Key Takeaways

  • Qatar’s population grew by over 400%, the fastest increase globally since 2000.
  • Ukraine’s population fell by roughly one-third, the steepest decline.
  • A clear divide is emerging: rapid growth in the Gulf and Africa vs. shrinking populations in Eastern Europe.

Over the past 25 years, some countries have more than tripled their populations, while others have seen sharp declines that are reshaping their economies and societies.

This graphic uses IMF data to rank the 24 countries with the fastest population growth and decline since 2000, measured by total percentage change.

Gulf States Lead the World in Population Growth

The Persian Gulf dominates the growth rankings—but not because of high birth rates.

Qatar leads the world with a staggering 423% population increase, growing from roughly 594,000 to 3.1 million. The UAE follows at 250%, while Bahrain (+154%), Kuwait (+139%), and Oman (+129%) also rank among the top 10.

The data table below shows the top 24 countries by population growth from 2000 to 2025:

Rank Country Population Growth 2000–2025
1 🇶🇦 Qatar 423.4%
2 🇦🇪 United Arab Emirates 249.7%
3 🇬🇶 Equatorial Guinea 166.6%
4 🇳🇪 Niger 157.0%
5 🇧🇭 Bahrain 153.9%
6 🇵🇬 Papua New Guinea 149.6%
7 🇦🇴 Angola 139.7%
8 🇰🇼 Kuwait 139.1%
9 🇴🇲 Oman 129.1%
10 🇹🇩 Chad 126.9%
11 🇯🇴 Jordan 126.3%
12 🇧🇮 Burundi 123.6%
13 🇨🇩 Democratic Republic of the Congo 121.8%
14 🇺🇬 Uganda 120.1%
15 🇿🇲 Zambia 119.5%
16 🇲🇱 Mali 118.4%
17 🇾🇪 Yemen 112.9%
18 🇬🇲 Gambia 112.8%
19 🇲🇬 Madagascar 108.7%
20 🇨🇬 Republic of Congo 107.0%
21 🇧🇯 Benin 106.6%
22 🇹🇿 Tanzania 106.4%
23 🇲🇿 Mozambique 102.3%
24 🇨🇮 Ivory Coast 102.3%

These surges are almost entirely driven by imported labor migration. Massive construction projects, oil and gas expansion, and broader economic diversification efforts drew millions of foreign workers to the region over the past two decades.

Outside the Gulf, the fastest-growing populations are concentrated in sub-Saharan Africa. Equatorial Guinea (+167%), Niger (+157%), and Papua New Guinea (+150%) round out the top five.

Angola (+140%), Chad (+127%), the Democratic Republic of the Congo (+122%), Burundi (+124%), Uganda (+120%), and Zambia (+120%) all more than doubled their populations. High fertility rates and gradually improving healthcare have sustained rapid growth across the region.

Eastern Europe’s Population Collapse

In contrast, much of Eastern Europe is experiencing sustained population decline. Bulgaria (-23%), Latvia (-22%), Moldova (-19%), and Lithuania (-18%) have all lost roughly a fifth or more of their populations since 2000.

Ukraine stands apart with the steepest decline at -33%, losing roughly 16 million people—from 48.7 million in 2000 to an estimated 32.9 million in 2025. Along with long-term economic factors, the war with Russia has accelerated Ukraine’s population decline.

The data table below shows the top 24 countries by population decline from 2000 to 2025:

Rank Country/Territory Population Decline 2000–2025
1 🇺🇦 Ukraine -32.5%
2 🇲🇭 Marshall Islands -29.4%
3 🇧🇬 Bulgaria -23.2%
4 🇱🇻 Latvia -21.6%
5 🇲🇩 Moldova -18.8%
6 🇱🇹 Lithuania -17.5%
7 🇵🇷 Puerto Rico -16.7%
8 🇷🇴 Romania -16.1%
9 🇷🇸 Serbia -13.1%
10 🇦🇱 Albania -12.8%
11 🇭🇷 Croatia -12.0%
12 🇫🇲 Micronesia -11.2%
13 🇬🇪 Georgia -10.3%
14 🇲🇰 North Macedonia -10.0%
15 🇧🇾 Belarus -9.0%
16 🇧🇦 Bosnia and Herzegovina -8.2%
17 🇭🇺 Hungary -6.5%
18 🇵🇼 Palau -5.3%
19 🇵🇱 Poland -4.6%
20 🇬🇷 Greece -3.7%
21 🇦🇲 Armenia -3.3%
22 🇯🇵 Japan -2.8%
23 🇪🇪 Estonia -1.6%
24 🇷🇺 Russia -0.7%

The pattern is consistent: after EU accession opened borders to higher-wage Western European economies, working-age emigration accelerated. This compounded an already-low birth rate across the region, creating a demographic squeeze that has left many of these countries with aging, shrinking populations.

