In some countries, teaching is a six-figure career. In others, salaries remain far lower even after decades of experience.

This chart compares statutory salaries for upper secondary teachers across OECD countries, using PPP-adjusted 2022 dollars. Data comes from the OECD’s Education at a Glance 2025 report.

To put this in perspective, the highest-paid teachers earn more than double the OECD average top salary of about $76,000, highlighting how wide the global pay gap can be.

Where Teacher Pay Reaches Six Figures

Luxembourg stands far ahead, with starting salaries near $100,000 and top pay reaching over $170,000.

Germany and Switzerland also offer six-figure peak salaries, but still trail Luxembourg by a wide margin. This gap shows how much outliers can skew global comparisons.

Mid-Tier Countries Show Strong Growth Potential

While starting pay is moderate in countries like Canada and the Netherlands, long-term earnings can rise significantly. In Canada, salaries increase from roughly $50K to over $87K, one of the largest jumps in the dataset.

The Netherlands also shows one of the steepest pay progressions in the dataset.

Where Teacher Pay Falls Furthest Behind

At the lower end of the scale, starting salaries in countries like Slovakia, Greece, and Brazil can fall below $30K. Even at peak levels, earnings often remain below the OECD average, highlighting major disparities in how education systems compensate teachers.

In some countries, salaries increase very little over time, limiting long-term earnings. This can contribute to teacher shortages, lower retention, and differences in education quality.

Mapped: America’s Best States to Live In

See visuals like this from many other data creators on our Voronoi app. Download it for free on iOS or Android and discover data-driven charts from a variety of trusted sources.

What makes a state a great place to live in 2025?

Using data from WalletHub, which evaluates 51 metrics across affordability, economic opportunity, safety, and health, this map ranks all 50 U.S. states by quality of life.

The results point to a shift in where Americans can achieve the highest standard of living. While coastal states still lead in income and infrastructure, many Midwest and Mountain states are rising by combining affordability, safety, and economic stability.

Ranked: Where Quality of Life Is Highest in America

Massachusetts tops the ranking thanks to a combination of high incomes, leading healthcare access, and a dense network of top universities, but coastal states no longer dominate the list.

States like Idaho (#2) and New Hampshire (#7) show that quality of life is increasingly driven by safety and economic stability, not just taxes or climate.

Below is the full breakdown of all 50 states, ranked by their total score. Figures are rounded.

One of the clearest trends in the 2025 rankings is the rise of the Midwest as a quality-of-life leader.

With Wisconsin (#4) and Minnesota (#5) in the top five, the region stands out for balancing strong economic, health, and educational outcomes with relatively better affordability.

States Ranking Near the Bottom

The lowest-ranked states cluster into a clear pattern at the bottom of the map.

New Mexico (#50) and Louisiana (#49) remain the only states to score around 40 points, hampered by systemic gaps in healthcare infrastructure and safety.

Moreover, the bottom quartile of the list contains many of the nation’s most “affordable” states. This creates a “livability paradox”: states with the lowest costs often rank poorly overall, as weaker healthcare, safety, and economic mobility offset their affordability advantages.

Ranked: The Busiest U.S. Airports by Flights

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Most airport rankings focus on passenger traffic, but that only tells part of the story. A different metric, aircraft movements, shows how often planes are actually taking off and landing.

Using Federal Aviation Administration data, this visualization by Julie Peasley ranks the busiest U.S. airports by total flights in 2025.

At the top, Chicago O’Hare operates at an almost continuous pace, with a takeoff or landing every 37 seconds.

U.S. Airports With the Most Flights

Here’s a look at America’s top airports by flights:

Chicago O’Hare leads by a wide margin, followed by Atlanta and Dallas/Fort Worth. Notably, the top four airports all exceed 700,000 annual operations, underscoring their immense throughput and operational complexity.

To put this in perspective, here’s how quickly flights move at the top airports:

• O’Hare (ORD): every 37 seconds
• Atlanta (ATL): every 39 seconds
• Dallas/Fort Worth (DFW): every 42 seconds
• Denver (DEN): every 45 seconds

Even small differences translate into tens of thousands of additional flights per year.

Why the Busiest Airport Isn’t Always the Most Crowded

Passenger rankings favor bigger planes. Flight rankings favor more planes. That’s why airports like Chicago O’Hare and Denver rise to the top. They move aircraft more frequently, not just more people.

For context, some of the world’s busiest passenger airports do not appear at the top of this list. That’s because larger aircraft can carry more people per flight, reducing total movements even at high-traffic hubs.

