In 2006, CentERdata received major NWO funding for the project: an advanced multi-disciplinary facility for Measurement and Experimentation in the Social Sciences (MESS). This NWO subsidy was instituted by the Cabinet with a view to boosting the Dutch knowledge economy and the climate for innovation in our country. These funds have been used to establish a new online panel of 5,000 Dutch households: the LISS panel (Longitudinal Internet Studies for the Social sciences). The panel is the core component of the MESS project and is based on a true probability sample of households. Since October 2010, the MESS project includes a new immigrant panel in addition to the regular LISS panel.
