An interindustry or input‐output model represents the structural interdependence of a national or regional economy. The inverse matrix of such a model reveals in each entry the amount of a given commodity necessary for the delivery of a unit of output of product to final demand. Usually, such entries are in dollar terms; however, these values can be converted to factor requirements such as man‐years of labor or acre‐feet of water. Such matrices are then termed ‘factor content’ matrices. Some of the specific uses of a ‘water content’ matrix constructed from a western states multiregional input‐ouput model and a vector of water use coefficients are discussed. Suggestions are made concerning improvement of the present water use data and the applicability of these data to regional water planning.
