Census comparison shows differences between Republic and NI
Significant gaps in terms of average age, population density and household size
A comparison of the results of the 2011 censuses in the Republic and Northern Ireland shows clear differences between life in the two near neighbours.
The report by the Central Statistics Office (CSO) and the Northern Ireland Statistics and Research Agency (NISRA), published today, highlights clear gaps between the two jurisdictions when it comes to age, gender, marital status, population density and household size.
The population of the island was 6.4 million at the time of the two censuses, carried out within weeks of each other in 2011, with the Republic accounting for 72 per cent (4.6 million) of the total and Northern Ireland 28 per cent (1.8 million).
The report points out that, since 2002, the population in the Republic increased at about two and a half times the rate of Northern Ireland, at 17 per cent and 6.9 per cent respectively.
Across the island, the highest rates of population growth were seen in Fingal (79 per cent), Meath (75 per cent) and Kildare (71 per cent) over the last 20 years with Belfast (-4.1 per cent) and Cork city (-6.3 per cent) the only areas to experience a decline.
The population density for the island as a whole stood at 78 persons per km2, an increase of 25 per cent since 1991. The population density in Northern Ireland stood at 134 persons per km2; exactly double that of the Republic at 67 per km2.
Strong population growth in the Republic saw population density increase by 30 per cent between 1991 and 2011. The Northern Ireland rate went up 13 per cent in that period.
There are more women than men in both jurisdictions (3.24 million to 3.16 million across the island) with Northern Ireland recording 961 men for every 1,000 women and the Republic reporting 981 men for every 1,000 women.
The median age, the point at which half of the population is younger and half is older, was 34 in the Republic, the lowest of any EU member state. The median age in Northern Ireland, while higher at 37, was also comfortably lower than the EU average of 41.
“The highest median age can be seen in eastern areas of Northern Ireland, in particular in Ards, Castlereagh, Larne and North Down at 41. The lowest median age of 31 was found in Galway City,” the report states.
Children aged up to 12 years accounted for 19 per cent of the population of Ireland, compared to 17 per cent in Northern Ireland, which the report says reflected higher birth rates in Ireland in recent years. Over 65s accounted for 15 per cent of Northern Ireland’s population, compared with 12 per cent of that in the Republic.
