The Muslim community in the Netherlands is, for the most part, made up of migrants and their children. From the 1960s onwards, Turkish and Moroccan migrants took Islam with them to the Netherlands. Since that time, the number of Muslims has increased largely, partly due to further migration and subsequent family reunification. As a result, the Islamic faith in the Netherlands is strongly linked to migration history and is often practised within ethnic communities (Maliepaard & Gijsberts, 2012;Vermeulen, 2006). However, Islam is not just a migrant religion. Many Muslim migrants have passed on their faith to their children. For example, more than half This chapter is based on the report 'The religious experience of Muslims in the Netherlands' by the Netherlands Institute for Social Research (SCP) (Huijnk, 2018). It uses survey data to investigate developments among Muslim immigrants in the Netherlands over the period 2006-2015. The available data, which are based on various editions of the Dutch Survey of Integration of Migrants (SIM), are the most comparable databases over this period and enable us to provide an overview of developments in the religious experience and participation of different Muslim groups in the Netherlands. Most information exists on the two biggest Muslim groups in the Netherlands in particular, namely those with a Turkish and Moroccan background. We also briefly describe the religious experience of a number of smaller Muslim immigrant groups in the Netherlands (Afghan, Iranian, Iraqi, Somali and Surinamese Muslims). Together, these groups make up a large majority of the Muslim population in the Netherlands.
