The Houston-Galveston Economic Project was a part of an overall Texas project designed to construct input-output models for nine economic regions defined for the State of Texas and an aggregate model for the State. The Houston-Galveston Region is defined as a 26 counties area including the Houston and Galveston SMSA's and 19 surrounding counties to the north and west of the metropolitan areas. The model has 159 sectors, 151 intermediate and 8 final demand or primary payments sectors. Intermediate sectors are defined in terms of one or more three or four-digit Standard Industrial Classification industries. The data used to estimate the technical coefficients and the final demand components of the transactions matrix were collected by field surveys of a sample of business establishments in the Region, information in State Government offices and secondary source materials. Field survey data represents the primary source for all sectors except agricultural, selected service and government sectors.
