By 1993, more than 1 out of 4 adults, 18 years old and over (27 percent), had obtained a degree of some type beyond high school, a substantial increase over the 21 percent reported in 1984. The proportion of the adult population without a high school diploma decreased to less than 1 in 5 (19 percent in 1993 and 26 percent in 1984).

 More than one-half of the adult population reported a high school diploma as their highest degree in 1993 (54 percent). Of these, slightly more than one-third had also attended, but had not received a degree from a post-secondary institution.
