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.

The war on poverty during the 1960s succeeded, cutting the national poverty rate in half by the early 1970s. Since then, however, the poverty rate of Americans under the age of 65 has increased. The poverty rate has climbed particularly among children; compared to an average of 15.5 percent during the 1971-to-1975 economic cycle, the poverty rate in each of the three cycles since 1982 averaged between 18 percent and 21 percent. One-in-five children lives in poverty and Arizona has consistently experienced higher poverty rates than the national average for all age groups except seniors.
