The population of the island is approximately 5.8 million people; 4.1 million in the Republic of Ireland (1.6 million in Greater Dublin) and 1.7 million in Northern Ireland (0.6 million in Greater Belfast).
A ring of coastal mountains surrounds low central plains. The highest peak is Carrauntuohill (Irish: Corrán Tuathail), which is 1041 m (3414 feet). The island is bisected by the River Shannon, at 259 km (161 mi) the longest river in Ireland or Britain. The island's lush vegetation, a product of its mild climate and frequent but soft rainfall, earns it the sobriquet "Emerald Isle". The island's area is 84,079 km² (32,477 mile²).
Ireland is divided into four provinces: Connacht, Leinster, Munster and Ulster. In Irish these are referred to as Cúige's ( Cúige - meaning fifths). Previously there were five provinces - Connacht, Munster, Ulster, Leinster and Meath, comprising the counties of Meath, Westmeath and Longford. These were further divided into 32 counties for administrative purposes. Six of the Ulster counties remain under British sovereignty as Northern Ireland following Ireland's partition in 1922 (the remaining 26 forming present-day Republic of Ireland); since the UK's 1974 reshuffle these county boundaries no longer exist in Northern Ireland for administrative purposes, although Fermanagh District Council is almost identical to the county. In the Republic, the county boundaries are still adhered to for local government, albeit with Tipperary and Dublin subdivided (some cities also have their own administrative regions). For election constituencies, some counties are merged or divided, but constitutionally the boundaries have to be observed. Across Ireland, the 32 counties are still used in sports and in some other cultural areas and retain a strong sense of local identity.
Cultural Notes:
The Constitution of Ireland guarantees the rights of the family and the institution of marriage. However, the reality is that social and economic change in recent years has brought about significant changes in family life in the Republic. According to figures published in September, 2004, 31% of all births in the Republic of Ireland occur outside marriage. This compares with 5% in 1980. The average age of mothers having their first child was 30 and the fertility rate is an average of 1.98 children.
In the Republic, divorce became legal on 27 February 1997. The 2002 Census of Population showed that the number of divorced persons in the state stood at 35,100, compared with 9,800 in 1996. The number of separated people, including divorcees, increased from 87,800 in 1996 to 133,800 in 2002. Cohabiting couples made up 8.4% of all family units in 2002 compared with 3.9% in 1996.
Ireland is well supplied with museums and art galleries and offers, especially during the summer months, a wide range of cultural events. These range from arts festivals to farming events. The most popular of these are the annual Dublin Saint Patrick's Day Festival which attracts on average 500,000 people and the National Ploughing Championships with an attendance in the region of 400,000. There are also a number of Summer Schools on topics from traditional music to literature and the arts.
