Where Population Growth Has Been Fastest Since 2000

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.

The world’s population grew by more than 2 billion people between 2000 and 2025, but that growth has varied significantly across countries.

This chart compares the countries with the fastest population growth over that period, measured by both percentage increase and total people added, using IMF data.

While smaller Gulf nations dominate in percentage terms, the largest population gains come from countries like India, Nigeria, and Pakistan, highlighting a divide between relative growth and absolute impact.

The data reveals a key split: countries leading in percentage growth are often smaller economies, while those adding the most people are already among the world’s most populous.

The Most Populous Country in History

India’s population growth since 2000 stands apart in scale.

The country added 406 million people in just 25 years, more than the population of the United States, making it the largest population increase of any country in modern history.

This represents 38% growth over its population in 2000, which had already topped one billion. In 2023, India surpassed China to become the world’s most populous country, a position it is unlikely to lose anytime soon.

Rank	Country	Population growth in millions (2000-2025)
1	India	406
2	China	138
3	Nigeria	113
4	Pakistan	105
5	Indonesia	78
6	United States	59
7	Democratic Republic of the Congo	59
8	Ethiopia	50
9	Bangladesh	46
10	Egypt	45
11	Brazil	39
12	Philippines	37
13	Tanzania	35
14	Mexico	34
15	Uganda	26
16	Iran	24
17	Kenya	24
18	Angola	23
19	Vietnam	23
20	Yemen	22
21	Türkiye	22
22	Sudan	19
23	South Africa	19
24	Mozambique	18
25	Saudi Arabia	18

Today, nearly a fifth of the world’s population lives in India, despite the country occupying roughly 2.5% of the world’s land area. This surge has made India the most populous country in recorded history.

In recent years, population growth has slowed in the South Asian giant, raising concerns that it could follow China in facing a demographic slowdown earlier than expected.

Population Booms in the Persian Gulf

While Asia leads in total population gains, the fastest growth rates are concentrated in the Persian Gulf.

Between 2005 and 2025, countries such as Bahrain (154%), Kuwait (139%), and the United Arab Emirates (250%) recorded some of the highest growth rates globally. With 423% growth, Qatar leads the world in population growth since 2000.

The following data table lists the 25 fastest-growing countries by percentage change in population since 2000.

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%
25	Burkina Faso	102.3%

The Gulf states’ population surges are driven largely by imported labor supporting construction and energy booms. Today, less than 15% of Qatar’s population consists of citizens, with the majority made up of foreign-born workers, particularly from South Asia.

Africa: The Next Population Hotspot

Africa is emerging as the center of global population growth.

More than two-thirds of the fastest-growing countries by percentage are located on the continent, with several nations already doubling their populations since 2000.

This growth has been driven by rising life expectancy and lower infant mortality, even as fertility rates remain high. The continent is projected to surpass 2 billion people by 2038, with some regions expected to more than quintuple in population over the 21st century.

West Africa is one such region. With a population exceeding 400 million, about half of whom live in Nigeria, it is projected to become one of the most densely populated areas in the world in the coming decades.

Mapped: Grocery Prices Across U.S. States

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.

Hawaii and Alaska have the highest grocery costs in the U.S., with prices more than 25% above the national average.

Using data from the Missouri Economic Research and Information Center, this map ranks grocery prices across all 50 states relative to a U.S. baseline of 100.

While Hawaii and Alaska are far above average due to shipping costs and geographic isolation, many Southern states offer the lowest prices, highlighting how regional cost structures shape what Americans pay at the checkout.

This variation comes at a time when food prices remain a top concern for consumers, with grocery costs still elevated compared to pre-pandemic levels.

Ranked: States With the Highest Grocery Prices

Hawaii and Alaska stand apart, with grocery prices 31.4% and 25% above the national average.

Their geographic isolation means both states rely heavily on imported goods, making transportation a key driver of higher costs. For a typical household spending $8,000–$10,000 per year on groceries, this price gap can translate into an extra $2,000 or more annually in the most expensive states.

The table below shows each state’s grocery price index, based on 2025 annual averages benchmarked to a U.S. baseline of 100:

California’s grocery prices are 9.3% above the U.S. average, ranking third among all states.

Despite its massive agricultural output, California’s grocery prices remain elevated due to high labor, energy, and real estate costs. Washington faces similar pressures, along with some of the highest fuel costs in the country.

A cluster of Northeastern states—Vermont, Maryland, and Washington, D.C.—also rank among the most expensive, with grocery prices 5–6% above average. Vermont’s low population density increases transportation costs, while Washington, D.C.’s high commercial rents and wages push prices higher.

Florida ranks ninth for grocery costs, despite a more moderate cost of living. A relatively concentrated grocery market gives dominant players greater pricing power, while its tourism industry keeps demand elevated, both contributing to above-average food prices.

