Nampa, the second-largest city in Idaho, was established in the late 1800s as a result of the completion of the Oregon Short Line railroad. Although the origins of the name Nampa are unknown, it is believed to be a Shoshoni Indian word meaning "moccasin," or "footprint." Once highly dependent on agricultural production, the city's economy has become more diverse and now also relies on manufacturing. Nampa boasts a mild climate, excellent parks and recreation, and proximity to Idaho's state capital, Boise. Northwest Nazarene University is located in Nampa, and the Snake River Stampede, one of the nation's top ten rodeos, is held every year in July. With nearly 50 percent population growth between 1990 and 2000, Nampa continues to thrive as it grows and diversifies.
