what percentage of the us has a high school diploma
Educational attainment in the United States Since 1983 the percentage of people either graduating from high school or failing to complete high school but getting a GED certification has increased from 85% to 88%. The greatest increases in educational attainment were documented in the 1950s, 60s and 70s. In the 1950s and much of the 1960s high school graduates constituted about 50% of those considered adults (25 and above). For young adults aged between 25 and 29, the percentage of either high school graduates or GED obtainers was roughly 50% in 1950 versus 90% today.[2]
