According to recently released data under government Freedom of Information laws Bill Clinton thought Unionists would do a deal.
Bill Clinton said: “I think they’re worried about being rendered irrelevant in 20 years, given the way the demographics are going, it’s better to make a deal now rather than later... If you look at it, their popular majority is eroding over time with the increasing birth rates, so now is the time.
“You’ll have to come up with some sort of creative dual relationship.”
According to figures published on the University of Ulster-run CAIN website, the proportion of Catholics in Northern Ireland had risen from 33.5 per cent in 1926, to 38.4 per cent by 1991.
Meanwhile, those belonging to the three main Protestant denominations (Presbyterian, CoI and Methodist) dropped from 62.2 per cent to 42.8 per cent in the same period.
The recent NI Census shows 45% of Northern Ireland's population were Catholic or brought up Catholic, 48% were Protestant or brought up Protestant or other Christian and 5.6% neither belonged to nor had been brought up in a religion.
