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.)

Northern Idaho Counties, 1990
Idaho's ten northern countes are the most dependent upon the forest products
industry. In 1990, roughly 60 percent of all forest labor income earned
in Idaho was earned in the northern counties.
