Your questions: John Curtice
Professor John Curtice from Strathclyde University is widely regarded as the UK's foremost psephologist.
He has been studying voting behaviour since he was a 10-year-old in Cornwall watching the 1964 UK general election count, which was eventually won by Harold Wilson.
In the late 1980s he came to Scotland to continue his political number-crunching in Glasgow.
He tells BBC Scotland's Andrew Kerr it has been "absolutely fascinating" to watch the constitutional change in Scotland over the past 25 years.
In this webcast, Prof Curtice answers questions from BBC news website readers on voting trends around independence, whether men are more likely than woman to vote Yes and if pro-Independence supporters are stronger in their convictions than those in the No camp.
He is also asked about votes for under 18s, votes for people outside Scotland, devo plus and whether Scotland is actually pro-Europe.
