As the formal definition of “urban” areas in Ireland (RoI and NI) does not include many areas at the periphery of towns and cities, urban and rural populations were distinguished by population density (Table 2.4), based on the estimated average number of inhabitants in 1995-2007. Three categories were created for analysis, with the cut-off points (<1 person/hectare, 1-15 persons/hectare, >15 persons/hectare) chosen to give an approximately equal population in each group.

population density | no. of cancer cases* | estimated average population | % of total population | number of EDs and wards |
<1 person/ha | 121,810 | 2,004,451 | 36% | 2,892 |
1-15 persons/ha | 90,597 | 1,644,792 | 29% | 403 |
>15 persons/ha | 129,380 | 1,940,844 | 35% | 642 |
