This article provides an overview of multilevel regression and post-stratification. It reviews the stages in estimating opinion for small areas, identifies circumstances in which multilevel regression and post-stratification can go wrong, or go right, and provides a worked example for the UK using publicly available data sources and a previously published post-stratification frame.
