Every source I find shows the populations have decreased since at least 1977 except in the Davis Strait which has banned seal hunting. Even in areas where polar bear hunting is legal they say the increased birth rates have not kept up with the mortality rates.
In addtion, the average weight of the polar bears is decreasing. Why would the WCU put them on the Threatened list and the US is considering putting them on the Endangered list if they were increasing so much???
The estimated population was 25-40,000 in 1993 and today is 20-25,000. Surveys I have seen (not using any sites that complain about global warming) show the population has decreased 22% since 1980.
