This article investigates the development of rural migration in northern Sweden (1850–1950). During this period, northern Sweden experienced a slower rate of urbanisation than the rest of the country. This study proposes that decentralised industrialisation (i.e., rural-industrial labour, predominantly in the timber industry) introduced inertia to the urbanisation process by lowering the rate of rural-to-urban migration. Using longitudinal, individual-level data from the county of Västerbotten, the development of migration rates and migrant characteristics is explored via descriptive statistics. The rural population’s development and migration patterns closely correlate to the development of decentralised industrialisation. The results, therefore, indicate that decentralised industrialisation is a viable model for explaining the slow rate of urbanisation in northern Sweden.
