Sample Answer 1
The line graph illustrates the population change in the US state of Oregon across three counties—Columbia, Yamhill, and Washington—from 1940 to 2000.
Overall, Washington County experienced the most significant population growth, especially after 1980, whereas Columbia and Yamhill showed a steady yet much slower increase over the years. Washington's population surged far ahead of the other two counties by the end of the period.
In 1940, Columbia's population stood at approximately 28,000, the smallest among the three counties. Yamhill followed closely with around 30,000 residents, while Washington had a significantly larger population of 75,000. By 1970, both Columbia and Yamhill had grown modestly, each reaching about 45,000 to 50,000 residents, marking an increase of roughly 50% in three decades. In contrast, Washington County's population saw a sharper rise, almost doubling to reach around 125,000.
By 2000, the population trends further diverged. Columbia and Yamhill saw noticeable increases, with Columbia reaching approximately 90,000 and Yamhill around 80,000. However, Washington experienced exponential growth, climbing to nearly 250,000 residents, more than doubling its 1970 figure and solidifying its position as the most populous county among the three. This data reflects a striking disparity in population dynamics across these counties within the given period.
Sample Answer 2
The line graph depicts the population change in the US state of Oregon across three counties—Columbia, Yamhill, and Washington—over a 60-year period from 1940 to 2000.
At a glance, Washington County experienced a remarkable population surge, particularly after 1970, whereas Columbia and Yamhill exhibited slower, steady increases. By the end of the period, Washington had a significantly larger population than the other two counties.
In 1940, Columbia and Yamhill started with relatively low populations, each close to 30,000 residents, while Washington had a much higher count, around 75,000. Over the next three decades, Columbia and Yamhill saw moderate growth, with each reaching just under 50,000 by 1970. Washington, however, grew more sharply, reaching about 125,000 by the same year, thereby doubling its 1940 figures.
The population change in the US state of Oregon became even more pronounced by the year 2000. Columbia and Yamhill each experienced significant growth, with populations reaching approximately 90,000 and 80,000, respectively. Washington County, on the other hand, continued its dramatic increase, soaring to around 250,000, more than doubling its population since 1970 and demonstrating a far faster growth trajectory than Columbia and Yamhill. This data highlights the substantial variance in population growth trends among the three counties over the observed period.
Sample Answer 3
The line graph illustrates the population change in the US state of Oregon, comparing three counties—Columbia, Yamhill, and Washington—between 1940 and 2000.
Overall, Washington County experienced a substantial surge in population, particularly from 1970 onward, setting it apart from the more moderate growth seen in Columbia and Yamhill. By the year 2000, Washington's population had outpaced the other two counties by a significant margin.
In 1940, Columbia and Yamhill had modest populations, each close to 30,000 residents, whereas Washington stood out with around 75,000 people. Over the next three decades, Columbia and Yamhill both witnessed gradual increases, with each reaching nearly 50,000 by 1970. In contrast, Washington displayed a more pronounced rise, with its population almost doubling by this point, reaching approximately 125,000.
Between 1970 and 2000, the population change in the US state of Oregon’s counties became more distinct. Columbia and Yamhill continued to grow, reaching around 90,000 and 80,000 residents respectively by the end of the period. Meanwhile, Washington experienced an exponential increase, with its population soaring to about 250,000 in 2000, more than doubling the count of 1970. This trend underscores Washington County's considerably faster growth rate compared to the steady but slower increases in Columbia and Yamhill.
