The number of Catholics is not only declining, but many people who identify themselves as Roman Catholics also do not regularly attend Sunday Mass. 172,000 people, or 1% of the Dutch population, attend Mass on any given Sunday according to information by the Catholic Institute for Ecclesiastical Statistics (KASKI) in their 2010 statistical update of the Dutch Catholic Church. Most Catholics live in the southern provinces of North Brabant and Limburg, where they comprise a majority of the population in the diocese of Roermond in the province of Limburg, based on self-reported information by the Catholic Church.
