This chart shows the number of students from different income levels and how many of them dropped out school between the years 1972 and 2008. As you can see from the chart above since 1972 for all the levels of income rates have dropped. For low income families the rate got as high as 17% in 1973. In that same year middle income was at 6% and high income kids were at 2%. The huge gap between the two income levels shows that there is some relationship between low levels of income and high school dropout
