“…According to central place theory, the costs associated with providing higher-order services (appliances, motor vehicles, major trauma intervention) are higher than those associated with lower-order services (groceries, sporting goods, nursing care), thus they require a larger population to support them (Mulligan, 1984). Factors other than urban population size affect service availability and well-being in rural areas, including rural population density, industrial structure, and natural amenity features (Isserman, Feser, & Warren, 2009;McGranahan, Wojan, & Lambert, 2010;Vias, Mulligan, & Molin, 2002). However, recent studies confirm that the variability of rural well-being is still very strongly tied to the structure of the urban hierarchy -places near large cities have lower poverty rates, higher incomes, more jobs, higher population growth, and better access to retail services compared with more remote areas (Partridge, Rickman, Ali, & Olfert, 2008a, 2009aPorter & Howell, 2009).…”
