title: A partial hierarchical regionalization of 3,140 US counties on the basis of 1965-1970 intercounty migration.
abstract: "Because of a special tabulation recently completed by the US Bureau of the Census for the 1965-1970 period, interareal migration flows--for the first time--can be examined on the level of the 3,140 counties.... Preliminary results, restricted to six (of a theoretically possible 3,139) levels, are discussed here.  They provide some indications of the full results, as well as an upper bound (40,000) on the number of largest doubly standardized values it is necessary to consider in the full clustering."
