Abstract It is postulated that water resource needs are importantly affected by both size and composition of population dispersion, and that migration patterns are the major sources of uncertainity in predicting population change. A predictive model for migration behavior was studied. Using principally multiple regression analysis on migration across state economic area boundaries in the form of out-migration rates for 1949-50, it is concluded that migration rates are a dynamic phenomonon dependent primarily on accessibility (transportation, communication, information, distance) and available opportunity (employment rates, income, amenities). However where accessibility is low (e.g., poor communication, great distance) out-migration is not significantly affected by differential opportunity. A strong case is made for better statistical data.
Highlights Notes Is concerned with the ecological determinants of outmigration and the influence of community organization on the outmigration rates of community populations.
