ABSTRACT
The impact of the Simpson-Rodino Law of 1986, which increased legal commuting labor migration across the Mexican-U.S. border, is examined using data from surveys undertaken in 1986 and 1990. "Using these data and LOGIT regression models which include variables related to individuals as well as their household members and their context, statistical evidence is generated in support of the propositions that, i) an expansion occurred of the spectrum of social strata incurring in this type of migration; ii) the selectivity characteristics of new entrants into this migration group show a reproduction strategy oriented toward upward mobility; and iii) contextual factors led to a geographic redistribution of the commuter migrant group in the state of Baja California."
