• In the Nice I referendum in 2001, the turnout was 35 per cent. It was rejected by 54 per cent to 47 per cent.
• For Nice II in October 2002, the turnout increased to 49.7 per cent. It was passed by 63 per cent to 37 per cent.
• The assumption since then is that a higher turnout (over 40 per cent) will favour a Yes vote.
• Turnout in rural and western seaboard constituencies was very low for Nice I (below 30 per cent in the two Donegal constituencies). Mobilising this vote is vital for the Yes side.
• Dún Laoghaire and Dublin South West were the only two constituencies (out of 41) to vote Yes in Nice I.
• Dublin South West rejected Nice I by greatest margin (23 per cent).
• In Nice II every one of the 42 constituencies (including the new Dublin Mid West) voted Yes. The closest margins were in Donegal North East (4 per cent) and Dublin North West (8 per cent).
