The long-term trend toward lower-quality jobs in the United States continued between 2001 and 2004. Industrial job quality fell 1.6 percent nationally between 2001 and 2004. The decrease in occupational job quality was not quite as great at 0.9 percent. Thus, overall U.S. job quality dropped 2.5 percent during the three years, causing the U.S. average wage to be 2.5 percent less than it otherwise would have been. Arizona’s job quality fell between 2001 and 2004 at a pace worse than the national average. Relative to the national average, the industrial and occupational job mixes each slipped a bit more than 0.3 percent during the three years, for an overall decline of 0.7 percent. In Arizona, job quality in 2004 was 2.0 percent below the national average, but Arizona ranked 23rd among all states.

The best way to evaluate job quality would be to analyze a dataset that presents both occupational and industrial data, but the only dataset of this nature available by state comes from the decennial census. It is severely limited by small sample size, the latest data are for 1999, and the 1999 data are not consistent with the 1989 data. Thus, the initial work by the Seidman Institute on job quality ("Job Quality in Arizona", March 2005, presented data on Arizona job quality from several sources of either industrial or occupational data. "Job Quality in Arizona Compared to All States" is an extension of the March 2005 report. Arizona’s job quality in the latest year and its change over time is compared to the national average and is ranked among the 51 “states” (including the District of Columbia).

Arizona is one of the states in which the high-wage end of the employment distribution provides a more favorable impression of its job quality than that based on all employment. Thus, Arizona’s subpar job quality is not due to a scarcity of high-wage jobs, but instead results from lesser job quality in the remainder of the employment distribution. In particular, Arizona has an above-average share of very low-paying jobs that serve tourists and seasonal residents. In turn, the low overall average wage in Arizona — 7 percent less than the U.S. average — primarily results from factors other than job quality. The average wage in Arizona is less than the U.S. average in the vast majority of industries and occupations, both high- and low-paying.
