The median years of school completed by the Negro population 25 to 34 years old was 11.3, or years more than the 8.3 years for Negroes 45 to 54 years old. Corresponding medians for white persons were 12.5 and 12.0 years, respectively. These findings are based on national sample statistics collected by the Bureau of the Census in the March 1964 Current Population Survey.
