Researchers at SOFI collect their own data, which are stored at the institute and eventually deposited with the Swedish National Data Service (SND). SOFI has a policy of making collected data available to the research community within a reasonable time after collection.

The Social Policy Indicators (SPIN) database provides a foundation for comparative and longitudinal research on the causes and consequences of welfare states.

SPIN provides comparable data on citizens’ social rights and obligations. The database focuses on analysing institutions and how they are reflected in social policy legislation.

Data are collected in a consistent and methodologically standardised manner to facilitate quantitative research on social policy over time and across countries. SPIN currently covers 36 countries, several of which have data on major social policy programmes from 1930 to 2019..
