The aim of the chapter is to establish how widespread negative attitudes towards Jews and Muslims are among the Norwegian population, and to look for factors that may stimulate such attitudes, through an analysis of the two representative population surveys conducted by The Norwegian Center for Holocaust and Minority Studies in 2011 and 2017. Attitudes towards Jews are measured by indices of prejudice, dislike, social distance, and a summary index of antisemitism. Islamophobia is measured by a corresponding set of indices in 2017. The level of negative attitudes towards Jews is low and declining for all indices. Negative attitudes towards Muslims are more widespread. Women, younger people and those with higher education have a lower level of negative attitudes towards the two minorities. Opinion on the Middle East conflict affects antisemitism and Islamophobia in opposite directions, while both are strongly influenced by xenophobia. Negative attitudes towards the two minorities tend to coexist in individuals.
