The purpose of this study is to build an econometric and demographic model of the Sun Corridor to forecast long-term economic and demographic conditions in the “megapolitan” region. To this end, the study examines the long-term economic and demographic forces that could affect economic development in the 3-county Sun Corridor megapolitan area that includes Maricopa, Pinal and Pima Counties. This information is used to develop a set of realistic economic/demographic scenarios to drive the forecasting model.

This report is one of several from Statistical Research Inc. written to develop the Cultural and Historic Resources Element of the Sonoran Desert Conservation Plan. Divided into four parts, the report summarizes available information that reflects the experience of (1) ancient peoples of Southern Arizona; (2) indigenous peoples; (3) non-indigenous peoples of the historical period; and (4) Pima County today.

These species include not only the common one that we live with on a day to day basis, but also some of the rare species that most of us are not lucky enough to see (but still care about preserving).
