Population, size, average age and other top tidbits about the island of Ireland you never knew
Ireland’s Central Statistics Office (CSO) and the Northern Ireland Statistics and Research Agency (NISRA) has released a report titled “Census 2011 Ireland and Northern Ireland” giving comprehensive results from the island for the first time.
Here’s a breakdown of the top results and some other facts and figures that may surprise you.
Ireland is 32,595 sq miles (84,421 km²)
At its widest the island is about 174 mi (280 km). At its longest (north-south) it is 302 mi (486 km).
It has over 3,000 miles of coastline.
6.4 million in total.
This comprises 4.6 million people in the Republic of Ireland (72 percent) and 1.8 million in the North.
To put these figures into context consider the fact that New York City has a population of 8.337 million and London is home to 8.307 million.
The overall population density of Ireland is 78 persons per square kilometer.
The official languages are Irish and English but most of the population uses English. Irish is a compulsory subject in all schools that receive state funding.
The median age in Ireland is 34.
This is lower than any other European Union member state.
Catholicism remains dominant at 84 percent.
Protestants and other Christians represented 42 percent of the population of Northern Ireland while Catholics accounted for 41 percent, with the remainder made up mainly of those with no religion (10%) or not stated (6.8%).
Marriage and divorce:
In Northern Ireland the number of single people has increased by 20 percent since 2001. While that figure in the Republic is up by 15 percent.
There were 56,900 separated and 78,000 divorced persons in Northern Ireland, representing 9.3 percent of those aged 15 and over, while the comparable figures for Ireland were 87,800 persons divorced and 116,200 separated which together accounted for 5.7 percent.
