Only 29.4 percent of the Navajo Nation’s income is spent on the reservation. This means that opportunities abound to serve the Navajo consumer as well as the visitor. Service development through the Navajo Nation’s Shopping Center enterprise has built nine shopping centers throughout the reservation, which has encouraged the growth of such businesses as Laundromats, theaters, supermarkets, fast food franchises, hardware retail stores and gas stations. Among the services available to the developer are over 100 Navajo-owned contracting firms for construction, and sub-contractors and suppliers for renovation of commercial and industrial properties
