Introduction
Aided by a diverse Advisory Committee, we have carried out an in-depth, exploratory study in two cities which reflect the varied experience with immigration across the country: Denver, Colorado, where we focus on Mexican immigrants and Portland, Maine, where we focus on three of the many refugee populations which have settled here: Cambodian, Somalian and Sudanese children and families. We believe that the contrasts, not only in the immigrant populations themselves, but also in the political and historical contexts of the communities in which they live, offer us an opportunity to enrich the field of research on child care choices for this vulnerable population of children and families.
