Due to the diversity among rural areas, programs tailored to particular types of rural communities may be more effective than generalized programs. Bender et al. (1985) described seven different types of rural communities differentiated by economic base, population characteristics, and the presence of Federally-owned land. These communities include: those primarily dependent on farming, manufacturing, or mining; those specializing in government functions; those in persistent poverty; those composed mainly of Federal land; and those whose population includes large numbers of retirees. Even rural communities with similar population numbers, densities, and the like, vary tremendously because of the variety of subcultures they contain.
