**MRP and RPP estimates**

ComRes, like YouGov in the 2017 general election, employed multilevel regression with poststratification (MRP) as well as regularised prediction and poststratification (RPP) to model voting behavior in every region in Great Britain using large numbers of survey interviews on voting intentions (an approach described as identifying "patterns in responses across [regions] that have similar characteristics, and then work[ing] out the implications of those patterns for each").
