The Roosendaal Group is based on a world wide network, originating from contacts from the International Diaconate Centre (IDC), Diakonia and other diaconal organisations. These (often personal) contacts consist of deacons and diaconal workers from various countries, continents and regions, who are - some more, others less - connected to the aforementioned diaconal organisations.

Below you can find the currently most important regions. Most regions are roman-catholic, albeit some have ecunemism as one of their objectives and develop ecumenical activities.

Besides these regions, the Roosendaal Group also has contacts with deacons from all the other European countries, as well as from several countries in Asia and Oceania.
