The world is in the midst of a notable period of demographic transition.
Back in the 1960s, global population growth peaked at a 2.1% annual rate, but since then it has been on a historic downtrend.
In fact, according to the most commonly cited United Nations projection, which is based on a medium fertility rate scenario, it’s expected that annual population growth could drop all the way to 0.1% by the end of the 21st century.
Visualizing a Demographic Transition
Today’s powerful charts come from Our World in Data by economist Max Roser, and they show how global demographics will shift over the next 80 years.
Below you can see one major catalyst of this change, which is the peaking (and then falling) population growth rate:
Why has population growth been dropping since the 1960s?
A variety of explanations factor into this, including:
- Falling fertility rates:
Birth rates tend to fall as nations get richer. First, this happened in the developed world, but as the century progresses this phenomenon will impact more and more developing nations.
- Government policy:
China’s “One Child Policy” in particular had an effect on global population growth, and the aftermath of the policy is still contributing to a shrinking Chinese population over the long term.
- Rural flight
Urban dwellers tend to have fewer babies – and by 2050, there will be an additional 2.5 billion people living in cities globally.
Fewer births combined with improving healthcare – especially in developing nations – will dramatically alter the composition of the world population pyramid, creating both economic opportunities and challenges in the process.
The Changing World Population Pyramid
The following graphic charts how these changes affect the makeup of the world’s population.
Over time, the shape of the world population pyramid is expected to shift from Stage 1 (high birth rates, high death rates) to something closer to Stage 4 (low birth rates, low death rates).
As the population distribution skews older, here is how population size and global median age will change:
|Year||Global Population Size||Median Age|
|1950||2.6 billion||23.6 years|
|2018||7.6 billion||30.0 years|
|2050||9.7 billion||36.1 years|
|2075||10.7 billion||39.0 years|
|2100||11.2 billion||41.6 years|
Dates past 2018 are projections by the United Nations
Global median age is projected to surpass 40 years by the end of the century, and it will be considerably higher in many Western nations, especially in Japan and Europe.
With the future demographic composition looking very different than today, it will be fascinating to see how the economy responds to these potential tailwinds. Further, it will be even more interesting to see what role automation will play as the old-age dependency ratio hits historic highs.
Ranked: The 50 Most Popular Fast Food Chains in America
What’s America been craving? Here’s a look at the top 50 most popular fast food chains, ranked by U.S. sales in 2019.
The 50 Most Popular Fast Food Chains in America
Millions of Americans eat at fast food restaurants every day—and they now have more options at their disposal than ever before.
From burgers to pad thai, there’s a quick service restaurant that’ll satisfy almost any appetite. With all this choice, which fast food chains are the most popular among consumers?
Using data from QSR Magazine, today’s infographic ranks the top 50 largest fast food chains in the U.S. by sales in 2019, providing insight into the types of foods Americans have been craving.
Fast Food Chains Ranked, by Revenue
In 2019, the 50 largest fast food chains in the U.S. generated over $200 billion in revenue. How do these quick service giants stack up against each other?
|Rank||Company||Category||U.S. Sales, Billions (2019)|
|19||Popeyes Louisiana Kitchen||Chicken||$3.75|
|20||Jack in the Box||Burger||$3.51|
|34||Steak 'n Shake||Burger||$0.93|
|35||El Pollo Loco||Chicken||$0.89|
|49||Tropical Smoothie Café||Snack||$0.58|
Unsurprisingly, McDonald’s comes in at number one with over $40 billion in sales. Despite a scandal involving its former CEO, McDonald’s still managed to significantly outsell its peers—the company made almost double that of the second-largest fast food chain, Starbucks.
But don’t worry, Starbucks did just fine for itself. With $21 billion in sales, the Seattle-based coffee chain saw a 5% increase compared to its numbers in 2018.
Top Selling Fast Food Categories
Based on the ranking, it’s clear that Americans still love their McDonald’s. But are burgers, in general, the most popular fast food item?
In short—yes. Burgers are king. Here’s a look at how burgers, pizza, chicken, and other food categories measure up:
Burger joints remain the most popular fast food option among consumers—14 of the 50 chains on the list are classified as burger restaurants, with $80 billion in collective sales.
Snacks come in at second place, with a total of $36 billion in revenue. Boasting a broad variety of foods from iced coffee to donuts and ice cream, six of the restaurants on the list are included in this category. Starbucks is the most popular, followed by Dunkin’ and Dairy Queen respectively.
While the chicken and sandwich categories both have nine restaurants included in the ranking, chicken restaurants outsold sandwiches by almost $1 billion. This is largely due to Chick-fil-A, which makes up more than a third of all chicken restaurant sales included in the ranking.
It’s important to note that these numbers reflect the fast food industry before the devastating impacts of COVID-19. The global pandemic has forced many fast food restaurants to adapt, and it’s also triggered a number of restaurant shutdowns.
For instance, McDonald’s is set to permanently close 200 of its 14,000 U.S. locations, and Dunkin’ will be closing 450 restaurants by the end of 2020. Starbucks has also announced it’s planning to permanently shut down up to 400 locations by mid-2021.
With online sales more important than ever, the chains with a strong digital presence may be in a better position to weather the storm. Chains with physical distancing options, such as drive-throughs, could also recover quicker.
Visualizing the Range of EVs on Major Highway Routes
We visualize how far popular EV models will take you on real-world routes between major cities, and which are the most cost effective.
