Income & Affordability Trends
Average net household income of £54,011 is among the highest nationally, reflecting the affluent demographic profile of the area. The price-to-income ratio of 14.5x has deteriorated since 2016 (when it stood at 13.2x), signalling tightening purchase affordability despite strong incomes.

The population is notably older than the national average, with over a fifth aged 65 and above compared to 19.6% nationally, whilst the under-25 age group is substantially underrepresented. Housing tenure reflects wealth: 39.6% own outright (against a national 33.7%), and mortgage ownership is elevated at 32.7%. The employment mix skews heavily towards senior roles—professionals comprise 24.2% and managers 23.5%, nearly double the national managerial share—whilst trades and elementary occupations are significantly underrepresented.
