Logging of lumber and other wood industries have been historically prevalent in this heavily wooded area. By late nineteenth century, the mill town was home to several lumber, pulp and paper mills, including the Riverside Mill, Forest Fibre Company and White Mountain Pulp & Paper Company. Recent economic development has been based on the correctional industry, with the 750 bed Northern New Hampshire Correctional Facility built in 1999 and employing approximately 200 people. The Federal Bureau of Prisons plans on opening a 1200 bed medium security facility which will employ approximately 350 people.
