The purpose of this report is to provide a description and analysis of a regional economy within the state of Colorado. The study region consists of two counties in south west Colorado, La Plata and Montezuma counties. The two-county region's 1980 population is estimated at 43,934 inhabitants with an income of $250 million. On balance, the region is a net exporter. The model used to analyze their economy can not only describe the economic interdependence existing between sectors of the economy, but also has the capacity to demonstrate, sector by sector, the total socio- economic consequences of any number of development scenarios. The input-output model is thus both descriptive and analytical.
