Visualizing 200 Years of Systems of Government
Centuries ago, most of our ancestors were living under a different political paradigm.
Although democracy was starting to show signs of growth in some parts of the world, it was more of an idea, rather than an established or accepted system of government.
Even at the start of the 19th century, for example, it’s estimated that the vast majority of the global population — roughly 84% of all people — still lived under in autocratic regimes or colonies that lacked the authority to self-govern their own affairs.
The Evolution of Rule
Today’s set of charts look at global governance, and how it’s evolved over the last two centuries of human history.
Leveraging data from the widely-used Polity IV data set on political regimes, as well as the work done by economist Max Roser through Our World in Data, we’ve plotted an empirical view of how people are governed.
Specifically, our charts break down the global population by how they are governed (in absolute terms), as well as by the relative share of population living under those same systems of government (percentage terms).
Classifying Systems of Government
The Polity IV data series defines a state’s level of democracy by ranking it on several metrics, such as competitive and open elections, political participation, and checks on authority.
Polity scores are on a -10 to +10 scale, where the lower end (-10 to -6) corresponds with autocracies and the upper end (+6 to +10) corresponds to democracies. Below are five types of government that can be derived from the scale, and that are shown in the visualization.
- Colony
A territory under the political control of another country, and/or occupied by settlers from that country.
Examples: 🇬🇮 Gibraltar, 🇬🇺 Guam, 🇵🇫 French Polynesia - Autocracy
A single person (the autocrat) possesses supreme and absolute power.
Examples: 🇨🇳 China, 🇸🇦 Saudi Arabia, 🇰🇵 North Korea - Closed Anocracy
An anocracy is loosely defined as a regime that mixes democratic and autocratic features. In a closed anocracy, political competitors are drawn only from an elite and well-connected pool.
Examples: 🇹🇭 Thailand, 🇲🇦 Morocco, 🇸🇬 Singapore - Open Anocracy
Similar to a closed anocracy, an open anocracy draws political competitors from beyond elite groups.
Examples: 🇷🇺 Russia, 🇲🇾 Malaysia, 🇧🇩 Bangladesh - Democracy
Citizens exercise power by voting for their leaders in elections.
Examples: 🇺🇸 United States, 🇩🇪 Germany, 🇮🇳 India
A Long-Term Trend in Question
In the early 19th century, less than 1% of the global population could be found in democracies.
In more recent decades, however, the dominoes have fallen — and today, it’s estimated that 56% of the world population lives in societies that can be considered democratic, at least according to the Polity IV data series highlighted above.
While there are questions regarding a recent decline in freedom around the world, it’s worth considering that democratic governance is still a relatively new tradition within a much broader historical context.
Will the long-term trend of democracy prevail, or are the more recent indications of populism a sign of reversion?
Countries
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.
