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).
