A graph shows income on the horizontal axis and percentage voting on the vertical axis. 48% of voters earn less than 10,000 dollars. 55% earn between 15,000 and 19,999 dollars. 62% earn between 30,000 and 39,999 dollars. 71% earn between 50,000 and 74,999 dollars. 78% earn between 100,000 and 149,999. Look at the bar graph, which shows voter turnout in one election year. Which is the best conclusion someone can draw from this graph? All income groups vote at roughly the same percentage. The less one earns, the less likely one is to vote. Middle-income people vote at higher rates than other Americans. Income has very little to do with voter turnout.
