Electrification and the Oregon Trunk Railway reached Redmond in 1911. The rail link opened markets for farmers and merchants. By 1930, the town had grown to 1,000 and by 1940 had nearly doubled. In the 1940s, Redmond was a U.S. Army Air base and commercial air service was established at Roberts Field after World War II. In the 1950s, 60s, 70s, and most of the 80s, the population remained relatively static, growing slowly around a small commercial/retail center and manufacturing industry. However, during the 1990s, the population began to grow along with most of Deschutes County. Between 2000 and 2006, Redmond's population grew 74.3%, making it among Oregon's fastest-growing cities each year. This growth continued through 2006, increasing the population to 23,500. Its growth is fueled by employment and a lower cost of living.
