The graph below shows the population change between 1940 and 2000 in three different counties in the U.S. state of Oregon.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
Sample answer:
The graph shows the increase in population of three counties, Columbia, Yamhill and Washington in the U.S. state of Oregon, between 1940 and 2000. In 1940, Columbia had the lowest population of the three counties, at around 25,000. This compared with about 30,000 in Yamhill and approximately 75,000 in Washington.
By 1970, Columbia’s population had risen to just under 36,000. Although this appears on the graph to be a gentle increase, it is in fact an increase of approximately 50%. Yamhill’s population also rose by nearly 50% between 1940 and 1970: from 30,000 to just under 45,000. However, the greatest real increase was in Washington, where the population in 1970 had increased by approximately 75,000, to 125,000.
The years 1970 to 2000 saw the populations of Columbia and Yamhill increase by approximately the same amounts that they had increased by the thirty years before. In 2000, Columbia’s population – at approximately 76,000 – was triple what it had been in 1940. Likewise, Yamhill’s population, at around 90,000, was almost triple what it was in 1940.
Although Washington’s increase in population between 1940 and 1970 was large, its increase in the following thirty years was even sharper, rising from about 125,000 in 1970 to more than 240,000 in 2000.
