Many people think that the Netherlands was predominantly Protestant or Dutch Reformed, and that Catholics were a minority. While that may have been true for the country as a whole, there are several areas where almost everyone was Catholic.
Areas that are predominantly Catholic include:
- Some parts of Overijssel (area around Oldenzaal)
- Some parts of Gelderland (area around Groenlo, area around Arnhem and Nijmegen)
- Some parts of Zeeland (eastern part of Zeeuws-Vlaanderen).
