• Opposition to housebuilding is a minority in every seat in Great Britain. A majority of voters support housebuilding or have no view either way.
• It is worth noting, however, that sometimes small pockets of opposition can mobilise through the planning system.
• Of the top 20 seats with the highest levels of opposition, 8 were gained by Labour at the 2024 election with the rest being held by the Conservatives.

Methodology

A 20,000 person survey was conducted by FocalData in the week of the 1st July 2024. MRP (Multilevel Regression with Post-stratification) was used to analyse demographic trends and therefore establish an indicative result for each Parliamentary constituency. This is fundamentally the same technique that is regularly used to derive seat-level estimates of voting intention. It is not a perfect representation of opinion on every proposed housing development - there may be super local factors at play that MRP polling can't capture - but gives you a general sense of an area's disposition based on its demographic make-up.
