Summary of Findings In 1992, 179.0 thousand persons were employed in Arizona's manufacturing establishments. This figure represented a decrease of 3 percent from the 1987 figure of 184.1 thousand workers. The total value added by manufacture for the State amounted to $15.0 billion in 1992. This figure, along with all dollar figures in this report, are at prices current for the year specified and, therefore, are unadjusted for changes in price levels. Consequently, when making comparisons to prior years, users should take into consideration the inflation that has occurred. In the State, the leading industry groups ranked by employment were electronic and other electric equipment, transportation equipment, printing and publishing, and instruments and related products. They accounted for approximately 51 percent of the State's 1992 employment. This represents a shift from 1987 when electronic and other electric equipment, transportation equipment, industrial machinery and equipment, and instruments and related products accounted for approximately 55 percent of the State's employment. The leading counties in the State ranked by employment were Maricopa, Pima, Pinal, and Mohave. They accounted for approximately 93 percent of the State's 1992 manufacturing employment. These same counties were the leaders in 1987 when they accounted for approximately 93 percent of the State's employment. Single-establishment companies with up to 20 employees (cutoff varied by industry) were excluded from the mail portion of the census. The data for these establishments (and a small number of larger establishments whose reports were not received at the time the data were tabulated) were obtained from administrative records of other agencies or developed from industry averages. For this State, these establishments accounted for 7 percent of the total value of shipments.
