Polar Bear Population Graph 2025 Population Graph. How Many Polar Bears Left In The World Polar Bear Population SciQuest In the 1960s and 1970s, scientists used surveys, capture and release, local knowledge and other methods to estimate polar populations The global polar bear population is estimated to be 20,000-31,000 individuals as of 2023, shared between all countries included in the species' range: Canada, Greenland, Norway, Russia, and the United States, as well as in.

Those efforts have been a conservation success story: from a population estimated at about 12,000 bears in the late 1960s, numbers have almost tripled, to just over 32,000 in 2023 Long term change: ≥2 polar bear generations (≥23 yr) Short term change: ~1 polar bear generation

Figure 1 from Polar bear population status in the northern Beaufort Sea, Canada, 19712006. Use of freshwater/glacial ice during summer and fall means that the sea ice metric used for other subpopulations may not be biologially relevant for Southeast Greenland. From the 1980s onwards, scientists have complemented these methods with satellite tracking and genetic data to better understand polar bear population estimates.
