The two pie charts gives the information about the number of polar bears found in four different sites namely as Churchill Study Area North, Churchill Study Area Southeast, Cape Tantam Study Area North and Cape Tantam Study Area Southeast, during a survey at Western Hudson Bay in Canada, for 1985 and 1995.
Overall, it is evident that the total number of polar bears decreased over the period. However, north area of Churchill accounted for the largest proportion, while southeast of Cape Tatnam represented the smallest share in both the years.
The largest bear proportion was attributed to Churchill study area of North, which accounted for 332 and 227 bears in 1985 and 1995 respectively of the total. This was followed by Churchilli Study area southeast with 241 bears in 1985, but this position was overtaken by Cape Tantam North area, comprising approximately 216 bears by 1995. The most significant changes in the count were observed in churchill study area southeast, while the count remained relatively stable in Cape Tatnam area north.
In contrast, the number of bears in Churchill Study area southeast represented minor share at just 70 in 1995 and the smallest segment with only 62 bears was in southeast area of Cape Tatnam.