Puerto Rico (-17%), Romania (-16%), and Serbia (-13%) follow a similar trajectory. Even larger countries like Poland (-5%) and Japan (-3%) saw population declines, though at more modest rates relative to their size. Russia rounds out the list, with its population falling by just under 1% since 2000.

Mapped: How the Euro Spread Across Europe Since 1999

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.

Key Takeaways

  • The eurozone has grown from 12 countries in 1999 to 21 in 2026.
  • Bulgaria became the latest member in 2026, adopting the euro.
  • Five EU countries have yet to join, despite being expected to eventually adopt the currency.

Since its launch in 1999, the euro has spread across much of Europe, becoming one of the world’s most widely used currencies.

This map highlights how the eurozone has expanded since its founding in 1999, utilizing official 2026 European Union statistics.

In January 2026, Bulgaria became the 21st eurozone member—marking the first expansion of the currency bloc since Croatia joined in 2023.

Eurozone: Growth Snapshot

  • 1999: 12 founding members
  • 2001–2015: Gradual expansion across Southern and Eastern Europe
  • 2023–2026: Two new members (Croatia and Bulgaria)
  • Today: 21 total countries using the euro

The Eurozone as of 2026

The eurozone was formed in 1999 by 12 founding members in Northern and Western Europe, including France, Germany, Italy, and Spain. Since then, nine more countries have joined, including most recently Croatia in 2023 and Bulgaria in 2026.

Per monetary agreements with the European Union, four European microstates can also use the euro despite not being eurozone members: Andorra, Monaco, San Marino, and Vatican City.

The following data table lists European countries alongside the year they began to use the euro.

Country Euro Adopted in Year
🇦🇹 Austria 1999
🇧🇪 Belgium 1999
🇫🇮 Finland 1999
🇫🇷 France 1999
🇩🇪 Germany 1999
🇮🇪 Ireland 1999
🇮🇹 Italy 1999
🇱🇺 Luxembourg 1999
🇳🇱 Netherlands 1999
🇵🇹 Portugal 1999
🇪🇸 Spain 1999
🇦🇩 Andorra 1999
🇲🇨 Monaco 1999
🇸🇲 San Marino 1999
🇻🇦 Vatican City 1999
🇬🇷 Greece 2001
🇽🇰 Kosovo 2002
🇲🇪 Montenegro 2002
🇸🇮 Slovenia 2007
🇨🇾 Cyprus 2008
🇲🇹 Malta 2008
🇸🇰 Slovakia 2009
🇪🇪 Estonia 2011
🇱🇻 Latvia 2014
🇱🇹 Lithuania 2015
🇭🇷 Croatia 2023
🇧🇬 Bulgaria 2026

The eurozone is the largest currency union in the world, and has its monetary policy set by the European Central Bank, headquartered in Frankfurt, Germany. Currencies on other continents, such as the West African CFA franc, are pegged to the euro as a legacy of their historical relationship to the French franc.

In total, 21 of the European Union’s current 27 member countries have joined, including the bloc’s five largest economies and all of its founding members. The union famously came into crisis in the late 2000s and early 2010s as multiple eurozone members, including Italy, Greece, and Spain, suffered simultaneous financial crises.

The Future of the Eurozone

All EU member countries are expected to adopt the euro upon reaching certain monetary criteria. The only exception to this rule is Denmark, which negotiated a permanent opt-out in the 1990s allowing it to legally avoid euro adoption as long as it wanted. Prior to leaving the EU in 2020, the United Kingdom had also obtained this opt-out.

