Ranked: The 30 Largest Cities in Oceania by Population

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.

Oceania is the world’s smallest continent by land area, and the second-least populated after Antarctica.

The continent’s urban population is largely concentrated in the largest economic hubs, primarily in Australia and New Zealand.

This infographic ranks Oceania’s 30 most populated cities in 2025 using data from the UN World Population Prospects 2025.

Urban populations can be measured in different ways. In this methodology, the UN looks at satellite-mapped urban footprints for consistency. For this reason some city populations may not line up exactly as you may expect.

The 30 Largest Cities in Oceania

Here’s how the region’s largest cities stack up by population:

Rank	Country	City	2025 Population
1	Australia	Sydney	4,151,000
2	Australia	Melbourne	3,640,000
3	New Zealand	Auckland	1,123,000
4	Australia	Perth	1,079,000
5	Australia	Brisbane	1,072,000
6	Australia	Adelaide	879,000
7	Australia	Canberra	485,000
8	Papua New Guinea	Port Moresby	413,000
9	Australia	Point Cook	405,000
10	Australia	Gold Coast	299,000
11	New Zealand	Glenfield	275,000
12	New Zealand	Christchurch	261,000
13	Fiji	Suva	226,000
14	Australia	Newcastle	183,000
15	New Zealand	Hamilton	166,000
16	New Zealand	Papakura	154,000
17	New Zealand	Wellington	149,000
18	Papua New Guinea	Mendi	133,000
19	Solomon Islands	Honiara	131,000
20	New Caledonia	Nouméa	124,000
21	Australia	Dallas	122,000
22	Papua New Guinea	Lae	122,000
23	Papua New Guinea	Mount Hagen	107,000
24	Australia	Wollongong	106,000
25	Australia	North Lakes	102,000
26	Australia	Hackham West	100,000
27	Australia	Campbelltown	98,000
28	Papua New Guinea	Goroka	95,000
29	Papua New Guinea	Madang	93,000
30	French Polynesia	Papeete	92,000

Sydney’s population of 4.15 million makes it the largest metropolitan area in the region, and it has long held this title since 1975. Melbourne, Australia’s cultural capital, follows closely behind at 3.64 million.

Around 80% of Australia’s population is in the southeast due to favorable climate conditions and historically well-established ports. Perth is the only major city on the West Coast by population.

Outside Australia, Auckland stands out as the largest city in New Zealand, home to just over 1.1 million people. Other major New Zealand cities, including Christchurch, Hamilton, and Wellington, also make the top 30, but with significantly smaller populations.

Meanwhile, Papua New Guinea places six cities in the top 30, led by its capital city Port Moresby with a population of 413,000.

Oceania’s Urban Population Disparity

Most Pacific Island nations in Oceania consist of small populations spread across remote islands. On the contrary, Australia’s large landmass, infrastructure, and economic strength support multiple million-plus cities, skewing the region’s population distribution.

However, major cities in Australia are growing at a much slower rate relative to emerging cities like Mendi and Mount Hagen in Papua New Guinea, where the population is growing by more than 2% annually.

50	Kazakhstan	$320

The U.S. retains its position as the world’s largest economy with a projected GDP of $31.8 trillion in 2026, more than the next two countries combined. Despite recent changes in trade policy, U.S. real GDP is projected to grow by 2.1% in 2026, up marginally from 2% in 2025.

China ranks second at $20.7 trillion, reflecting slower but still substantial growth as it transitions toward advanced manufacturing while promoting debt sustainability and grappling with its aging population.

In Europe, Germany remains the largest economy, joined by the UK, France, and Italy among the world’s 10 largest economies. These countries are also among the world’s richest economies by GDP per capita.

Emerging Economies Climb the GDP Ladder

Many emerging markets continue to gain economic weight in 2026. India’s economy is projected to reach $4.5 trillion, making it the world’s fourth-largest economy by GDP. India’s real GDP is projected to grow fastest among major emerging economies at 6.2%, driven by strong domestic demand and expanding manufacturing capacity.

Meanwhile, countries such as Vietnam, Bangladesh, and the Philippines are projected to cross the $500 billion GDP mark, as they get increasingly integrated into global supply chains.

States With the Highest Number of Households With No Income

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.

Roughly one in four U.S. households are classified as having “no income” under Census Bureau definitions. Overall, this category often includes retirees, unemployed individuals, and people with disabilities.

In total, households with no income number 33.1 million nationwide, a figure shaped in part by an aging population and a poverty rate of 10.6% as of 2024. While the definition remains somewhat opaque, it highlights the scale of American homes without regular wage or salary income.

This graphic shows the number of households by U.S. state with no income, based on data from the Census Bureau’s American Community Survey 2024 1-Year Estimates.

California Leads Nationally in Households With No Income

California, the country’s most populous state, has 3.1 million households with “no-income”.

Though this is the highest number in absolute terms, its percentage of low income households (23%) is actually below the national average.

