Voluntary enlistment
In Northern Ireland, approximately 38,000 people volunteered for service in the British armed forces between 1939 and 1945 - including 7,000 women. There were in fact more volunteers from neutral Éire with approximately 43,000 men and women enlisting in the British armed forces during the war.[5] Some evidence suggests that the numbers of volunteers from Northern Ireland in the Second World War was considered disappointing by contemporary standards. [Wiki]
But pro capita, the numbers from N. Ireland appear as 3.4%, from Eire 1.4%. - so you're still right !
