Building on T.H. Marshall’s ideas about social citizenship, SPIN makes available comparative data on social rights and duties of citizens, thereby moving research beyond analyses of welfare state expenditures. The SPIN database is oriented towards analyses of institutions as manifested in social policy legislation. Data are carefully collected in a coherent and consistent methodological manner to facilitate quantitative research of social policy across time and space. To date, SPIN covers 36 countries, of which several have data on core social policy programs from 1930 to 2019.

SPIN is an active partner of the Comparative Policy Laboratory (COMPLAB), which is a datainfastructure run in collaboration between Stockholm University and Uppsala University. Besides data on social policy, COMPLAB also services the research community with comparative and longitudinal data on environmental policy and migration policy. COMPLAB is part of larger national infrastructure on Democracy, Environment, Migration, Social policy, Conflict, and Representation (DEMSCORE), hosted by the University of Gothenburg (www.demscore.se)
