The pieces you see in this e-book provide rich data from the lives of migrant children and sometimes their families. Chantal Tetreault’s piece among transnational Algerian teen girls in Paris and Kendall King’s study in Ecuador are linguistic in focus, bringing up the ways that performance in language is part of the practice of immigrant experience (Tetreault) and highlighting how regard for globalization and attention to language are deeply intertwined for immigrant communities (King). Most of the pieces provide in depth points of view from child migrant perspectives—data that is often difficult to obtain and portray sensitively. Child-centered data is exceptionally valuable in helping us to grasp the micro-forces by which childhood is changing through migration and how children experience or activate agency under trying conditions. Laure Bjawi-Levine among Palestinians in Jordan, Lauren Heidbrink among Spanish speakers in immigration detention in the U.S., and Jill White among Mexican children in U.S. labor and schooling environments demonstrate ways in which children’s self-understanding is constrained by state and economy in ways that determine a marked life course. Kanwal Mand’s also deeply child-centered analysis shows us how migrant childhoods can be notably shaped and sometimes constrained largely by urban housing and schooling environments, in this case for Pakistani second-generation children in London. Cati Coe’s interviews with informants in Ghana, and Catríona Ní Laoire’s study on return Irish migrants examine strains across the generations that affect the emotional management of families and individuals to handle the spatial and temporal challenges of migration. And finally, Michelle Moran-Taylor provides a rich analysis of the gendered and socioeconomic strategies that families use to negotiate the challenge of child-rearing in the home area when families are geographically separated, drawing especially on data from Guatemala.
