ABSTRACT
This chapter describes the selection of the research setting, organization of the requisite data items and the organization conversion into measures of the family and community-level variables. Families with insufficient cash income are expected to adopt a migration-for-survival strategy, while those with expected insufficient future income are expected to adopt a migration-for-mobility strategy. Families who own or have secure tenancy arrangements for farmland are expected to be less mobile, but only if they obtain sufficient income from their farm activities Commercialization of agriculture is expected to increase migration where the current technology shifts labor demand either downward or to a pattern that no longer balances the pattern of labor supplied by the family members or by other community residents. Standard approaches to measurement of economic development have relied on such measures as per capita income or gross national product.
