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.

Education decisions are among the most important choices people ever make. So we were surprised and disappointed to see an article so loosely reasoned and reckless in its conclusions as “Five Reasons to Skip College” published in Blank Slate at Forbes.com on April 18, 2006. The article never provides a numerical assessment of the costs and benefits of going to college, uses statistics inappropriately and in a way that biases the conclusions against college, contains conceptual errors on how to evaluate the return on a college education, and greatly exaggerates the only substantive criticism of typical evaluations of the financial worth of a college degree.

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.

The Phoenix metropolitan area is new by national standards, having developed primarily since World War II and particularly since 1970. However, settlement patterns were established in the 1800s, in part due to topographic features such as water courses and mountains. The war effort during World War II stimulated the growth of the Valley. After the war, a combination of events led to much faster growth. These included the desire of ex-servicemen stationed in the area during the war to return; improvements in air conditioning; charter government in Phoenix, which allowed a small pro-growth business group to gain power; and
aerospace and electronics firms siting facilities, in part because of the federal government’s designation of Fort Huachuca as the principal proving ground for electronic defense equipment. The modern period began around 1970, when a maturing metro area coincided with the baby-boom generation reaching adulthood. The result was even more rapid growth that has continued to the current time. Rapid growth of the Phoenix metro area is expected to continue for at least the next 50 years. Land and water availability should not restrict growth until after the current population of nearly three million exceeds seven million in 2050.

The determination of the number of businesses operating in Arizona is not a straightforward proposition due to data deficiencies and definitional issues. The best data — from the U.S. Census Bureau — are more than two years old. The Census Bureau data are divided into two series: businesses with employees and nonemployer businesses. Each series is based on administrative records. While neither series is affected by sampling error, both are subject to nonsampling error. Certain industries are excluded from each series.
