catapulted into prosperity and wars have been fought over the control of the resource.
At the same time, the ongoing effort to pivot to renewable energy is pushing many major oil exporters to diversify their economies. A notable example is Saudi Arabia, whose sovereign wealth fund has invested in companies like Uber and WeWork.
However, the world still needs oil, as it supplies nearly one-third of global energy demand.
