Relative to the size of the state economy, Idaho has one of the largest forest products industries in the nation. Using percentage of total labor income as a measure of relative dependence on the forest products industry, Idaho ranks third among all 50 states. Between 1987 and 1991, roughly six percent of Idaho's total labor income was earned in the forest products sector.
(The highest percentage - nine percent - was earned in Maine.)
