By 1881 the population of Newry had reached 15,590. Newry Urban District Council was unusual in that during the period from the 1920s to the 1960s it was one of only a handful of councils in Northern Ireland which had a majority of councillors from the Catholic/Nationalist community. (The others were Strabane UDC and a handful of rural district councils.) The reason, according to Michael Farrell, was that this community formed such a large majority in the town, around 80% of the population, making it impossible to gerrymander. Also an oddity was that for a time it was controlled by the Irish Labour Party, after the left wing of the Northern Ireland Labour Party defected to them in the 1940s.
