Attainment of a high school diploma or its equivalent is an indicator that a person has acquired the basic reading, writing, and mathematics skills needed to function in modern society. The percentage of young adults ages 18–24 with a high school diploma or an equivalent credential is a measure of the extent to which young adults have completed a basic prerequisite for many entry-level jobs and for higher education.
NOTE: Percentages are based only on those not currently enrolled in high school or a lower education level. Prior to 1992, high school completion was measured by the completion of 4 or more years of high school rather than the actual attainment of a high school diploma or equivalent. For data before 2003, the 1977 Office of Management and Budget (OMB) standards for data on race and ethnicity were used to classify persons into one of the following four racial groups: White, Black, American Indian or Alaskan Native, or Asian or Pacific Islander.
The revised 1997 OMB standards were used for data for 2003 and later years. Under these standards, persons could select one or more of five racial groups: White, Black or African American, American Indian or Alaska Native, Asian, or Native Hawaiian or Other Pacific Islander. Those reporting more than one race were classified as "Two or more races." For 2003 and after, when separate reporting was possible, respondents who reported being Asian or Native Hawaiian or Other Pacific Islander were combined for continuity purposes. Also, beginning in 2003, those in a given racial category represent those reporting only that race. Data from 2003 onward are not directly comparable with data from earlier years. Data on race and Hispanic origin are collected separately. Persons of Hispanic origin may be of any race.
