Qualitative and quantitative procedures have been used to aggregate communities and counties for regional economic analysis. However, Once aggregated, communities and counties are perceived as homogeneous entities; this often belies the diversity that may exist. In order to capture the non-uniqueness of counties, fuzzy-set clustering procedures were employed to derive a typology of Nevada counties. Fuzzy-set clustering procedures employing fuzzy-set membership values and possibility theory derive county membership values associated for specific county clusters. Information from fuzzy partitions yields a means for posterior evaluation of county clusters which is independent of the algorithm producing them. From county membership values calculated from results of the fuzzy-set clustering analysis for Nevada, specific economic development programs for aggregate and individual counties are derived.
