An important part of the work at SOFI is the collection of data of various kinds. Some of Sweden's most valuable data materials have been prepared at SOFI. A stated policy on SOFI's part is to make materials available to the research community within a reasonable time after the collection. The data materials are therefore eventually deposited at the Swedish National Data Service (SND).

The Social Policy Indicators (SPIN) database provides the foundations for new comparative and longitudinal research on causes and consequences of welfare states. SPIN makes available comparative data on social rights and duties of citizens, oriented towards analyses of institutions as manifested in social policy legislation.
