Last year, 53 percent of the Dutch considered themselves to be religious, according to figures published Thursday by the Dutch national statistics office CBS.
One in four people consider themselves to be Catholics, 32 percent are protestants in the Netherlands and 5 percent are Muslims.
Half of the orthodox Protestant groups say they go to church at least once a week. Almost 27 percent of Muslims say they go to a mosque once a week, but just 6.3 percent of Catholics say they go to a church.
Muslims account for the largest religious population in The Hague (14 percent) and in Amsterdam (11 percent), CBS noted.
The Netherlands has a total population of about 17 million.
