Composition and response of the LISS panel
About 80% of the eligible persons living in the registered panel households participate in the panel . The monthly response of these participants varies between about 50% and 80%, depending on the questionnaire and month. Between October 2007 and February 2010 the monthly response gradually decreased. From March 2010 onwards, it slightly increased again, as a result of special efforts to contact inactive panel members.
A study of the respresentativeness of the LISS panel in the first year after its recruitment showed that some specific groups, for example elderly women and non-western first generation immigrants, were initially somewhat underrepresented in the LISS panel . A more recent study compares the composition of the LISS panel between April 2008 and April 2010 with the Dutch population .
Since the start of the panel about 18% of the households that ever participated have left the panel. Descriptions of which specific demographic groups have especially high or low probabilities to become inactive or to drop out are given by De Vos [5,6].

Composition and response of the immigrant panel
The panel members of the immigrant panel have been completing questionnaires since October 2010. Three non-Western groups are for the moment somewhat underrepresented in this strand.
