Over the past two decades, educational attainment and college enrollment have increased substantially among Hispanics, the nation’s largest minority group, and blacks. For example, the
high school dropout rates among Hispanics and blacks ages 18 to 24 reached record lows in 2014: just 12% for Hispanics and 7% for blacks, down from 33% and 16%, respectively, in 1993.
College enrollment has grown among all races and ethnicities since 1993, but gains have been biggest among Hispanics. In October 2014, 2.3 million Hispanics ages 18 to 24 were enrolled in either a two- or four-year college – up from 728,000 in 1993. Among blacks in the same age group, 1.5 million were enrolled in college in 2014 – up from 897,000 in 1993.
