The main religious denominations are organised on an all-Ireland basis. They are as follows:
The combined Catholic population of the Republic and of Northern Ireland is about
3.9 million. There are approximately 1,300 parishes served by about 4,000 priests. The rate of
religious practice among Irish Catholics is one of the highest in the world. There are approximately
20,000 men and women in various religious orders of priests, brothers and nuns.
The Catholic Church is closely involved in the provision of education and health services. This
involvement began as a service to the poor but expanded considerably over the years. The Church
cooperates with State agencies in many areas such as education and welfare.
The Irish Catholic Church sends missionaries to every continent. Today there are over 4,500
Irish missionaries working in 85 different countries throughout Africa, Asia, Central and South
America, and Oceania.
