Federal education officials say Mississippi has a high school graduation rate of 75%. Alabama has a graduation rate of 72%.
Here's a comparison to neighboring states:
The U.S. Department of Education released the data this week.
It details four-year high school graduation rates in 2010-11, the first year for which all states used a common, rigorous measure.
Federal officials say varying methods of graduation rates that states used previously were unreliable for state-by-state comparisons.
However, education officials said in a statement that the new data allows for such comparisons and can be used by states, districts and schools to promote greater accountability and increase graduation rates.