Five EU countries—Czechia, Hungary, Poland, Romania, and Sweden—still don’t use the euro, despite being expected to adopt it eventually.

However, progress has been uneven. Joining the euro requires meeting strict economic criteria, and participation in the ERM II system remains voluntary—slowing the path to adoption for several countries.

Unilateral Euro Adoption

In addition to the 21 members of the eurozone and the four microstates with monetary agreements, there are two European countries which have unilaterally adopted the euro: Kosovo and Montenegro.

These two countries, which each broke away from Serbia in the 2000s, adopted the euro in 2002 after having previously used the German mark instead of the Yugoslav dinar. At the transition from the mark to the euro, both switched to the new currency, despite no authorization to do so by the European Union and subsequently no ability to mint their own banknotes.

The EU generally frowns upon this practice of non-EU countries adopting the euro unilaterally. In fact, EU officials have even indicated that unilateral euro adoption could jeopardize a country’s eventual accession to the European Union.

Ranked: The Countries Building the Most Nuclear Power

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.

Key Takeaways

  • China is on track to more than double U.S. nuclear capacity, reaching nearly 186 GW.
  • The U.S. leads today but ranks second when planned projects are included.
  • Emerging players like India and Uganda are rapidly scaling nuclear capacity from near zero.

China is set to become the world’s dominant nuclear power producer.

Based on existing and planned projects, its total capacity could reach nearly 186 gigawatts, far surpassing the U.S., which currently leads globally. This shift reflects a broader push to secure reliable, low-carbon energy as electricity demand rises.

This chart ranks countries by current and prospective nuclear capacity, using data from Global Energy Monitor.

How Nuclear Energy Is Set to Scale by Country

The U.S. currently leads nuclear energy production with a capacity of 102,475 megawatts, exceeding France by more than 35,000 MW.

China ranks third today at 60,898 MW, but that is set to change as new plants come online.

Dive into the data, which includes sites of any capacity as of September 2025, below:

Country Operating Nuclear Power (GW) Prospective Nuclear Power (GW) Total Future Nuclear Power (GW)
🇨🇳 China 60.9 124.9 185.8
🇺🇸 United States 102.5 15.4 117.9
🇫🇷 France 65.7 9.9 75.6
🇷🇺 Russia 28.6 32.2 60.7
🇮🇳 India 8.2 31.5 39.7
🇰🇷 South Korea 27.1 5.6 32.7
🇺🇦 Ukraine 13.8 8.4 22.3
🇯🇵 Japan 13.3 6.6 19.8
🇺🇬 Uganda 0.0 18.0 18.0
🇨🇦 Canada 14.6 2.5 17.2
🇵🇱 Poland 0.0 15.6 15.6
🇬🇧 United Kingdom 6.5 8.9 15.4
🇹🇷 Türkiye 0.0 14.7 14.7
🇨🇿 Czechia 4.2 5.7 9.9
🇰🇿 Kazakhstan 0.0 9.6 9.6
🇮🇷 Iran 1.0 7.4 8.4
🇪🇸 Spain 7.4 0.0 7.4
🇸🇪 Sweden 7.2 0.0 7.2
🇦🇪 United Arab Emirates 5.7 0.0 5.7
🇰🇪 Kenya 0.0 5.0 5.0

This shift has major geopolitical implications. Countries that expand nuclear capacity can reduce reliance on imported fossil fuels while strengthening energy security and grid stability.

If all planned projects are completed, China will lead with 185,812 MW, followed by the U.S. at 117,910 MW and France at 75,590 MW.

France remains a historic leader in nuclear energy, with around 69% of its electricity generated from the technology.

The UK was home to the world’s first commercial nuclear power plant, which came online in 1956, but later scaled back its use of nuclear. The government is now aiming for a “golden age of nuclear,” though current commitments totaling 15,394 MW would rank the country just 12th globally.

Of the 17 countries with zero installed capacity today, Uganda is set to scale up the most to 18,000 MW, followed by Poland with 15,612 MW and Türkiye with 14,700 MW.

Betting on Nuclear Fusion and Fission

Today’s nuclear expansion is centered on fission, the technology that powers all existing reactors and accounts for about 10% of global electricity generation. While mature, it is evolving through smaller, modular designs that aim to reduce costs, improve safety, and speed up deployment.

