Johan Junkka

I am a historian at Umeå University working on the study of demographic processes and social networks. In my PhD dissertation, I studied the role of social networks for the Swedish fertility transition, specifically that of voluntary associations and spatial communities.

Main research interests are in historical demography, topic analysis, digital history and R programming.
