The educational attainment in 2000 of the entire 25-or-older population in Arizona was similar to the national average and ranked in the middle of the states. Arizona compared less favorably to two sets of comparison states: “competitor” states defined by the Greater Phoenix Chamber of Commerce and “new economy” states identified by the Milken Institute. In 1990, however, Arizona’s educational attainment had exceeded the national average. Arizona ranked among the bottom 10 states in the 1990 to 2000 gain in educational attainment. Among both the entire population and those active in the labor force in 2000, the
educational attainment of Arizona residents 55 or older exceeded that of their peers nationally.

Available data on the cost of living indicate that living costs in Arizona are close to the national average — thus, the state’s lower-than-average wages are not offset by low living costs. No productivity data exist for Arizona. Worker productivity in Arizona could be below the national average due to lesser investments in physical or human capital, which would result in lower wages. Labor market supply and demand factors are a likely cause of the low wages in Arizona. A substantial number of people seem willing to move to Arizona and accept a substandard wage in exchange for perceived qualitative advantages to living in Arizona, primarily climate.
