Charted: The Global Decline of Fertility Rates

Over the last 50 years, fertility rates have dropped drastically around the world. In 1952, the average global family had five children—now, they have less than three.

This graphic by Pablo Alvarez uses tracked fertility rates from Our World in Data to show how rates have evolved (and largely fallen) over the past decades.

What’s The Difference Between Fertility Rates and Birth Rates?

Though both measures relate to population growth, a country’s birth rate and fertility rate are noticeably different:

  • Birth Rate: The total number of births in a year per 1,000 individuals.
  • Fertility Rate: The total number of births in a year per 1,000 women of reproductive age in a population.

As such, the fertility rate is a more specific measure, which as Britannica highlights, “allows for more efficient and beneficial planning and resource allocation.” Not including immigration, a given area needs an overall total fertility rate of 2.1 to keep a stable population.

Global Fertility Rates since 1952

For the last half-century, fertility rates have steadily decreased worldwide. Here’s a look at the average number of children per woman since 1952:

Why are women having fewer children? There are a number of theories and empirical research studies to help explain this decrease, but according to Dr. Max Roser, the founder of Our World in Data, most of the literature boils down to three main factors:

  • Women’s empowerment, particularly in education and the workforce
  • Lower child mortality
  • Increased cost to raising children

Research has found that higher education in women is correlated with lower fertility. For instance, in Iran in the 1950s, women had an average of three years of schooling and raised seven children on average.

But by 2010, when Iranian women had nine years of schooling on average, the average fertility rate in the country had dropped to 1.8.

This theory is further supported when you look at countries where women’s education is still relatively lagging. For instance, in 2010, women in Niger had 1.3 years of education on average, and an average of more than seven children—more than double the global average at that time.

The Societal Impact

Lower fertility rates, coupled with increased life expectancies around the world, are creating an aging population. Since 1950, the global median age has grown from 25 years to 33 years.

An older population comes with a number of economic risks, including rising healthcare costs and a smaller global workforce.

share of population that's working age is shrinking

According to a report by the World Bank, the world’s working-age population peaked back in 2012. Since then, it’s been on the decline.

A smaller working population puts more pressure on those who are working to support those who are collecting pensions. This could ultimately lead to an economic slowdown if countries don’t prepare and alter their pension systems accordingly, to account for our aging population.

Charted: The World’s Biggest Oil Producers in 2022

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.

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.
