This map was compiled by The Detail using data requested from the Department of Education. It gives a breakdown of the number of newcomer pupils attending 1,549 schools in Northern Ireland during the 2012/13 school year. Where two or more schools share an address, we have added street numbers to ensure they don't overlap on the map. This means not all addresses are exact. Some close addresses still overlap so look out for '1 of 2' at the top of some information boxes. We cannot calculate a percentage for schools with less than 5 newcomer pupils as the department will not provide the exact figure for these schools - they appear as purple markers on the map. Click on the coloured markers to see the data for your local schools.