O’Hare’s lead comes down to frequency. Over a full day, that 37-second pace adds up to more than 2,300 flights, far ahead of any other U.S. airport.

Meanwhile, airports like Phoenix Sky Harbor and Charlotte Douglas also rank highly because of their roles as connecting hubs, handling constant waves of arrivals and departures throughout the day.

The Role of Connectivity and Hub Strategy

Airports with strong airline hub operations naturally generate more aircraft movements. Carriers schedule tightly coordinated banks of flights to maximize connections, leading to frequent takeoffs and landings.

According to broader aviation analysis, highly connected airports tend to prioritize network efficiency over sheer passenger volume. This helps explain why hubs like Denver and Dallas/Fort Worth rank so highly, since they act as central nodes in national air travel.

Just How Busy Is “Busy”?

To put these numbers in perspective, even the 10th-ranked airport, New York’s JFK, handles a flight roughly every 67 seconds. At the top end, O’Hare’s near-continuous operations require precise coordination between air traffic control, ground crews, and airlines.

This near-constant flow of aircraft highlights how modern air travel depends on precision and coordination at scale. As flight demand grows, the busiest airports aren’t just moving more people. They’re managing an increasingly nonstop stream of planes.

Ranked: The Best-Selling Video Games in History

See visuals like this from many other data creators on our Voronoi app. Download it for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Video games have produced some of the best-selling entertainment products ever—but the top spot isn’t as clear-cut as it seems.

This ranking uses updated sales data from HP (2026) to compare the top-selling video games of all time, led by Tetris at more than 520 million units sold. However, its position is debated because the game has been released across dozens of platforms since 1984.

If each version is counted separately, Minecraft would take the crown, highlighting how the industry’s biggest hits span generations, platforms, and business models.

Is Tetris Really the Best-Selling Game Ever?

Tetris is widely considered the best-selling video game of all time, but that title depends on how its many versions are counted.

Since 1984, the game has been rereleased across dozens of platforms, contributing to its 520 million total. Some analysts count each version separately. Under that approach, Minecraft would rank as the best-selling single-release game in history.

Despite gaming’s decades-long history, most of the top-selling titles were released after 2010. Franchises like Minecraft, Grand Theft Auto V, and Terraria reflect the shift toward digital distribution, live-service updates, and global player communities.

The Rise of the Creeper

In 2009, Swedish game developer Mojang Studios launched early access for Minecraft, a sandbox game that allows players to create, fight, and mine while engaging with a massive online community.

Nearly two decades later, Minecraft has become the defining game of the modern era, with 350 million copies sold worldwide. It was acquired by Microsoft for $2.5 billion in 2014.

Today, the game’s large fan community has led to the development of the annual Minecon convention, as well as a 2025 film adaptation, A Minecraft Movie, which grossed over $960 million at the box office.

GTA V and the Rockstar Reign

In November 2026, Grand Theft Auto VI is expected to be released. Much of the anticipation stems from its predecessor, Grand Theft Auto V, which generated over $1 billion in sales within three days of its 2013 launch, making it the fastest-selling entertainment product in history at the time.

Since then, Grand Theft Auto V has sold over 225 million copies worldwide, surpassing even bundled titles like Nintendo’s Wii Sports (83 million).

Few games released since Grand Theft Auto V have matched its commercial success. Red Dead Redemption 2, also developed by Rockstar Games, has reached 82 million sales, ahead of titles like Mario Kart 8 Deluxe (79 million), The Elder Scrolls V: Skyrim (60 million), and Super Mario Bros. (58 million).

Your state might play a bigger role in your happiness than you think.

This map ranks all 50 states using a composite “happiness score,” revealing a wide gap between top-performing states like Hawaii and lower-ranked ones like West Virginia. The difference between first and last place exceeds 30 points, highlighting stark disparities in well-being across the country.

The data comes from WalletHub, which evaluated states across 30 metrics tied to emotional and physical health, income growth, work conditions, and community factors.

Why Hawaii and the Northeast Dominate the Rankings

Hawaii’s top ranking reflects strong performance across emotional well-being and community-related metrics.

The Northeast stands out as a clear hotspot for happiness, with multiple states clustering near the top of the rankings. In contrast, much of the South appears near the bottom, reinforcing a clear regional divide in overall well-being.

The data table below shows the happiness score and ranking of all 50 U.S. states:

Rank	State	Happiness Score
1	Hawaii	65.5
2	Maryland	64.1
3	Nebraska	63.6
4	New Jersey	63.4
5	Connecticut	62.5

47	Alabama	40.7
48	Arkansas	37.0
49	Louisiana	34.3
50	West Virginia	32.0
--	Average	51.2

One surprise in the rankings is Nebraska, which places third overall ahead of larger and wealthier states. Its strong performance reflects consistent results across multiple categories rather than dominance in any single metric.

