The graph below shows What Scotland Thinks’ latest Poll of Polls and how it has evolved over time.
The latest Poll of Polls is based on two polls by ICM, two by Survation, one by YouGov and one by Opinium, The polls were conducted between 5 and 12 September.
The following new polls have been added to the calculation: Survation for Better Together, Opinium for The Observer and ICM for the Sunday Telegraph, all first released on September. Because the last of these polls had a smaller sample size than usual, it has been included with a weight of 0.7.
This calculation will be updated when the results of a further poll are released later tonight or tomorrow.
