Underemployment is another indicator of nonmetropolitan labor's disadvantaged circumstances. Yearly employment transitions during 1968 and 1993, show that compared to urban counterparts, adequately employed nonmetro workers were more likely to become underemployed; the nonmetro underemployed were less likely to become adequately employed; and nonmetro women and minority groups were more disadvantaged. Statistical controls strengthened the metro advantage. Contains 37 references. (Author/SV)
