The World Wildlife Foundation estimates that there are between 20,000 and 25,000 polar bears left in the world. Between 60 and 80 percent of these animals live in Canada.
Worldwide, the polar bear population is considered vulnerable. This means that the species is likely to become threatened if circumstances do not improve. Specifically, the polar bear populations of Denmark, Greenland and Norway are vulnerable. The status of Russia's polar bear population is uncertain but possibly improving. In the United States, polar bears are a threatened species. This indicates that there is a real possibility that they may become extinct. The number of polar bears in Canada varies by location. Some areas are stable, while others are losing numbers.
