The polar bear is found in the Arctic Circle and some big land masses as far south as Newfoundland. While they are rare north of 88°, there is evidence that they range all the way across the Arctic, and as far south as James Bay in Canada. It is difficult to figure out a global population of polar bears as much of the range has been poorly studied; however, biologists calculate that there are about 20,000-25,000 polar bears worldwide.(www.yygrammar.com)

Modern methods of  tracking polar bear populations have been employed only since the mid-1980s, and are expensive to perform consistently over a large area. In recent years some Inuit people in Nunavut have reported increases in bear sightings around human settlements, leading to a belief that populations are increasing. Scientists have responded by noting that hungry bears may be congregating around human settlements, leading to the illusion that populations are higher than they actually are. Of the nineteen recognized polar bear subpopulations, three are declining, six  are  stable, one is increasing, and nine lack enough data.

翻译：北极熊通常生活在北极圈以及向南最远到纽芬兰的一些大片的陆地上。虽然在北纬88°以北其较为罕见，但有证据表明，它们的活动范围甚至一直延伸到北极，向南则延伸到加拿大的詹姆斯湾。由于大部分有关其生活范围的研究还很少，所以很难统计出全球北极熊的数量；不过，生物学家计算，全世界大约有2两万到两万五千头北极熊。

翻译：跟踪北极熊种群的现代方法仅在20世纪80年代中期才被采用，而且，要在大范围内连续采用这种方法，其代价非常高昂。近年来，努纳武特的一些因纽特人报告说，在人类居住区周围看到北极熊的情况有所增加，这使人们认为其数量在增加。而科学家们的解释则是，有些北极熊由于饥饿可能会聚集在人类居住区周围（译者注：由于气候变暖，冰块提前融化，导致北极熊觅食困难。），这就导致人们产生一种错觉，误认为北极熊的数量比其实有数量要多。实际上，当前，其数量在19个公认的北极熊亚种群中，3个在下降，6个较稳定，1个在增加，9个缺乏足够的数据。
