This article seeks to understand civic participation among Asians and Latinos in a multiethnic, multiracial context. We investigate the usefulness of an expanded model of civic engagement, one that makes central factors related to migration, such as length of residence, language acquisition, and citizenship, for groups that include a large number of immigrants. The 1992–1994 Los Angeles Survey of Urban Inequality allows us to test a model of civic participation that incorporates variables previously neglected – migration-related factors, but also multiracial contexts and interracial ties – to better explain participation differences among a diverse population.
