The line graph compares the population change from 1940 to 2000 in the three different countries in the U.S.state.

Looking at the line graph, it is immediately obvious that the people who lived in Washington was largest and the figure for Columbia was lessest between 1940 to 2000.

In 1940, the first year on the graph, the number of people who lived in Washington was highest, at 75 millions, while the figure for Yamhill was significantly lower, at 30 millions, compared to 25 m for Columbia.

In 1970, the amount of population to Washington increased sharply about 125 millions. In addition, there was also changed of population in Yamhill and Columbia but this had slight, changing less than 20 millions.

Thirty years later, the population continued to rose. Interestingly enough, in washington, the population lifted suddenly and reach a peak of around 240 millions. Meanwhile, the number of people who lived Yamhill increased

at 90m, compared to 75m for Columbia.
