I’ve combined the data from Kathryn Torney’s 2012 guardian article (https://www.theguardian.com/news/datablog/2012/nov/24/religious-divide-northern-ireland-schools) and more recent data for 2017 from OpenDataNI to illustrate the depth of the divide that still exists in education here in Northern Ireland. I've produced an interactive chart where data can be viewed for one of three points in time, and filtered by management type, school type, age etc.