Meanwhile, among the four most populous states, results vary widely, highlighting how size alone does not determine quality of life. California ranks 7th overall, while Texas falls to 37th, creating one of the largest gaps among peer states in the ranking.

Southern States Have the Lowest Happiness

The lowest-ranked states cluster heavily in the South, with West Virginia, Louisiana, and Arkansas all scoring well below the national average. These states tend to rank poorly in both health outcomes and work environment metrics, two of the most heavily weighted components in the index.

West Virginia’s last-place finish is driven by bottom rankings in both emotional and physical well-being and work environment. Louisiana also ranks 49th in those two categories, though a mid-pack community and environment result keeps it narrowly ahead of West Virginia overall.

How WalletHub Built the Happiness Ranking

WalletHub says the study draws on 30 indicators, ranging from depression rates and the share of adults feeling productive to income growth and unemployment. According to the source methodology, the underlying data used to build the ranking was collected as of June 23, 2025, from a mix of federal agencies, Gallup, TransUnion, Sharecare, AmeriCorps, and other organizations.

Rather than capturing momentary mood, the ranking reflects broader living conditions. By combining health, economic, and community indicators, it offers a more comprehensive view of what drives happiness across states.

Ranked: The World’s Largest Exporters in 2025

See visuals like this from many other data creators on our Voronoi app. Download it for free on iOS or Android and discover data-driven charts from a variety of trusted sources.

Global trade is dominated by a handful of export powerhouses—but the scale gap between them is striking.

China exported nearly $3.8 trillion in goods in 2025, maintaining a wide lead over the United States and every other economy. Meanwhile, Europe collectively accounts for a massive share of global exports, and smaller trade hubs like the Netherlands and UAE continue to punch far above their weight.

This graphic ranks the world’s 30 largest exporters using the latest data from the World Trade Organization.

China: The World’s Top Exporter

China’s $3.8 trillion in exports is nearly double that of the United States, underscoring the scale of its dominance in global manufacturing and trade.

Beginning with the country’s gradual liberalization in the late 1970s and 1980s, China pursued an export-driven growth model that sought to position the country as “the world’s factory floor.” Today, no country ships more merchandise abroad.

This data table lists the world’s top exporters and their 2025 goods export value.

Rank	Country	Value (Billion USD)
1	China	3,772
2	United States	2,185
3	Germany	1,764
4	Netherlands	989
5	Hong Kong	754
6	Japan	738
7	Italy	726
8	South Korea	709
9	United Arab Emirates	707
10	France	683
11	Mexico	665
12	Taiwan	641
13	Belgium	568
14	Singapore	567
15	United Kingdom	556
16	Canada	555
17	Switzerland	554
18	Vietnam	473
19	India	445
20	Spain	445
21	Russia	419
22	Poland	414
23	Malaysia	376
24	Brazil	348
25	Thailand	340
26	Australia	338
27	Saudi Arabia	311
28	Ireland	293
29	Czech Republic	284
30	Indonesia	283

China’s expansive exports have been boosted by its various free-trade agreements, including with Australia, Pakistan, South Korea, and the ASEAN bloc of Southeast Asian markets.

The effect is undeniable: China is today the largest trade partner of over half the world’s countries, playing an increasingly central commercial role for developed and emerging markets across all continents.

The U.S. Export Profile

The United States may be best known today as the world’s largest import market, but it’s also responsible for over $2.2 trillion worth of diversified exports including cars, oil, soy, and medical products.

The top U.S. trade partners include its North American neighbors, Canada and Mexico, as well as China, Germany, and Japan.

Integrated North American supply chains mean that many U.S. exports actually obtain their inputs from imports across the border. Car parts, for example, may cross a U.S. border with either Canada or Mexico some six to eight times during the vehicle assembly process.

The Export Prominence of the Persian Gulf

Gulf states like Saudi Arabia ($311 billion) and the United Arab Emirates ($707 billion) also punch quite above their weight as exporters, aided by their sprawling hydrocarbon reserves.

Oil products make up nearly 75% of Saudi exports and over half of Emirati exports, in contrast to the less than 20% share seen in the U.S., the world’s largest oil producer.

The Gulf countries’ high dependence on their petroleum production thus makes them vulnerable to geopolitical tensions and supply chain disruptions in the Middle East, with the ongoing conflict involving Iran emerging as a clear example.
