Visualized: The World’s Population at 8 Billion

At some point in late 2022, the eight billionth human being will enter the world, ushering in a new milestone for humanity.

In just 48 years, the world population has doubled in size, jumping from four to eight billion. Of course, humans are not equally spread throughout the planet, and countries take all shapes and sizes. The visualizations in this article aim to build context on how the eight billion people are distributed around the world.

Now, here’s a look at each country’s population as of September 2022:

Below are regional breakdowns of population.

Africa’s Population by Country

As of 2022, Africa’s total population stands at 1.4 billion people. Many of the countries with the fastest growth rates are located in Africa and by 2050, the population of the continent is expected to jump to 2.5 billion.

Nigeria is Africa’s most populous country and its largest economy. Based on current growth rates, Nigeria’s largest city, Lagos, could even emerge as the world’s top megacity by the end of the century.

Africa has by far the lowest median age of any of the other continents.

Asia’s Population by Country

With 4.7 billion people in 2022, Asia is by far the world’s most populous region.

The continent is dominated by the two massive population centers of China and India. In 2023, a big shift will occur, with India surpassing China to become the world’s most populous country. China has held top spot for centuries, but the mismatch between the two countries’ growth rates made it only a matter of time before this milestone arrived.

Asia is a region of contrast when it comes to population growth. On the one end are countries like Singapore and Japan, which are actually shrinking. On the other, are Middle Eastern nations like Oman and Qatar, which have robust population growth rates of 4-5%.

Vietnam is on the cusp of becoming the 15th country to surpass the 100 million population mark.

Europe’s Population by Country

Europe’s population in 2022 is 750 million people—more than twice the size of the United States.

A century ago, Europe’s population was close to 30% of the world total. Today, that figure stands at less than 10%. This is, in part, due to population growth throughout other regions of the world.

More importantly though, Europe’s population is contracting in a number of places—Eastern Europe in particular. Many of the countries with the slowest growth rates are located in the Balkans and former Soviet Bloc countries.

Russia remains Europe’s largest country by population. Although the country’s landmass extends all the way across Asia, three-quarters of Russia’s people live on the European side of the country.

Germany is the second largest country in Europe, followed by the UK, France, and Italy.

Ukraine is the seventh largest population center in Europe, but it remains to be seen how the current conflict with Russia impacts the country’s long-term population prospects.

North America’s Population by Country

North America’s population is 602 million people as of 2022.

The continent is dominated by the United States, which makes up more than half of the total population. America’s population is still growing modestly (by global standards), but perhaps more interesting are the internal migration patterns that are occurring. States like Texas and Florida are seeing an influx from other states.

Canada has one of the highest population growth rates of major developed economies thanks to international migration.

Mexico is currently the 10th most populous country, but will eventually be bumped from the top 10 list by fast-growing African nations.

South America’s Population by Country

The population of South America in 2022 is 439 million. Brazil makes up nearly half of that total.

Sometime this decade, Colombia’s capital, Bogotá, will become the region’s fifth megacity (which is defined as having a population of 10 million or more). São Paulo, Rio de Janeiro, Buenos Aires, and Lima are South America’s current megacities.

Oceania’s Population by Country

The population of the Oceania region is 44 million people—just slightly higher than the population of California.

Australia, New Zealand, and Papua New Guinea make up the lion’s share of the population of this region.

Interestingly, many of the smallest countries by population can also be found in this region.

When Will Earth’s Population Hit 9 Billion?

The next global population milestone—nine billion—will likely be hit sometime in the 2030s.

In fact, Earth’s population is expected to continue growing until it hits a peak at some point in the 2080s—possibly over the 10 billion mark.

The Biggest Tech Talent Hubs in the U.S. and Canada

The tech workforce just keeps growing. In fact, there are now an estimated 6.5 million tech workers between the U.S. and Canada — 5.5 million of which work in the United States.

This infographic draws from a report by CBRE to determine which tech talent markets in the U.S. and Canada are the largest. The data looks at total workforce in the sector, as well as the change in tech worker population over time in various cities.

The report also classifies which metro areas and regions can rightly be considered tech hubs in the first place, by looking at a variety of factors including cost of living, average educational attainment, and tech employment levels as a share of different industries.

The Top Tech Hubs in the U.S.

Silicon Valley, in California’s Bay Area, remains the most prominent (and expensive) U.S. tech hub, with a talent pool of nearly 380,000 tech workers.

Here’s a look at the top tech talent markets in the country in terms of total worker population:

America’s large, coastal cities still contain the lion’s share of tech talent, but mid-sized tech hubs like Salt Lake City, Portland, and Denver have put up strong growth numbers in recent years. Seattle, which is home to both Amazon and Microsoft, posted an impressive 32% growth rate over the last five years.

Emerging tech hubs include areas like Raleigh-Durham. The two cities have nearly 70,000 employed tech workers and a strong talent pipeline, seeing a 28% increase in degree completions in fields like Math/Statistics and Computer Engineering year-over-year to 2020. In fact, the entire state of North Carolina is becoming an increasingly attractive business hub.

Houston was the one city on this list that had a negative growth rate, at -2%.

The Top Tech Hubs in Canada

Tech giants like Google, Meta, and Amazon are continuously and aggressively growing their presence in Canada, further solidifying the country’s status as the next big destination for tech talent. Here are the country’s four tech hubs with a total worker population of more than 50,000:

Toronto saw the most absolute growth tech positions in 2021, adding 88,900 jobs. The tech sector in Canada’s largest city has seen a lot of momentum in recent years, and is now ranked by CBRE as North America’s #3 tech hub, after the SF Bay Area and New York City.

Vancouver’s tech talent population increased the most from its original figure, climbing 63%. Seattle-based companies like Microsoft and Amazon have established sizable offices in the city, adding to the already thriving tech scene. Furthermore, Google is set to build a submarine high-speed fiber optic cable connecting Canada to Asia, with a terminus in Vancouver.

Not to be left behind, Ottawa has also taken giant strides to increase their tech talent and stamp their presence. The country’s capital even has the highest concentration of tech employment in its workforce, thanks in part to the success of Shopify.

The small, but well-known tech hub of Waterloo also had a very high concentration on tech employment (9.6%). The region has seen its tech workforce grow by 8% over the past five years.

Six out of the top 10 cities by tech workforce concentration are located in Canada.

Evolution of Tech Hubs

The post-COVID era has seen a shifting definition of what a tech hub means. It’s clear that remote work is here to stay, and as workers migrate to chase affordability and comfort, traditional tech hubs are seeing some decline — or at least slower growth — in their population of tech workers.

While it isn’t evident that there is a mass exodus of tech talent from traditional coastal hubs, the rise in high-paying tech jobs in smaller markets across the country could point to a trend and is positive for the industry.

While more workers with great talent, resources, and education continue to opt for cost-friendly places to reside and work remotely, will newer markets like Charlotte, Tennessee, and Calgary see a rise of tech companies, or will large corporations and startups alike continue to opt for the larger cities on the coast?
