I believe this is the most current date available. It was a study conducted by the Manhattan Institute.

EXECUTIVE SUMMARY

The report's main findings are the following:

-The national graduation rate for the class of 1998 was 71%. For white students the rate was 78%, while it was 56% for African-American students and 54% for Latino students.
-Georgia had the lowest overall graduation rate in the nation with 54% of students graduating, followed by Nevada, Florida, and Washington, D.C.
-Iowa had the highest overall graduation rate with 93%, followed by North Dakota, Wisconsin, and Nebraska.
-Wisconsin had the lowest graduation rate among African-American students with 40%, followed by Minnesota, Georgia, and Tennessee. Georgia had the lowest graduation rate among Latino students with 32%, followed by Alabama, Tennessee, and North Carolina. Less than 50% of African-American students graduated in seven states and less than 50% of Latino students graduated in eight states for which data were available.
-The highest rate of graduation among African-American students was 71% in West Virginia, followed by Massachusetts, Arkansas, and New Jersey. The highest rate of graduation among Latino students was 82% in Montana, followed by Louisiana, Maryland, and Hawaii.
-Among the fifty largest school districts in the country, Cleveland City had the lowest overall graduation rate with 28%, followed by Memphis, Milwaukee, and Columbus.
-Fairfax County, VA had the highest overall graduation rate among the districts with 87%, followed by Montgomery County, MD, Albuquerque and Boston.
-Cleveland City had the lowest graduation rate among African-American students with 29%, followed by Milwaukee, Memphis, and Gwinnett County, Georgia. Cleveland City also had the lowest graduation rate among Latino students, followed by Georgia’s Dekalb, Gwinnett, and Cobb counties. Less than 50% of African-American students graduated in fifteen of forty-five districts for which there was sufficient data, and less than 50% of Latino students graduated in twenty-one of thirty-six districts for which there was sufficient data.
-The National Center for Education Statistics (NCES) finds a national high school completion rate of 86% for the class of 1998. The discrepancy between the NCES’ finding and this report’s finding of a 71% rate is largely caused by NCES’ counting of General Educational Development (GED) graduates and others with alternative credentials as high school graduates, and by its reliance on a methodology that is likely to undercount dropouts.
