Young African American college graduates say they are more responsibly committed to reaching financial goals than previous generations, according to a study released Tuesday by Northwestern Mutual Life Insurance. Seventy percent of African Americans age 18 to 34 said they were either “disciplined” or “highly disciplined” when it came to finances, compared to just 47 percent of those 35 and older. However, 40 percent of those 55 and older reported having financially prepared to live to age 95, as opposed to just nine percent for the 18 to 34 set.
