The data displays the population of the Netherlands by religion in 2015. The data displays that in 2015 half of the Dutch population did not identify with any religious denomination. Of the religious population, the biggest number of people (nearly 25%) identified themselves as Roman Catholics. That is particularly interesting, as the dominating church in the Netherlands since the Reformation had been the Protestant church. According to the source, approx. 15% of the Dutch population considered themselves a member of the three main protestant churches, the Dutch Reformed Church, the Protestant Church in the Netherlands and the Reformed Churches in the Netherlands.
