high school and the percentage of those having earned
Bachelor's degrees remained at an all-time high, while the growth in both categories has slowed down over the past two decades. The vast majority of the population, 85.2%, had finished high school and
over a quarter, 27.7%, had earned a Bachelor's degree. The percentage of both college and high school graduates continued to increase since 2000. Since 1983 the percentage of people graduating from high school has increased from 85% to 88%. The greatest increases in educational attainment were do ented in the 1950s, 60s and 70s. In the 1950s and much of the 1960s high school graduates cons uted about 50% of those considered adults (25 and above). The young adults aged between 25 and 29, percentage of high school graduates was roughly 50% in 1950 versus 90% today.