The Range of EVs on Major Highway Routes
Between growing concerns around climate change, new commuting behaviors due to COVID-19, and imminent policy changes, the global transition to electric vehicles (EVs) is well under way.
By the year 2040, sales of electric vehicles are projected to account for 58% of new car sales, up from just 2.7% currently.
But switching from a gasoline car to an electric one is not seamless. With charging and range capacities to consider, and the supporting infrastructure still being slowly rolled out in many parts of the world, understanding the realities of EV transportation is vital.
Above, we highlight 2020 all-electric vehicle range on well-recognized routes, from California’s I-5 in the U.S. to the A2 autobahn in Germany. The data on estimated ranges and costs are drawn from the U.S. EPA as well as directly from manufacturer websites.
The EV Breakdown: Tesla is King of Range
For many consumers, the most important aspect of an electric vehicle is how far they can travel on a single charge.
Whether it’s for long commutes or out-of-city trips, vehicles must meet a minimum threshold to be considered practical for many households. As the table below shows, Tesla’s well-known EVs are far-and-away the best option for long range drivers.
|Vehicle||Range (miles)||Range (km)||MSRP||Cost per mile|
|Tesla Model S Long Range Plus||402||647||$74,990||$186.54|
|Tesla Model X Long Range Plus||351||565||$79,990||$227.89|
|Tesla Model S Performance||348||560||$94,990||$272.96|
|Tesla Model 3 Long Range||322||518||$46,990||$145.93|
|Tesla Model Y Long Range||316||509||$49,990||$158.20|
|Tesla Model X Performance||305||491||$99,990||$327.84|
|Tesla Model 3 LR Performance||299||481||$54,990||$183.91|
|Tesla Model Y Performance||291||468||$59,990||$206.15|
|Chevrolet Bolt EV||259||417||$36,620||$141.39|
|Hyundai Kona Electric||258||415||$37,190||$144.15|
|Tesla Model 3 Standard Range Plus||250||402||$37,990||$151.96|
|Kia Niro EV||239||385||$39,090||$163.56|
|Nissan LEAF e+ S||226||364||$38,200||$169.03|
|Audi e-tron Sportback||218||351||$69,100||$316.97|
|Nissan LEAF e+ SV/SL||215||346||$39,750||$184.88|
|Porsche Taycan 4S Perf Battery Plus||203||327||$112,990||$556.60|
|Porsche Taycan Turbo||201||323||$153,510||$763.73|
|Porsche Taycan Turbo S||192||309||$187,610||$977.14|
|Hyundai IONIQ Electric||170||274||$33,045||$194.38|
|MINI Cooper SE||110||177||$29,900||$271.82|
In an industry where innovation and efficiency are vital, Tesla’s first-mover advantage is evident. From the more affordable Model 3 to the more luxurious Model S, the top eight EVs with the longest ranges are all Tesla vehicles.
At 402 miles (647 km), the range of the number one vehicle (the Tesla Model S Long Range Plus) got 127 miles more per charge than the top non-Tesla vehicle, the Polestar 2—an EV made by Volvo’s standalone performance brand.
Closer Competition in Cost
Though Tesla leads on overall range and battery capacity, accounting for the price of each vehicle shows that cost-efficiency is far more competitive among brands.
By dividing the retail price by the maximum range of each vehicle, we can paint a clearer picture of efficiency. Leading the pack is the Chevrolet Bolt, which had a cost of $141.39/mile of range in 2020 while still placing in the top 10 for range with 259 miles (417 km).
Just behind in second place was the Hyundai Kona electric at $144.15/mile of range, followed by the Tesla Model 3—the most efficient of the automaker’s current lineup. Rounding out the top 10 are the Nissan LEAF and Tesla Model S, but the difference from number one to number ten was minimal, at just over $45/mile.
|Top 10 All-Electric Vehicles by Cost Efficiency|
|Vehicle||Cost per mile|
|Chevrolet Bolt EV||$141.39|
|Hyundai Kona Electric||$144.15|
|Tesla Model 3 Long Range||$145.93|
|Tesla Model 3 Standard Range Plus||$151.96|
|Tesla Model Y Long Range||$158.20|
|Kia Niro EV||$163.56|
|Nissan LEAF e+ S||$169.03|
|Tesla Model 3 LR Performance||$183.91|
|Nissan LEAF e+ SV/SL||$184.88|
|Tesla Model S Long Range Plus||$186.54|
Higher Ranges and Lower Costs on the Horizon
The most important thing to consider, however, is that the EV industry is entering a critical stage.
On one hand, the push for electrification and innovation in EVs has driven battery capacity higher and costs significantly lower. As batteries account for the bulk of weight, cost, and performance in EVs, those dividends will pay out in longer ranges and greater efficiencies with newer models.
Equally important is the strengthening global push for electric vehicle adoption. In countries like Norway, EVs are already among the best selling cars on the market, while adoption rates in China and the U.S. are steadily climbing. This is also being impacted by policy decisions, such as California’s recent announcement that it would be banning the sale of gasoline cars by 2035.
Meanwhile, the only thing outpacing the growing network of Tesla superchargers is the company’s rising stock price. Not content to sit on the sidelines, competing automakers are rapidly trying to catch up. Nissan’s LEAF is just behind the Tesla Model 3 as the world’s second-best-selling EV, and Audi recently rolled out a supercharger network that can charge its cars from 0% to 80% at a faster rate than Tesla.
As the tidal wave of electric vehicle demand and adoption continues to pick up steam, consumers can expect increasing innovation to drive up ranges, decrease costs, and open up options.
