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 thatthey 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 beenpoorly studied; however, biologists calculate that there are about 20,000-25,000 polar bears worldwide.
Modern methodsoftracking polar bear populations have been employed only since the mid-1980s,and are expensiveto 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, sixare stable, one is increasing, and nine lack enough data.
翻译：北极熊一般生活在北极圈与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。因为大多数有关其生活范围的研究还极少，所以非常难统计出全球北极熊的数目；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办法仅在20世纪80年代中期才被使用，而且，要在大范围内连续使用这种办法，其代价特别高昂。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状况有所增加，这使大家觉得其数目在增加。而科学家们的讲解则是，有的北极熊因为饥饿或许会聚集在人类居住区周围（译者注：因为气候变暖，冰块提前融化，致使北极熊觅食困难。），这就致使大家产生一种错觉，误觉得北极熊的数目比其实有数目要多。事实上，目前，其数目在19个公认的北极熊亚种群中，3个在降低，6个较稳定，1个在增加，9个缺少足够的数据。
