Over the course of the referendum I wrote several long pieces analysing opinion polls as they appeared in the newspapers to glean useful information about how the campaign for a Yes vote was doing, where we were stong, what weakenesses existed and what tactics this information suggested. I’ve gathered all these pieces together below in reverse order, the first has a lot of details on methodology and context that is not repeated in the later pieces.
The polls appear to have been very accurate in particular those carried out by Red C and also Behaviours and Attitude. Both companies showed likely results very close to the final outcome (66.4% Yes) if you presume the Yes campaign won most of the Don’t Knows over the 3 months between the start of serious campaigning around March 8th and the referendum in June.
