The voting is over, and now it's time to watch the results come in.
There will be separate counts in each of Scotland's 32 local authorities, and the anticipated timetable (here) for each count is below. Three of the largest authorities—Glasgow, Edinburgh and Aberdeen—will be among the last to come in, and together account for a about a quarter of the overall result. So those of you that aren't planning to stay up all night could set your alarms for 5am to catch the big declarations that are likely to swing it one way or the other.
Fairly obviously, there are some areas where the Yes vote will be relatively strong, and others where it will be weaker. So I've asked myself about the best yardstick to measure the individual declarations against. It's not very helpful to use the 1997 referendum results because there were two main factors driving the Yes vote: the first was those who wanted more autonomy for Scotland; but the second was those who might not have been sure about a Scottish Parliament, but who voted Yes out of loyalty to Labour. It had been one of New Labour's keystone pledges, Tony Blair had only just been swept into power on a wave of optimism, and people trusted him. The highest Yes/Yes vote was in the (then) Labour fortress of Glasgow, at 75%, with West Dunbartonshire, North Lanarkshire, and East Ayrshire also above 70%. But Labour voters will be much more divided this time round.
Unsurprisingly the polls show a strong correlation between voting SNP and voting Yes to independence. So the best yardstick I can think of is to compare the Yes vote against the percentage of first preference vote for the SNP in the 2012 local elections. However this doesn't work well for Orkney, Shetland and Na h-Eileanan Siar, because these councils are dominated by independent councillors, so I've taken a guess based on the SNP vote in the 2011 election, shown in brackets. It probably won't make much difference if I've got these wrong, because they account for very little of Scotland's overall population.
My basic assumption is that the "spread" of votes will probably be no more than a third. So to achieve a 50/50 overall result, the Yes vote would be up towards 67% in places where the SNP polled well in 2012 such East Ayrshire and Clackmannanshire; but would be down towards 33% in areas with little SNP support such as Dumfries and Galloway. On this basis I've worked out a "Yes target" for each council area. If the Yes vote consistently comes in higher than these targets, especially in the more populous council areas, Yes are on course for an overall victory.
