Income & Affordability Trends
Average household net income in SO40 is £42,546, placing the area above the national average. The current price-to-income ratio of 8.3x has widened from 7.5x in 2016, signalling that property affordability has deteriorated over the past eight years. Rental affordability has similarly declined: the rent-to-income ratio has risen from 28.4% to 29.9%, meaning households now spend a larger proportion of income on rent.
Resident Demographic Profile
The population skews noticeably older than average, with those aged 50–64 and 65+ together accounting for 43.6% of residents compared to 39.4% nationally. The young adult population (16–24) is notably underrepresented at 8.7%. The area shows strong owner-occupation, with 39.4% owning outright and 34.5% owning with a mortgage—well above the national combined figure of 60.7%. Private rented housing is correspondingly lower at 15%. The employment profile reflects the older, more affluent demographic: professionals are less common than nationally, while trades and caring occupations are more prevalent.
