U.K. election: What is the MRP method of modelling opinion polls? | Explained

As Britain's election nears, Labour holds a steady 20-point lead in opinion polls, suggesting a potential landslide victory under Keir Starmer. Due to the UK's electoral system, which favors local wins over national vote shares, pollsters rely on MRP (Multilevel Regression and Post-stratification) modeling. This statistical method uses national survey data to predict outcomes at a local level, considering factors like demographics and voting history to provide more accurate election forecasts.
