A 1987 study that examined the economic performance of 23,500 graduates in 1983 of 14 vocational programs in Ohio used federal income tax records. Twelve of the programs with 21,857 graduates were at the secondary level, and 2 with 1,643 graduates were at the associate level. The incomes of vocational graduates were compared to income of equivalent groups in the general population. The study also investigated the geographic mobility of vocational graduates since 1979. Results showed predominantly higher incomes for vocational graduates than for the general population. The result varied by vocational program, but the ratios were higher than 1 for the 1979 graduates in all programs. The income advantage ranged from 10 to 79 percent for graduates of secondary programs and from 11 to 68 percent for graduates of associate programs.
