You probably just want a quick answer, so here goes: There are about 20,000 to 30,000 polar bears left in the wild today. Scientists pulled this estimate together from surveys all over the Arctic. It gives you a sense of how many polar bears are still out there.
Let’s talk about where polar bears actually live, why sea ice matters so much, and what’s chipping away at their habitat. That context really helps when you start looking at what conservation efforts can do for their future.
How Many Polar Bears Are Left in the World?
Let’s get into the numbers and where these bears actually live. Scientists and experts pull together estimates from surveys, but depending on the year and the methods, you’ll see some variation.
Latest Global Polar Bear Population Estimates
Right now, researchers estimate there are about 22,000 to 31,000 wild polar bears worldwide. They base this on surveys and expert reviews that track subpopulations. Zoos and aquariums also hold about 300 bears, but those aren’t included in the wild count.
Some subpopulations have recent surveys, while others don’t, so the numbers aren’t perfect. The IUCN Polar Bear Specialist Group posts updated tables when they get new data. Scientists use different methods—like genetic recapture, aerial counts, and distance sampling—so you’ll see a range of uncertainty.
Think of the global number as a best guess, not a precise figure. Some regions have stable or even rising counts, but others are seeing numbers drop as sea ice disappears.
Distribution Across Regions and Subpopulations
Polar bears roam across the Arctic in about 19 to 20 recognized subpopulations. Most live in Canada, but you’ll also find plenty in Russia, Greenland, Norway (Svalbard/Barents Sea), and the United States (Alaska).
Some well-known areas include:
- Western Hudson Bay (Canada)
- Southern and Northern Beaufort Sea (Alaska and Canada)
- Chukchi Sea (Russia/Alaska)
- Svalbard / Barents Sea (Norway/Russia)
- East Greenland and Wrangel Island (Russia)
- Kane Basin and other Canadian Arctic spots like Nunavut
Where a bear lives matters a lot. Sea-ice changes can hit some areas harder than others. Local surveys usually focus on a specific subpopulation, not all polar bears.
Current Status of Key Polar Bear Populations
Trends really depend on the subpopulation. For example, Western Hudson Bay has dropped in recent years as ice breaks up earlier and bears go longer without it. The Southern Beaufort Sea has had declines too.
Other places, like some parts of Svalbard/Barents Sea and Russian regions, seem more stable or just uncertain. The IUCN Polar Bear Specialist Group keeps tabs on each subpopulation’s latest numbers and trends. Local hunting rules and management also play a role—like quotas in Nunavut or different reporting in Greenland.

Major Threats and Conservation of Polar Bears
Polar bears have a lot stacked against them: shrinking sea ice, declining health, trouble raising cubs, more run-ins with people, and a whole patchwork of laws trying to help.
Impact of Climate Change and Arctic Sea Ice Loss
The biggest threat? It’s the vanishing Arctic sea ice. Greenhouse gas emissions warm the air and water, pushing ice to form later and melt sooner. That means polar bears lose precious hunting time when they’d normally catch ringed seals.
With less ice, bears have to swim farther or end up on land, where food is even harder to find. Some high-Arctic groups still get ice most of the year, but others—like Southern Hudson Bay—are already losing weight and numbers. Scientists warn that if warming keeps up, most sea ice outside the far north could disappear by 2100.
You can keep tabs on which subpopulations are shrinking, stable, or uncertain through the IUCN Polar Bear Specialist Group and other conservation groups.
Declining Body Condition and Cub Survival
The first thing you’ll notice is polar bears getting thinner. When bears hunt less, adult females don’t build up enough fat for spring. Thinner mothers have smaller litters and less milk for their cubs.
Fewer cubs make it through their first year when mothers can’t keep up. In some places, longer stretches without ice mean mothers fast on land for months, burning through their fat reserves. That slows down reproduction and makes it tough for populations to bounce back. Researchers track weight, blood markers, and cub numbers to spot problems early and adjust management.
Human-Wildlife Conflict and Illegal Hunting
As sea ice shrinks, bears spend more time near people. They raid garbage, camps, and even fuel stores, which raises safety risks for both sides. Sometimes people shoot bears to protect themselves or their property.
Illegal hunting and poorly managed harvests add to the pressure in a few spots. Indigenous communities in Canada, Alaska, Greenland, and Russia have legal, managed harvests. Conflict-reduction efforts—like bear-proof dumpsters, electric fences, and trained response teams—can help keep everyone safer and cut down on bears being killed.
Laws, Agreements, and Conservation Efforts
We can look at a mix of laws and international agreements that actually protect polar bears. Back in 1973, the Agreement on the Conservation of Polar Bears set some ground rules for hunting and research among the countries where polar bears live.
In the U.S., the Endangered Species Act and the Marine Mammal Protection Act step in to provide legal protection. These laws also guide how we plan for polar bear recovery.
Groups like Polar Bears International and WWF jump in by funding research. They also try to cut down on industrial threats and team up with Arctic communities.
Protected areas and restrictions on oil and gas development help keep sea ice habitat and denning grounds safe. But honestly, global action on greenhouse gas emissions is still the key—cutting emissions slows down sea ice loss and gives polar bears a real shot at a future.
