The pie chart provides key information about the results of a survey of polar bears recorded in four locations at Western Husdon Bay in Canada in two years,1985 and 1995.
Overall, it is clear from the graph that the number of bears decreased over the ten year period, whereas one region expercienced a minor increase in its bear population.
According to what is shown, there was a considerable drop in the total number of bears in the overall Werstern Husdon Bay area. The population fell by about a third, from 881 polar bears in 1985 to only 575 ten years later. The proportion of bears remained stable in two of the study areas, Cape Tatnam Southeast and Chuchill North.
Meanwhile, the proportion of bears found in Churchill Southeast dramatically decreased to approximately a quarter. By contrast, the number of Cape Tatnam North bears actually increased slightly over the same time period.
