Abstract:  Between 1985-90, metropolitan Los Angeles received about 400,000 working immigrants and about 575,000 working native in-migrants.  We subdivide these native- and foreign-born migrants by national origin and ethnicity to examine the processes that channel recent arrivals into different industrial sectors.  Our analysis extends previous research on migrant employment and the ethnic division of labor in two ways.  We compare the employment of recent arrivals to residents for several groups across a large, diverse, regional economy.  We also consider the role educational qualifications play in the allocation of different migrant groups to jobs at this aggregate analytical scale.  The results show that both native- and foreign-born groups channel into particular industrial sectors.  The strength of group channeling, however, varies by national origin and ethnic group.  Native-born in-migrants are more likely to channel into the industries where their co-ethnic residents work than immigrant newcomers.  We also find some groups more likely to take jobs based on their educational qualifications (whites, blacks, Filipinos and Chinese), whereas ethnic group effects dominate the choice of industry of others (Koreans).  The analysis investigates the issue of inter-ethnic labor market competition by comparing the employment profiles of newcomers with those of resident ethnic groups.  It shows that immigrants experience more inter-ethnic labor market competition from newcomers than do native whites and blacks.
