The available studies and opinion polls are examined for indications of the degree and the content of political knowledge of the Belgian citizens. Political knowledge differs strikingly depending on the components of decision making: political parties, office bolders and their competence, power relations, institutional settings, pressure groups, corporatism and policy measures. Proceeding from personification to content and from more important to less important aspects, the knowledge declines noticeably. A marked portion of the populationshows a lack of even the most elementary knowledge.