This helps explain why much of the prospective capacity in the chart includes not only large-scale plants, but also a growing wave of smaller reactors backed by governments and private capital.

At the same time, nuclear fusion, the process that powers the sun, remains a long-term ambition. Despite rising investment and recent technical progress, it has yet to reach commercial scale.

For now, the global nuclear buildout is firmly rooted in fission, as countries prioritize reliable, low-carbon power that can be deployed within the next decade.

Mapped: Tax Burden by State in the U.S.

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.

Key Takeaways

  • Hawaii and New York have the highest tax burdens, both exceeding 12% of income.
  • Alaska and New Hampshire rank lowest, with total tax burdens below 6%.
  • Despite very different tax systems, most states fall between 8% and 10%.

How much you pay in taxes can vary dramatically depending on where you live. Across the U.S., total state and local tax burdens range from under 5% to over 13% of income.

This map ranks all 50 states by total tax burden, combining income, property, and sales taxes into a single measure.

The data for this visualization comes from a WalletHub analysis of Tax Policy Center data. Federal income taxes are excluded.

The Highest-Tax States Stand Out

Hawaii ranks first with a total tax burden of 13.3%, the highest in the country. A key driver is its heavy reliance on sales and excise taxes, which account for 7.48% of personal income, the highest share among all states.

Rank State Total Tax Burden (%)
1 Hawaii 13.3
2 New York 12.4
3 Vermont 11.1
4 New Mexico 10.8
5 Maine 10.0
6 Illinois 9.9
7 Maryland 9.7
8 New Jersey 9.5
9 Oregon 9.5
10 Rhode Island 9.3
11 California 9.2
12 Iowa 9.2

21 Massachusetts 8.8
22 Louisiana 8.8
23 Kentucky 8.8
24 Pennsylvania 8.5
25 Washington 8.5
26 Arkansas 8.4
27 Nevada 8.4
28 Virginia 8.3
29 Nebraska 8.2
30 Georgia 8.2

44 Wyoming 6.7
45 South Dakota 6.4
46 Delaware 6.3
47 Florida 6.3
48 Tennessee 6.2
49 New Hampshire 5.4
50 Alaska 4.9

New York follows at 12.4%, driven by a combination of relatively high income and property taxes. Vermont, New Mexico, and Maine round out the top five, with each above a 10% total tax burden.

Most States Fall in a Narrow Range

For most Americans, tax burdens are far less extreme. The majority of states fall between roughly 8% and 10% of income, including Illinois, Maryland, California, and Minnesota.

That clustering reflects trade-offs. States with lower income taxes often make up the difference through higher property or sales taxes, leading to similar overall burdens.

No Income Tax Doesn’t Always Mean a Low Burden

At the bottom of the ranking are states with significantly lower tax burdens, led by Alaska at 4.9% and New Hampshire at 5.4%. Several states, including Florida, Texas, and Tennessee, do not levy a state income tax.

However, no income tax does not always translate into the lowest overall burden. Many of these states rely more heavily on sales taxes or alternative revenue sources such as tourism or natural resources.

Mapped: How Currency Performance Shifted by Region in 2025

Economic health, trade flows, and financial stability—among other factors—continue to play a central role in shaping how currencies perform globally.

This graphic, developed in partnership with OANDA, breaks down how the world’s most actively traded currencies performed in 2025, offering a snapshot of currency strength across key regions.

Global Heavyweights Lose Momentum

Among developed economies, the U.S. dollar (USD) continues to dominate global FX trading, with average daily turnover reaching $8.56 trillion, according to the BIS. The euro (EUR) follows at $2.77 trillion, while the Japanese yen (JPY) remains the most traded currency in Asia.

Despite this dominance, 2025 was a weaker year for advanced market currencies overall, particularly the U.S. dollar, which fell 9.1% amid slowing economic momentum and shifting interest rate expectations.

Region Currency 2025 (% change)
North America U.S. dollar (USD) -9.1%
Middle East & North Africa UAE dirham (AED) 0.0%
South Asia Indian rupee (INR) -4.8%
Sub-Saharan Africa South African rand (ZAR) 13.5%
Europe & Central Asia Euro (EUR) 13.0%
East Asia & Pacific Japanese yen (JPY) 0.1%
Latin America & Caribbean Mexican peso (MXN) 15.3%

The euro was a notable exception, rebounding 13.0% as inflation pressures eased and growth expectations improved across the region.

