In the IPH Community Profiles Tool, there are three geographies: All-Ireland, Northern Ireland (26 Local Government Districts), and Republic of Ireland (34 Administrative Counties and Cities).
For some indicators, data are not available at the level of these regions. In these cases the value for a wider area (e.g. the four Northern Ireland Health Trusts) is superimposed onto its constituent smaller areas (e.g. the 26 Local Government Districts). Where this has been done, the metadata provides the information.
North-South comparisons are only possible with all-Ireland indicators.
