If Antarctica were a sovereign nation, it would be the second-largest country on Earth by area, yet one of the smallest by population, with an economy almost entirely dependent on science funding and tourism. It’s a fun thought experiment, but it also reveals why the continent’s current arrangement, a shared international space governed by treaty, exists in the first place.
Size and Territory
Antarctica covers roughly 14.2 million square kilometers, making it about twice the size of Australia and fifty times the size of the United Kingdom. Only Russia, at 17.1 million square kilometers, would be larger. As a country, Antarctica would stretch across more land than China, the United States, and India individually.
But almost all of that land is buried under ice. Only about 0.4% of the continent is ice-free rock, mostly concentrated in coastal areas and the McMurdo Dry Valleys. The habitable land of this hypothetical country would be roughly the size of a small Caribbean island nation, scattered across a continent-sized ice sheet. Building cities, roads, or farms on shifting glacial ice isn’t realistic, so the usable territory would be vanishingly small.
Population and Governance
Antarctica has no permanent residents. Around 1,000 to 5,000 people live there at any given time, depending on the season, almost all of them scientists and support staff rotating through roughly 70 research stations. In summer, the population swells. In winter, it shrinks to a skeleton crew. A country of 5,000 people would be smaller than the Vatican, which has about 800 residents but sits within Rome’s infrastructure.
Governing this population would be uniquely challenging. The stations are operated by over 30 different nations, and the people living in them answer to their home governments. There’s no shared language, no indigenous population, no cultural identity that would bind citizens together. Any Antarctic government would need to figure out who qualifies as a citizen when nobody is born there (with a handful of symbolic exceptions) and almost nobody stays longer than a year or two.
Why It Isn’t a Country Already
Seven nations have formally claimed slices of Antarctica: Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom. Some of these claims overlap, particularly those of Argentina, Chile, and the UK on the Antarctic Peninsula. One large section, Marie Byrd Land, has never been claimed by anyone.
The Antarctic Treaty, signed in 1959 and now backed by over 50 countries, froze all territorial claims in place. No nation can enforce its claim, establish military bases, or assert sovereignty. The treaty essentially set Antarctica aside for peaceful scientific research, sidestepping what could have become a serious geopolitical conflict during the Cold War. Turning Antarctica into a single country would require dismantling this framework and convincing seven claimant nations to abandon their positions, something none of them have shown interest in doing.
The Economy Problem
A country needs revenue, and Antarctica has almost no way to generate it. The continent’s economy, such as it is, runs on two things: government-funded research and tourism. The U.S. alone spends roughly $285 million per year just on polar facilities and logistics to keep its Antarctic stations running. That money flows in from taxpayers abroad, not from any domestic economic activity.
Tourism is the closest thing to a private sector. Visitor numbers have grown from about 8,000 per year in the early 1990s to 105,000 in 2022-2023, generating an estimated $820 million annually. That sounds meaningful until you compare it to even the smallest island economies. Bermuda, with 64,000 residents, brings in over $500 million from tourism alone while also hosting a major insurance industry. Antarctica’s tourism revenue would place it among the world’s poorest nations on a per-capita basis, and that money largely flows to tour operators based in Argentina, Chile, and other departure countries, not to Antarctica itself.
Mineral Wealth You Can’t Touch
Antarctica is believed to hold significant deposits of coal, iron ore, and possibly oil and natural gas beneath its ice sheet. In theory, these resources could power a national economy. In practice, they’re locked away by both geography and law.
The Madrid Protocol, adopted in 1991 as an addition to the Antarctic Treaty, bans all mineral resource activities on the continent. There is no expiration date on this ban. Until 2048, changing it requires unanimous agreement from every consultative party to the treaty. After 2048, modification becomes slightly easier procedurally but still demands broad consensus. Even if the ban were lifted, the cost of drilling through kilometers of ice in extreme cold, then transporting extracted resources thousands of kilometers to market, would make most operations economically unviable compared to deposits elsewhere.
Freshwater: The Hidden Asset
Antarctica’s ice sheet holds about 70% of all the freshwater on Earth. In a world increasingly worried about water scarcity, this sounds like an extraordinary national resource. Proposals to tow Antarctic icebergs to arid regions have circulated since the 1970s, and a few have been semi-seriously explored by Middle Eastern countries.
The logistics remain daunting. An iceberg large enough to be worth towing would weigh millions of tons and take months to reach a destination like Cape Town or Dubai, losing significant mass to melting along the way. No one has done it at commercial scale. If Antarctica were a country, it would theoretically control the largest freshwater reserve on the planet but lack any practical way to monetize it with current technology.
Strategic and Environmental Power
What makes this thought experiment genuinely interesting is not economics but influence. An Antarctic nation would control a continent that regulates global climate. The Southern Ocean surrounding Antarctica drives ocean circulation patterns that distribute heat across the planet. The ice sheet’s reflective surface bounces solar radiation back into space, helping regulate global temperatures. If that ice melted entirely, global sea levels would rise by roughly 58 meters, redrawing coastlines worldwide.
This gives a hypothetical Antarctic country enormous leverage. Decisions about environmental protection, ice sheet management, and access to surrounding fisheries would carry global consequences. The Southern Ocean is already one of the world’s most productive fishing grounds, particularly for krill, which forms the base of the Antarctic food web. A sovereign Antarctica could charge fishing fees, restrict access, or negotiate climate agreements from a position of unique environmental power.
In reality, this is precisely why the current system exists. No single country can be trusted with that much influence over the global environment. The Antarctic Treaty keeps the continent as a shared responsibility, governed by consensus rather than sovereignty. It’s an imperfect system, but the alternative, one nation controlling 70% of Earth’s freshwater and the stability of its coastlines, is a scenario the rest of the world has strong reasons to prevent.
