The Stockholm Population Project
Summary
In this project, we collect and analyze unique data by combining population and tax registries, we capture detailed information on all individuals residing in Stockholm during the mid-20th century. These registries provide insights into individuals’ residences, households, incomes, rents, occupations, and workplaces, allowing us to construct a linked employer-employee panel dataset.
Principal investigator: Martin Önnerfors

Our focus is on examining the decline of inequality and the role of local labor markets in this process. With the employer-employee linked data, we can estimate both between- and within-firm income variation. Additionally, we explore how the tight labor market in the post-World War II era influenced wages and the distribution of income. Using Stockholm as a case study, we also investigate the impact of the expansion of public transportation on local labor markets and assess how this affected income distribution.
