  4. Based on subpopulation estimates, and presumed densities in areas where numbers are unknown, as of 2015 the IUCN/SSC PBSG esti­mates that there are approximately 22,000–31,000 polar bears across the Arctic. The current range covered by these subpopulations represents a total land and marine area of approximately 23 million km2.