As we can see, Florida ranks in second, with 2.6 million residents reporting no income. This accounts for 29% of the state’s population, likely influenced by having the second-highest share of people over age 65 in America, after Maine.

When it comes to the state with the highest share overall, West Virginia leads the country, with over one in three falling in this category. Not only does it have one of the highest poverty rates in the country, over a fifth of the population is over 65.

Meanwhile, Utah has the lowest rate (17%) in the country.

Ranked: Countries With the Biggest Change in Life Expectancy

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.

Back in 1965, the average life expectancy globally was 54 years, and has since risen by about 20 years as of 2025.

Nearly every country has seen gains over this period, though a small group has far outpaced the global average, adding more than three decades to life expectancy. To put this in perspective, America has seen roughly a nine year increase in life expectancy over six decades.

This graphic shows which countries have gained the most in life expectancy since 1965, based on data from Our World in Data and the United Nations.

Where Change in Life Expectancy Accelerated the Most

Here are the countries with the biggest increases in period life expectancy, which indicates how long a newborn would live on average, given the death rates of that year.

China	53	79	26

The Maldives leads globally, with average life expectancy increasing by 41 years since 1965 to reach 82 in 2025.

Like the Maldives, several countries in Asia have seen lifespans extend notably. In 1965, average life expectancy in Afghanistan was 35 years, and has now risen to 67. India, meanwhile, has seen average lifespans increase by 27 years amid growing economic expansion and advancements in healthcare.

When you look across Africa, Algeria has witnessed the strongest gain in life expectancy overall. In 2025, the average stands at 77 years—up from 43 in 1965— sitting among the highest in Africa. Going further, nine African countries have added at least 27 years to their life expectancy.

As we can see, China also ranks among the top countries by change in life expectancy, with a gain of 26 years since 1965. On average, this equaled a 22-week increase in life expectancy per year during a time of rapid economic transformation.

Mapped: Global Inflation by Country 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 incredible data-driven charts from a variety of trusted sources.

Global inflation fell moderately to 4.2% in 2025, in spite of U.S. tariffs hitting century highs.

For 2026, the IMF projects inflation to decline even further to 3.7% in 2026, even as tariff impacts continue to materialize. This is being driven by weak price growth in China and below-target inflation in many European countries.

This graphic shows inflation by country in 2025, based on data from the IMF’s latest World Economic Outlook.

Venezuela faces the highest inflation on the planet, at 269.9% in 2025, and this is set to jump to 682% in 2026.

Over 2025, the Venezuelan bolivar depreciated 82.7% against the dollar as U.S. sanctions and warship deployment targeting alleged drug traffickers contributed to inflationary pressures. Now, with Maduro’s ouster, the outlook for the economy remains uncertain.

For the U.S., inflation stood at 2.7% and is forecast to fall to 2.4% in 2026. Overall, tariffs were estimated to increase inflation by 0.5 percentage points in 2025, far lower than initially feared.

China, on the other hand, saw inflation sit at 0.0%, one of the lowest rates globally. Deflationary pressures, from excess production to a weak labor market, significantly impacted the economic climate. In 2026, inflation is set to rise to 0.8% fueled by economic stimulus measures that aim to boost domestic consumption.

Meanwhile, several European economies saw moderate inflation in 2025 amid low energy and import prices. In France, inflation stood at 1.1%, while Italy and Germany saw rates of 1.7% and 2.1%, respectively.

How Venezuela’s Oil Reserves Compare to the Rest of 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.

Venezuela sits atop the largest oil reserves on the planet, yet its role in global energy markets is far smaller than in past decades.

While countries like the United States and Saudi Arabia dominate daily oil production, Venezuela’s output has steadily declined over the past several decades.

This visualization compares proven oil reserves across major producing countries. Reserves represent the volume of oil that can be economically produced under current conditions. The data for this visualization comes from OPEC’s Annual Statistical Bulletin 2025.

Venezuela’s Unmatched Reserve Base

Venezuela holds an estimated 303 billion barrels of proven oil reserves, the largest of any country and well ahead of Saudi Arabia. These reserves account for roughly 17% of the global total.

Most of this oil is concentrated in the Orinoco Belt, where deposits are predominantly heavy crude. While abundant, this type of oil is more expensive to produce and requires specialized infrastructure.

Despite its reserve dominance, Venezuela ranked just 21st in oil production in 2024, producing about 960,000 barrels per day.

At its peak in the 1970s, the country pumped as much as 3.5 million barrels per day, representing more than 7% of global output at the time. Production fell sharply during the 2010s and averaged roughly 1.1 million barrels per day last year, or about 1% of global production.

Politics, Sanctions, and Investment Challenges

Decades of mismanagement, underinvestment, and international sanctions have constrained Venezuela’s oil sector.

Although some Western firms, including U.S.-based Chevron, continue to operate in the country, their presence has diminished significantly as sanctions expanded and exports were targeted.
