Visualizing Population Decline by Country
Since the mid-1900s, the global population has followed a steep upwards trajectory.
While much of this growth has been concentrated in China and India, researchers expect the next wave of growth to occur in Africa. As of 2019, for example, the average woman in Niger is having over six children in her lifetime.
At the opposite end of this spectrum are a number of countries that appear to be shrinking from a population perspective. To shed some light on this somewhat surprising trend, we’ve visualized the top 20 countries by population decline.
The Top 20
The following table ranks countries by their rate of population decline, based on projected rate of change between 2020 and 2050 and using data from the United Nations.
|6||🇧🇦 Bosnia and Herzegovina||18.2%|
|18||🇲🇰 North Macedonia||10.9%|
Many of these countries are located in or near Eastern Europe, for reasons we’ll discuss below.
The first issue is birth rates, which according to the Peterson Institute for International Economics (PIIE), have fallen since the collapse of the Soviet Union. Across the region, the average number of children per woman fell from 2.1 in 1988 to 1.2 by 1998.
Birth rates have recovered slightly since then, but are not enough to offset deaths and emigration, which refers to citizens leaving their country to live elsewhere.
Eastern Europe saw several waves of emigration following the European Union’s (EU) border expansions in 2004 and 2007. The PIIE reports that by 2016, 6.3 million Eastern Europeans resided in other EU states.
There are two geographical outliers in this dataset which sit on either side of Europe.
The first is Japan, where birth rates have fallen continuously since 1970. It wasn’t until 2010, however, that the country’s overall population began to shrink.
By the numbers, the situation appears dire. In 2021, 811,604 babies were born in Japan, while 1.44 million people died. As a result of its low birth rates, the island nation also has the world’s highest average age at 49 years old.
The Japanese government has introduced various social programs to make having kids more appealing, but these don’t appear to be getting to the root of the problem. For deeper insight into Japan’s low birthrates, it’s worth reading this article by The Atlantic.
The second country is Cuba, and it’s the only one not located within the Eastern Hemisphere. Cuba’s fertility rate of 1.7 children per woman is the lowest in the Latin American region. It can be compared to countries like Mexico (2.2), Paraguay (2.5), and Guatemala (3.0).
Cuba’s immigration is also incredibly low compared to its neighboring countries. According to the International Organization for Migration, immigrants account for just 0.1% of its total population.
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.
|YoY Change||Share of
|2||🇸🇦 Saudi Arabia||12,136||+10.8%||12.9%|
|36||🇸🇸 South Sudan||141||-7.6%||0.2%|
|51||Other Middle East||210||+1.2%||0.2%|
|54||Other Asia Pacific||177||-10.6%||0.2%|
|55||Other S. &|
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.

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.
