IELTS-TASK1 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. The line graph illustrates the trends for population from 1940 to 2000 in three counties of Oregon in America, namely Columbia, Yamhill and Washington. It is clear that the figures for all of the three counties had a main tendency of increase during the examined period. Overall, the Washington County had the most population over the 60 years. Staring with around 75 thousand in 1940, the figure for Washington County increased gradually to approximately 125 thousand by 1970. From then on, the population rose significantly to almost double times as many as that in 1970 after 30 years. The population of Columbia County and Yamhill County saw a similar pattern over the period of 60 years. The figures for these two counties accounted for roughly 28 and 30 thousand respectively in 1940. After a thirty-year increase, these two numbers rose to around 37 and 45 thousand respectively. Later, the two counties saw a parallel increase, and the figures finally stood at about 75 and 90 thousand respectively in 2000.
