b'E C O N O M YMost of Bannock Countys commercial and industrial development is in Chubbuck and Pocatello. Since its inception and over time, the countys economy has been driven by railroads, farming and ranching, mining, heavy industry, and Idaho State University (ISU). However, the economic sectors are shifting somewhat from traditional heavy industries to new clean industries. Fort Hall Indian Reservation and the cities are attracting more of these industries (such as Hoku), in part because of ISU and because of other natural and cultural amenities. Bannock County does not play a primary role in business recruitment or retention, but has focused on partnerships with cities and the Bannock Development Corporation (BDC), which has a business recruitment mission to expand economic development.5Top Five EmployersIdaho State University3,600 employeesPortneuf Medical Center1,900 employeesSchool District #251,600 employeesON Semiconductor710 employeesCity of Pocatello700 employeesMajor Fertilizer/Chemical CompanyJ.R.
