SCP draws data from a large number of surveys of the Dutch population, and sometimes also of the populations of other countries.
The most important supplier of data is Statistics Netherlands (CBS), though another key data provider is DANS (Data Archiving and Networked Services). Other sources of data include government departments, universities, etc.
SCP has also carried out surveys itself in a number of areas, either alone or in partnership with other research institutes. Topics are time use, cultural changes, the social position of ethnic minorities, the life situation of older persons living in senior housing facilities, and the life of school pupils.
