In terms of systematic differences such as demography, what connects the regions that turned orange and what connects those that turned red, during the 2019-2024 UK election cycle?
Looking at the demographic maps, it seems the least and most affluent regions voted Labour. The surveys suggest more educated voters vote Labour and Lib Dems more frequently. However, while age, affluence and education of a the regions all seem highly correlated, the map of the election results seems somewhat arbitrary, with Lib Dems winning regions in the South West and Conservatives winning regions on the East.
Are there some other demographic or historic factors that explain the Lib Dems' success in the South West & less Conservative losses on the East?
