How Global Health and Wealth Has Changed Over 221 Years
At the dawn of the 19th century, global life expectancy was only 28.5 years.
Outbreaks, war, and famine would still kill millions of people at regular intervals. These issues are still stubbornly present in 21st century society, but broadly speaking, the situation around the world has vastly improved. Today, most of humanity lives in countries where the life expectancy is above the typical retirement age of 65.
At the same time, while inequality remains a hot button topic within countries, income disparity between countries is slowing beginning to narrow.
This animated visualization, created by James Eagle, tracks the evolution of health and wealth factors in countries around the world. For further exploration, Gapminder also has a fantastic interactive chart that showcases the same dataset.
The Journey to the Upper-Right Quadrant
In general terms, history has seen health practices improve and countries become increasingly wealthy–trends that are reflected in this visualization. In fact, most countries drift towards the upper-right quadrant over the 221 years covered in the dataset.
However, that path to the top-right, which indicates high levels of both life expectancy and GDP per capita, is rarely a linear journey. Here are some of the noteworthy events and milestones to watch out for while viewing the animation.
1880s: Breaking the 50-Year Barrier
In the late 19th century, Nordic countries such as Sweden and Norway already found themselves past the 50-year life expectancy mark. This was a significant milestone considering the global life expectancy was a full 20 years shorter at the time. It wasn’t until the year 1960 that the global life expectancy would catch up.
1918: The Spanish Flu and WWI
At times, a confluence of factors can impact health and wealth in countries and regions. In this case, World War I coincided with one of the deadliest pandemics in history, leading to global implications. In the animation, this is abundantly clear as the entire cluster of circles takes a nose dive for a short period of time.
1933, 1960: Communist Famines
At various points in history, human decisions can have catastrophic consequences. This was the case in the Soviet Union (1933) and the People’s Republic of China (1960), where life expectancy plummeted during famines that killed millions of people. These extreme events are easy to spot in the animation due to the large populations of the countries in question.
1960s: Oil Economies Kick into High Gear
During this time, Iran, Iraq, and Saudi Arabia all experience massive booms in wealth, and in the following decade, smaller countries such as the United Arab Emirates and Kuwait rocket to the right edge of the visualization.
In following decades, both Iran and Iraq can be seen experiencing wild fluctuations in both health and wealth as regime changes and conflict begin to destabilize the region.
1990s: AIDS in Africa
In the animation, a number of countries plummet in unison at the end of the 20th century. These are sub-Saharan African countries that were hit hard by the AIDS pandemic. At its peak in the early ’00s, the disease accounted for more than half of deaths in some countries.
1995: Breaking the 65-Year Barrier
Global life expectancy reaches retirement age. At this point in time, there is a clear divide in both health and wealth between African and South Asian countries and the rest of the world. Thankfully, that gap is would continue to narrow in coming years.
1990-2000s: China’s Economic Rise
With a population well over a billion people, it’s impossible to ignore China in any global overview. Starting from the early ’90s, China begins its march from the left to right side of the chart, highlighting the unprecedented economic growth it experienced during that time.
What the Future Holds
If current trends continue, global life expectancy is expected to surpass the 80-year mark by 2100. And, sub-Saharan Africa, which has the lowest life expectancy today, is expected to mostly close the gap, reaching 75 years of age.
Wealth is also expected to increase nearly across the board, with the biggest gains coming from places like Vietnam, Nigeria, and the Philippines. Some experts are projecting the world economy as a whole to double in size by 2050.
There are always bumps along the way, but it appears that the journey to the upper-right quadrant is still very much underway.
How Do Americans Spend Their Money, By Generation?
This interactive graphic shows a breakdown of how average Americans spend their money, and how expenses vary across generations.
How Americans Spend Their Money, By Generation
In 2021, the average American spent just over $60,000 a year. But where does all their money go? Unsurprisingly, spending habits vary wildly depending on age.
