Miles Driven and Population Growth in Massachusetts

The line graph contains two lines; one for Miles Driven in Massachusetts, and one for Population in Massachusetts. The vertical axis shows the percent increase since 1970 for both of these indicators. The population line has a shallow slope, increasing slowly and steadily from zero percent growth to about 10% growth in 1000 and a forecasted 20% growth in 20020. The Miles Driven line, however, has increased much faster, showing a steeper line slope. In 2000, the increase for Miles Driven is over 70% and in 2020 it is predicted to be over 100%.