The Least Expensive Grocery Prices in America

Arkansas has the lowest grocery prices in the U.S., at 5.7% below the national average—marking a sharp contrast with the country’s most expensive states.

It is followed by Southern states like Texas, Oklahoma, and Mississippi, where grocery prices are often 5–10% below the national average, well below many coastal and non-contiguous states.

These states also have a lower overall cost of living, meaning housing, fuel, and groceries take up a smaller share of household budgets overall.

Mapped: Europe’s Homeownership Divide

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.

Homeownership in Europe shows a stark contrast: in some countries, more than 9 in 10 households own their homes, while in others, fewer than half do.

That gap is not driven by income alone. In fact, some of Europe’s richest economies, like Germany and Switzerland, have the lowest ownership rates, where renting is far more common.

This map uses the latest available data from Eurostat and the UK Parliament to show how homeownership varies across Europe by share of households.

Why this matters: Homeownership is closely tied to wealth building, financial security, and long-term stability. Countries with lower ownership rates often have more developed rental markets, while higher rates can reflect historical policies rather than current affordability.

Europe’s Highest Homeownership Rates

The highest homeownership rates on the Old Continent are found in the eastern half of the European Union, led by Romania (93.2%), Slovakia (93.1%), and Croatia (91.4%).

On average, countries in Central and Eastern Europe have homeownership rates roughly 30% higher than their peers in Western Europe.

The following data table lists European countries alongside their household homeownership rate.

Rank	Country	Homeownership Rate by share of households (%)
1	Romania	93.2
2	Slovakia	93.1
3	Croatia	91.4
4	Hungary	89.8
5	Lithuania	87.4
6	Poland	87.2
7	Bulgaria	86.1
8	Latvia	82.2
9	Norway	80.0
10	Estonia	79.7
11	Italy	77.1
12	Czechia	75.1
13	Slovenia	74.2
14	Spain	73.6
15	Portugal	71.2
16	Belgium	70.9
17	Greece	69.4
18	Ireland	69.3
19	Cyprus	69.2
20	Netherlands	68.8
21	Malta	68.1
22	Finland	66.9
23	Sweden	64.6
24	Luxembourg	63.5
25	UK	61.7
26	France	61.2
27	Denmark	60.9
28	Austria	54.5
29	Germany	47.2
30	Switzerland	42.0
--	EU	68.4

A major driver of Eastern Europe’s high ownership rates is the mass privatization of housing in the 1990s. As governments sold off state-owned apartments, often at steep discounts, millions of residents became homeowners, creating a structural gap with Western Europe that persists today.

Homeownership in Western Europe

In contrast, Western Europe tends to have lower homeownership rates on average, including roughly 61.5% of households in France and the United Kingdom and approximately 68% across the Benelux countries.

In Western Europe, higher home prices and stricter lending standards have made ownership less accessible, especially for younger generations. At the same time, strong tenant protections and stable rental markets make long-term renting a more common and viable alternative.

Meanwhile, dynamic labor markets in major cities have also contributed to the growth of large rental markets, where property owners rent to working professionals and young families.

The Germanic Outliers

Low homeownership rates are most pronounced in the DACH region (Germany, Austria, and Switzerland), where high incomes and strong economies coexist with some of the lowest ownership levels in Europe.

In Switzerland, one of the wealthiest countries in the world, only 42% of households own the home in which they live. Germany similarly sees less than half of households classified as owner-occupiers (47.2%), while neighboring Austria is only slightly higher at 54.5%.

These countries’ low rates relative to the rest of Europe can be partly explained by cultural factors, such as young adults leaving home earlier than in Southern Europe. In addition, the post-socialist transition in places like East Germany followed a different path, with state-owned housing often sold to corporations rather than residents during the 1990s.

Ranked: The Most Productive Countries in the World

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.

Not all hours worked generate the same economic value.

This chart ranks OECD countries by GDP per hour worked, a common measure of productivity. The gap at the top is striking: Ireland produces over 50% more per hour than most advanced economies.

However, these figures come with an important caveat. In countries like Ireland and Luxembourg, productivity is significantly boosted by multinational firms shifting profits, which can inflate GDP relative to actual domestic output.

Using data from the OECD, this visualization highlights where workers appear most productive—and what drives those differences.

GDP per Hour Worked by Country

With output per hour at $151 in purchasing power parity-adjusted dollars, Ireland stands well above its peers.

This table shows GDP per hour worked by country in 2023, in PPP-adjusted dollars, which account for differences in cost of living:

Country	GDP Per Hour Worked Purchasing Power Parity Dollars
Ireland	$151
Norway	$132
Luxembourg	$125
Belgium	$100
Switzerland	$99
Denmark	$99
United States	$97
Austria	$95
Iceland	$95
Netherlands	$94
Germany	$94
Sweden	$90
France	$88
Finland	$83
Australia	$79
United Kingdom	$79
Italy	$77
Canada	$75
Spain	$73
Slovenia	$66
Israel	$61
Czechia	$60
Lithuania	$60
Slovak Republic	$60
Portugal	$59
Japan	$56
Latvia	$56
New Zealand	$55
Korea	$55
Hungary	$54
Poland	$54
Estonia	$53
Greece	$45
Chile	$37
Costa Rica	$32
Mexico	$25
Colombia	$21
OECD Average	$71

Ireland’s productivity is heavily influenced by the presence of multinational corporations, particularly in tech and pharmaceuticals. For perspective, Ireland’s productivity drops by 31% to $115 when using gross national income (GNI) as an alternative measure.

