Social mobility among migrants between Mexico and the U.S. and within the U.S. labor market

This paper uses data collected in 4 Mexican communities (2 rural and 2 urban) in 1982 and 1983, using a sample of 200 households, plus an additional 25 households. This analysis supports these hypotheses: 1) a U-shaped pattern of occupational mobility exists among migrants to the US; 2) the reversal of the initial downward mobility is positively correlated with the accumulation of experience within the US; and 3) the relative steepness of both legs of the pattern vary across socioeconomic with rural origin, illegal, and poorly educated migrants experiencing the slowest reversal of fortune. The occupational mobility of Mexican migrants to the US has 2 distinct phases: 1) labor market entry and 2) that which occurs within the US labor market. Both phases are characterized by occupational immobility and by migrants' area of origin. Other important findings are 1) the slowness with which upward mobility occurs among migrants on their 1st trip, 2) the dominance of agriculture as an occupational group, and 3) an improvement in mobility prospects with increased US experience for repeat migrants. Immobility for 1st time entrants pervades all occupational categories and is exceptionally high for rural origin migrants in agriculture. Rural origin unskilled workers encounter greater mobility constraints, indicating a rural agricultural worker may accomplish an upward movement to the unskilled category, but the chances of further movement are remote. Upon entering the US, the probability of being employed in agriculture is over 25% for all groups except the unskilled. Adjusting successfully to US society is best accomplished by migrants whose Mexican occupation is professional, technical, skilled, or service or who have carefully timed their migration and have accumulated significant experience in the host society. It is only with exposure to the US society, either through a prolonged stay or many trips, that a migrant can overcome the debilitating effects of a disadvantaged socioeconomic background.
