How Global Health and Wealth Has Changed Over Two Centuries



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.

3 Insights From the FED’s Latest Economic Snapshot

3 Insights From the Latest U.S. Economic Data

Each month, the Federal Reserve Bank of New York publishes monthly economic snapshots.

To make this report accessible to a wider audience, we’ve identified the three most important takeaways from the report and compiled them into one infographic.

1. Growth figures in Q2 will make or break a recession

Generally speaking, a recession begins when an economy exhibits two consecutive quarters of negative GDP growth. Because U.S. GDP shrank by -1.5% in Q1 2022 (January to March), a lot rests on the Q2 figure (April to June) which should be released on July 28th.

Referencing strong business activity and continued growth in consumer spending, economists predict that U.S. GDP will grow by +2.1% in Q2. This would mark a decisive reversal from Q1, and put an end to recessionary fears for the time being.

Unfortunately, inflation is the top financial concern for Americans, and this is dampening consumer confidence. Shown below, the consumer confidence index reflects the public’s short-term outlook for income, business, and labor conditions.

consumer price index 2005 to 2022

Falling consumer confidence suggests that more people will delay big purchases such as cars, major appliances, and vacations.

2. The COVID-era housing boom could be over

Housing markets have been riding high since the beginning of the COVID-19 pandemic, but this run is likely coming to an end. Here’s a summary of what’s happened since 2020:

  • Lockdowns in early 2020 created lots of pent-up demand for homes
  • Greater household savings and record-low mortgage rates pushed demand even further
  • Supply chain disruptions greatly increased the cost of materials like lumber
  • Construction of new homes couldn’t keep up, and housing supply fell to historic lows

Today, home prices are at record highs and the cost of borrowing is rapidly rising. For evidence, look no further than the 30-year fixed mortgage rate, which has doubled to more than 6% since the beginning of 2022.

Given these developments, the drop in the number of home sales could be a sign that many Americans are being priced out of the market.

3. Don’t expect groceries to become any cheaper

Inflation has been a hot topic this year, especially with gas prices reaching $5 a gallon. But there’s one category of goods that’s perhaps even more alarming: food.

The following table includes food inflation over the past three years, as the percent change over the past 12 months.

DateCPI Food Component (%)

From this data, we can see that food inflation really picked up speed in April 2020, jumping to +3.5% from +1.9% in the previous month. This was due to supply chain disruptions and a sudden rebound in global demand.

Fast forward to today, and food inflation is running rampant at 10.1%. A contributing factor is the impending fertilizer shortage, which stems from the Ukraine war. As it turns out, Russia is not only a massive exporter of oil, but wheat and fertilizer as well.

Mapped: A Decade of Population Growth and Decline in U.S. Counties

This map shows which counties in the U.S. have seen the most growth, and which places have seen their populations dwindle in the last 10 years.



A Decade of Population Growth and Decline in U.S. Counties

There are a number of factors that determine how much a region’s population changes.

If an area sees a high number of migrants, along with a strong birth rate and low death rate, then its population is bound to increase over time. On the flip side, if more people are leaving the area than coming in, and the region’s birth rate is low, then its population will likely decline.

Which areas in the United States are seeing the most growth, and which places are seeing their populations dwindle?

This map, using data from the U.S. Census Bureau, shows a decade of population movement across U.S. counties, painting a detailed picture of U.S. population growth between 2010 and 2020.

Counties With The Biggest Population Growth from 2010-2020

To calculate population estimates for each county, the U.S. Census Bureau does the following calculations:

A county’s base population → plus births → minus deaths → plus migration = new population estimate

From 2010 to 2020, Maricopa County in Arizona saw the highest increase in its population estimate. Over a decade, the county gained 753,898 residents. Below are the counties that saw the biggest increases in population:

RankCountyPoint of ReferenceStatePop. Growth (2010–2020)
#1Maricopa CountyPhoenix, ScottsdaleArizona+753,898
#2Harris CountyHoustonTexas+630,711
#3Clark CountyLas VegasNevada+363,323
#4King CountySeattleWashington+335,884
#5Tarrant CountyFort Worth, ArlingtonTexas+305,180
#6Bexar CountySan AntonioTexas+303,982
#7Riverside CountyRiverside, Palm SpringsCalifornia+287,626
#8Collin CountyPlanoTexas+284,967
#9Travis CountyAustinTexas+270,111
#10Hillsborough CountyTampaFlorida+264,446

Phoenix and surrounding areas grew faster than any other major city in the country. The region’s sunny climate and amenities are popular with retirees, but another draw is housing affordability. Families from more expensive markets—California in particular—are moving to the city in droves. This is a trend that spilled over into the pandemic era as more people moved into remote and hybrid work situations.

Texas counties saw a lot of growth as well, with five of the top 10 gainers located in the state of Texas. A big draw for Texas is its relatively affordable housing market. In 2021, average home prices in the state stood at $172,500$53,310 below the national average.

Counties With The Biggest Population Drops from 2010-2020

On the opposite end of the spectrum, here’s a look at the top 10 counties that saw the biggest declines in their populations over the decade:

RankCountyPoint of ReferenceStatePop. Growth (2010–2020)
#1Cook CountyChicagoIllinois-90,693
#2Wayne CountyDetroitMichigan-74,224
#3Cuyahoga CountyClevelandOhio-50,220
#4Genesee CountyFlintMichigan-20,165
#5Suffolk CountyLong IslandNew York-20,064
#6Caddo ParishShreveportLouisiana-18,173
#7Westmoreland CountyMurrysvillePennsylvania-17,942
#8Hinds CountyJacksonMississippi-17,751
#9Kanawha CountyCharlestonWest Virginia-16,672
#10Cambria CountyJohnstownPennsylvania-14,786

The largest drops happened in counties along the Great Lakes, including Cook County (which includes the city of Chicago) and Wayne County (which includes the city of Detroit).

For many of these counties, particularly those in America’s “Rust Belt”, population drops over this period were a continuation of decades-long trends. Wayne County is an extreme example of this trend. From 1970 to 2020, the area lost one-third of its population.

U.S. Population Growth in Percentage Terms (2010-2020)

While the map above is great at showing where the greatest number of Americans migrated, it downplays big changes in counties with smaller populations.

For example, McKenzie County in North Dakota, with a 2020 population of just 15,242, was the fastest-growing U.S. county over the past decade. The county’s 138% increase was driven primarily by the Bakken oil boom in the area. High-growth counties in Texas also grew as new sources of energy were extracted in rural areas.

The nation’s counties are evenly divided between population increase and decline, and clear patterns emerge.

Pandemic Population Changes

More recent population changes reflect longer-term trends. During the COVID-19 pandemic, many of the counties that saw the strongest population increases were located in high-growth states like Florida and Texas.

Below are the 20 counties that grew the most from 2020 to 2021.

#18Ada CountyBoiseIdaho+13,947
#19Osceola CountyKissimmeeFlorida+12,427
#20St. Lucie CountyFort PierceFlorida+12,304

Many of these counties are located next to large cities, reflecting a shift to the suburbs and larger living spaces. However, as COVID-19 restrictions ease, and the pandemic housing boom tapers off due to rising interest rates, it remains to be seen whether the suburban shift will continue, or if people begin to migrate back to city centers.
