The gap between the proportion of Protestants and Catholics in Northern Ireland has narrowed, according to new census figures.

The census reveals that 48% of the resident population are either Protestant, or brought up Protestant, while 45% of the resident population are either Catholic, or brought up Catholic.

Figures show that 5.6% belong to neither faith, nor have been brought up in any religion.

The Northern Ireland census was held on 27 March last year.

The 2011 census was the first time a question on national identity was asked.

Of those questioned, 40% said they were British only, with the remaining 8% choosing British along with another one of the identities, such as British and Irish or British and Northern Irish.

A quarter of the population defined themselves as Irish only, while 21% said they were Northern Irish only.

In terms of religion, in the 2001 census 53% of the population was Protestant with 44% Catholic.