Norway ($132) and Luxembourg ($125) also benefit from distinct structural advantages. Norway is supported by its energy sector, while Luxembourg’s finance industry significantly boosts its output. Similarly, Luxembourg’s productivity drops by 54% when measured using GNI.

Countries with a higher concentration of capital-intensive or knowledge-based industries, such as technology, finance, and pharmaceuticals, tend to generate more value per hour.

Meanwhile, economies with larger shares of agriculture, tourism, or lower-value services typically report lower productivity levels.

This helps explain why countries like the U.S. ($97) and Germany ($88) rank above the OECD average of $71, given their strong industrial and innovation-driven sectors, while others fall further down the list.

Every S&P 500 Company in One Giant Chart

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.

What does the entire S&P 500 actually look like?

This visualization brings all 500 companies into a single view, with each sized by its share of the index and grouped by sector. It is based on data from Slickcharts as of March 30, 2026.

Each circle represents a company, making it easy to compare how market value is distributed across sectors—and to see which firms dominate the index.

One immediate takeaway is how much space is occupied by just a handful of companies. Just 10 firms now make up over 36% of the S&P 500, up from 23% in 2000.

Ranked: The Top S&P 500 Companies by Index Weight

Nvidia is now the largest company in the S&P 500, with a 7.0% index weight—larger than entire sectors like energy or utilities.

Apple follows with a 6.3% share, while Microsoft ranks third at 4.6%. These three companies account for about 18% of the S&P 500’s total value, while AI-driven firms represent 10 of the top 20 largest companies.

This table ranks every company in the S&P 500 by index weight as of March 30, 2026:

Berkshire Hathaway is the only financials company in the top 10 by market cap, with its ranking falling from sixth to 10th place since 2023. By contrast, Walmart has climbed to 11th from 29th in just two years amid strong online sales.

Among health care firms, Eli Lilly (#12) has overtaken UnitedHealth Group (#42) as the most valuable company, fueled by sales of its weight-loss drugs.

Why This Concentration Matters

While the top 10 companies’ share of the index has edged down from 41% in 2025, its still-elevated concentration relative to historical levels has real implications:

• Diversification is shrinking: Index investors are more exposed to a handful of companies than at previous market-cycle peaks
• Market performance is narrowing: A small group of firms is increasingly driving overall returns
• The index is evolving: The S&P 500 may no longer broadly reflect the U.S. economy

In effect, the market is behaving less like a 500-company index, and more like a concentrated bet on a few dominant firms. At the center of this shift is the AI boom, illustrating how a single technological wave is reshaping the market’s hierarchy.

Mapped: The Salary Needed to Live Comfortably in U.S. Cities

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.

How much do you need to earn to live comfortably in a major American city? Increasingly, the answer is a six-figure salary.

This map shows the income required for a comfortable lifestyle across 56 U.S. cities, factoring in housing, food, transportation, savings, and discretionary spending.

The data comes from SmartAsset, using the MIT Living Wage Calculator and updated in February 2026.

The Highest-Cost Cities Now Require Nearly $160K

New York tops the list at $158,954, narrowly ahead of San Jose at $158,080.

California accounts for many of the highest-cost cities overall, with Irvine, San Diego, San Francisco, Oakland, Los Angeles, and Sacramento all ranking near the top.

Taken together, the top of the ranking highlights how concentrated the highest costs are in a handful of major metros, particularly in California and the Northeast.

Boston, Honolulu, Seattle, and Jersey City also stand out, showing that the highest salary thresholds extend well beyond just a handful of coastal hubs.

Six-Figure Salaries Are Becoming the Norm

A key shift in the data is how quickly six-figure income requirements have spread beyond the most expensive cities.

Beyond the usual high-cost leaders, cities such as Denver, Atlanta, Nashville, Charlotte, and Boise now require roughly $100K or more for a comfortable lifestyle. That shift suggests higher living costs are no longer confined to the country’s most expensive coastal markets.

Lower-Cost Cities Still Require Substantial Income

At the lower end of the ranking, the salary needed to live comfortably still remains substantial. San Antonio has the lowest threshold at $83,069, followed by Memphis at $86,444 and Tulsa at $87,690.

Even in the most affordable cities on the map, the income needed for a comfortable lifestyle is far above what many households earn, highlighting how even the most “affordable” major cities now require incomes that were once considered high.
