Group Ties amid Industrial Change

Abstract

Abstract Coethnics often work in the same industries. How does this ethnic clustering affect individuals’ political loyalties amid industrial growth and decline? Focusing on migrant groups, the author contends that ethnic groups’ distribution across industries alters the political allegiances of their members. When a group is concentrated in a growing industry, economic optimism and resources flow between coethnics, bolstering migrants’ confidence in their economic security and dissuading investments in local political incorporation. When a group is concentrated in a declining industry, these gains dissipate, leading migrants to integrate into out-groups with greater access to political rents. Analyses of immigrants near US coal mines in the early twentieth century support this theory. The article shows how ethnic groups’ distribution across industries shapes the evolution of group cleavages and illuminates how decarbonizing transitions away from fossil fuels may reshape identity conflicts.
