Here's a more recent finding from 2017;

..Dr Susan Crockford, a Canadian wildlife expert, documents the latest findings about rising polar bear numbers.

In 2005, the official global polar bear estimate was about 22,500.

Since 2005, however, the estimated global polar bear population has risen by more than 30% to about 30,000 bears, far and away the highest estimate in more than 50 years..

And here's the very latest posted today;

The bottom line: it is scientifically unacceptable for the PBSG to continue to refuse to provide an extrapolated ‘best guess’ global estimate for polar bears, given that the scientifically accurate estimate they crave is essentially unattainable. An estimate of about 39,000 (range 26,000-58,000) at 2018 is not only plausible but scientifically defensible.
