Union members made up 4.7 percent of employed workers in Idaho last year, among the lowest rates in the country, according to a new report from the Bureau of Labor Statistics.
The total number of union workers in Idaho was 29,000 last year, the BLS said. Another 7,000 were represented by a union in some way but weren't members themselves.
Idaho's 2013 membership rate was less than half the peak of 10.2 percent in 1993, the bureau said. The U.S. rate was 15.7 percent that year, according to BLS data.
The national rate of union membership among wage-and-salary workers in 2013 was 11.3 percent, unchanged from the previous year.
But Idaho's union membership has been below the U.S. average for as long as the BLS has kept track since 1989.
Idaho was in good company. Nine states had union membership rates below 5 percent last year, with North Carolina at the lowest rate of 3 percent.
