This article investigates the historical development and transformation of Swedish integration policy, including its predecessor immigrant policy, as a “biopolitics of the population”. “Biopolitics of the population” refers in this article to all governmental interventions targeting the population, or parts of it, with a view to producing a collective body of a particular quality and identity. Swedish integration policy is thus analyzed in order to answer questions such as: how has the population been embodied over time? How has the Swedish grammar of multiplicity and fragmentation changed? Which groups within the population have been considered to be in need of incorporation? Why has the attachment of these groups to the collective body been seen as precarious and/or questionable?
