In, 2008 Le Centre d'Etude de la Vie Politique (CEVIPOL) published a study using exit polling data following the 2007 Belgian federal election. The study found that among Muslims in Brussels, 42.3% voted for the Socialist Party, 16.7% for the Humanist Democratic Centre, 14.7% for the Reformist Movement and 12.2% for Ecolo. The study also concluded that religiosity among Muslims did not have "a strong impact on their voting behaviour." In addition, the variable related to religious belonging or practice was not enough to explain the vote of the Muslim electorate. Other determining factors related to an often relatively low socioprofessional status, age (more than half of the Muslims interviewed were under age 34) and level of education (lower than the average of the other groups) were more integral to the firm attachment to the political left.
