Inter-marriage
In contrast with both the Republic of Ireland and most parts of Great Britain, where intermarriage between Protestants and Catholics is not unusual, in Northern Ireland it has been uncommon: from 1970 through to the 1990s, only 5 per cent of marriages were recorded as crossing community divides. This figure remained largely constant throughout the Troubles, though it has risen to between 8 and 12 per cent according to the Northern Ireland Life and Times Survey in 2003, 2004 and 2005. Younger people are also more likely to be married to someone of a different religion to themselves than older people. However, the data hides considerable regional variation across Northern Ireland.