Meanwhile, the Japanese yen was largely unchanged, edging up just 0.1% against the USD, reflecting continued divergence in monetary policy between the U.S. and Japan.

Emerging Markets Take the Lead

In contrast, many emerging market currencies delivered strong gains in 2025, benefiting from shifting capital flows and improving investor sentiment.

The Mexican peso led global performance, surging 15.3% against the U.S. dollar, while the South African rand followed with a 13.5% increase, highlighting renewed strength across parts of Latin America and Africa.

Not all emerging currencies advanced, however. The Indian rupee declined 4.8% against the USD, weighed down by structural challenges and capital outflows.

In the Middle East, the UAE dirham remained stable due to its peg to the U.S. dollar, effectively mirroring the greenback’s performance.

A Changing Currency Landscape

The divergence between advanced and emerging market currencies in 2025 underscores how quickly global FX dynamics can shift.

As the U.S. dollar weakened, capital rotated toward higher-yielding and previously underperforming currencies, driving strong rebounds in several emerging markets.

For investors, this environment highlights the importance of tracking relative economic strength, central bank policy direction, and exposure to commodity-driven economies.

OANDA provides access to a wide range of global currencies, helping traders navigate evolving opportunities in the foreign exchange market.

SpaceX’s IPO Would Make It a Top 10 Company Globally

SpaceX’s IPO Would Make It a Top 10 Company Globally

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.

Key Takeaways

  • At a reported valuation of $1.75 trillion, SpaceX’s IPO would place it among the world’s 10 largest companies by market value.
  • If it lists near that level, SpaceX would surpass Saudi Aramco as the largest IPO by valuation in history.
  • Elon Musk owns about 42% of SpaceX, meaning a blockbuster listing could put him on track to become the first trillionaire.

SpaceX is still private, but its reported IPO valuation target already puts it in rare territory.

At $1.75 trillion, Elon Musk’s rocket and satellite company would enter the public markets as the eighth-largest company in the world.

This visualization compares SpaceX’s targeted IPO valuation with those of the world’s largest public companies, ranked by market capitalization using data from CompaniesMarketCap and Bloomberg as of April 1, 2026.

SpaceX Valuation Big Enough for Wall Street

At a targeted valuation of $1.75 trillion, SpaceX would be worth more than all but seven of the world’s largest public companies.

The table below shows the biggest companies globally by market cap and where SpaceX would rank among them:

Rank Company Market Cap (billions, USD)
1 NVIDIA 4,280
2 Apple 3,760
3 Alphabet (Google) 3,580
4 Microsoft 2,750
5 Amazon 2,270
6 TSMC 1,780
7 Saudi Aramco 1,780
8 SpaceX 1,750
9 Broadcom 1,490
10 Meta Platforms (Facebook) 1,470
11 Tesla 1,430
12 Berkshire Hathaway 1,030
13 Walmart 996
14 Eli Lilly 858
15 Samsung 838
16 JPMorgan Chase 797

The largest U.S. companies include Nvidia, Apple, Alphabet, Microsoft, and Amazon, alongside international giants like TSMC and Saudi Aramco.

If SpaceX lists near $1.75 trillion, it would surpass Saudi Aramco’s roughly $1.7 trillion debut in 2019, making it the largest IPO by valuation in history.

For context, that valuation would be more than double the size of JPMorgan, the largest U.S. bank, and Eli Lilly, the world’s largest pharmaceutical company.

SpaceX already handles over half of all global orbital launches. In addition to its reusable rockets, it operates Starlink, the world’s largest satellite internet network.

Elon Musk: The First Trillionaire?

Musk’s path to becoming a trillionaire depends largely on his stakes in SpaceX (42%) and Tesla (12%).

A public listing near $1.75 trillion would significantly increase the value of his holdings, potentially putting him within reach of a $1 trillion net worth, depending on Tesla’s share price.

Musk is already the world’s richest person, but crossing the trillion-dollar threshold would mark a first in history—roughly equivalent to Switzerland’s annual GDP.
