Band 6+: You should spend about 20 minutes on this task. 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

The line chart compares the population of three countries in the state of Oregon over the 60-year period from 1940 to 2000.

It is clear that the total number of people living in Washington was the largest among the three countries, while Columbia and Yamhill were close to each other. All three countries experienced a rise in population over the 60-year timespan.

In 1940, there were 75,000 people living in Washington, and the figure increased to slightly over 120,000 after 30 years. The population of Yamhill and Columbia were around 30,000 in the beginning of the period, and the figures rose to about 45,000 and 30,000 respectively in 1970. Thus the gap between the two numbers became larger.

During 1970 and 2000, Washington experienced the fastest increase in population, and ended up with over 240,000 people in 2000. The population for Yamhill and Columbia rose gradually, being around 75,000 and 60,000 in the end respectively. The gap between the two figures did not vary over this 30-year period.
