After 1970, the emphasis on Catholic concepts and traditions such as hell, the Devil, sin, Confession, kneeling, catechesis, having the Host placed on the tongue by the priest, and the doctrine about widows' remarrying, divorce, and premarital sex rapidly disappeared; these concepts and traditions are rarely, if ever, found in modern Dutch Catholicism. A cultural divide is still found between the "Catholic" south and the "Protestant" north, but with a total of 1.5 million people and 20% of the industrial production in the Netherlands, the southern "Catholic" area BrabantStad has become one of the major economically important, metropolitan regions of the Netherlands.
