      abstract = {This report updates a 1979 classification system of  nonmetropolitan (nonmetro) counties developed by the  Economic Research Service that identified rural counties  according to their economic and social structure. The  update to 1986 provides a base for effectively planning  rural development. The report reveals that between 1979 and  1986 the number of farming, manufacturing, and mining  counties dropped steeply, while the number of specialized  government counties and unclassified counties grew.},
