:The wording that was reverted was as follows:


Northern Ireland (, Ulster Scots: Norlin Airlann) is a part of the United Kingdom of Great Britain and Northern Ireland[2]...

2 In common with the other constituent parts of the United Kingdom, Northern Ireland is sometimes referred to as a "country" (example). The UK government also refers specifically to Northern Ireland as being a "province" (UK: example; NI: example) or a "region" (UK: example; NI: example). Regardless of the choice of term, it is likely to be unsatisfactory and can imply a preferred political perspective:
 "One problem must be adverted to in writing about Northern Ireland. This is the question of what name to give to the various geographical entities. These names can be controversial, with the choice often revealing one's political preferences. ... some refer to Northern Ireland as a 'province'. That usage can arouse irritation particularly among nationalists, who claim the title 'province' should be properly reserved to the four historic provinces of Ireland-Ulster, Leinster, Munster, and Connacht. If I want to a label to apply to Northern Ireland I shall call it a 'region'. Unionists should find that title as acceptable as 'province': Northern Ireland appears as a region in the regional statistics of the United Kingdom published by the British government." - J. Whyte and G. FitzGerald, 1991, Interpreting Northern Ireland, Oxford University Press: Oxford
 "One specific problem - in both general and particular senses - is to know what to call Northern Ireland itself: in the general sense, it is not a country, or a province, or a state - although some refer to it contemptuously as a statelet: the least controversial word appears to be jurisdiction, but this might change." - S. Dunn and H. Dawson, 2000, An Alphabetical Listing of Word, Name and Place in Northern Ireland and the Living Language of Conflict, Edwin Mellen Press: Lampeter
 "Next - what noun is appropriate to Northern Ireland? 'Province' won't do since one-third of the province is on the wrong side of the border. 'State' implies more self-determination than Northern Ireland has ever had and 'country' or 'nation' are blatantly absurd. 'Colony' has overtones that would be resented by both communities and 'statelet' sounds too patronizing, though outsiders might consider it more precise than anything else; so one is left with the unsatisfactory word 'region'." - D. Murphy, 1979, A Place Apart, Penguin Books: London and it is situated in the north-east of the island of Ireland. It shares a border with the Republic of Ireland to the south and west. At the time of the 2001 UK Census, its population was 1,685,000, constituting between a quarter and a third of the island's total population and about 3% of the population of the United Kingdom.


Snowded, what is it that you find incorrect about this? The phrasing used is verbatium copy of how Northern Ireland is described on that 10 Downing Street webpage you keep wheeling out:"Northern Ireland is a part of the United Kingdom..."
Your approach is based on a cherry picking of sources. The copy you oppose is neutral, source-based and explains the issue clearly, factually and fairly. If there are specific issues with it then critique it. Don't just say, "I don't like it". rannṗáirtí anaiṫnid (coṁrá)
