This map has been compiled by The Detail to illustrate the financial impact of welfare reform in Northern Ireland. The data comes from research carried out by Sheffield Hallam University, commissioned by NICVA. As well as the overall estimated financial loss by council area, there is also a breakdown for the five benefit types set to have the biggest overall financial impact on the Northern Ireland economy. The deprivation ranking is based on the % of each council areaâ€™s super output areas in the 30% most deprived in NI. Click on the coloured markers to read data for each council area.