This graphic by Preethi Lodha uses data from the U.S. Bureau of Labor Statistics to show how average Americans spend their money, and how annual expenses vary across generations.
A Generational Breakdown of Overall Spending
Overall in 2021, Gen X (anyone born from 1965 to 1980) spent the most money of any U.S. generation, with an average annual expenditure of $83,357.
|Generation||Birth Year Range||Average Annual Expenditure (2021)|
|Silent||1945 or earlier||$44,683|
|Boomers||1946 to 1964||$62,203|
|Generation X||1965 to 1980||$83,357|
|Millennials||1981 to 1996||$69,061|
|Generation Z||1997 or later||$41,636|
Gen X has been nicknamed the “sandwich generation” because many members of this age group are financially supporting both their aging parents as well as children of their own.
The second biggest spenders are Millennials with an average annual expenditure of $69,061. Just like Gen X, this generation’s top three spending categories are housing, healthcare, and personal insurance.
On the opposite end of the spectrum, members of Generation Z are the lowest spenders with an average of $41,636. per year. Their spending habits are expected to ramp up, especially considering that in 2022 the oldest Gen Zers are just 25 and still early in their careers.
Similarities Across Generations
While spending habits vary depending on the age group, there are some categories that remain fairly consistent across the board.
One of the most consistent spending categories is housing—it’s by the far the biggest expense for all age groups, accounting for more than 30% of total annual spending for every generation.
|Generation||Average Spend on Housing (2021)||% of Total Spend|
|Silent (1945 or earlier)||$16,656||37.3%|
|Boomers (1946 to 1964)||$21,273||34.2%|
|Generation X (1965 to 1980)||$26,385||31.7%|
|Millennials (1981 to 1996)||$24,052||34.8%|
|Generation Z (1997 or later)||$15,449||37.1%|
Another spending category that’s surprisingly consistent across every generation is entertainment. All generations spent more than 4% of their total expenditures on entertainment, but none dedicated more than 5.6%.
|Generation||Average Spend on Entertainment (2021)||% of Total Spend|
|Silent (1945 or earlier)||$2,027||4.5%|
|Boomers (1946 to 1964)||$3,476||5.6%|
|Generation X (1965 to 1980)||$4,694||5.6%|
|Millennials (1981 to 1996)||$3,457||5.0%|
|Generation Z (1997 or later)||$1,693||4.1%|
Gen Zers spent the least on entertainment, which could boil down to the types of entertainment this generation typically enjoys. For instance, a study found that 51% of respondents aged 13-19 watch videos on Instagram on a weekly basis, while only 15% watch cable TV.
Differences Across Generations
One category that varies the most between generations and relative needs is spending on healthcare.
As the table below shows, the Silent Generation spent an average of $7,053 on healthcare, or 15.8% of their total average spend. Comparatively, Gen Z only spent $1,354 on average, or 3.3% of their total average spend.
|Generation||Average Spend on Healthcare (2021)||% of Total Spend|
|Silent (1945 or earlier)||$7,053||15.8%|
|Boomers (1946 to 1964)||$6,594||10.6%|
|Generation X (1965 to 1980)||$5,550||6.7%|
|Millennials (1981 to 1996)||$4,026||5.8%|
|Generation Z (1997 or later)||$1,354||3.3%|
However, while the younger generations typically spend less on healthcare, they’re also less likely to be insured—so those who do get sick could be left with a hefty bill.
The Biggest Tech Talent Hubs in the U.S. and Canada
6.5 million skilled tech workers currently work in the U.S. and Canada. Here we look at the largest tech hubs across the two countries
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:
|🇺🇸 Market||Total Tech Talent||% Talent Growth (2016-2021)|
|SF Bay Area||378,870||13%|
|New York Metro||344,520||3%|
|Salt Lake City||55,930||29%|
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:
|🇨🇦 Market||Total Tech Talent||% Talent Growth (2016-2021)|
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?
