Owners, mostly, and mostly past fifty. Around three-quarters own their homes. The typical resident is in their mid-fifties. Close to three in ten households are one person living on their own. It photographs like a surf town and lives like a quiet one.
Tenure sets the tone. About 74% of homes are owner-occupied and about 14% are rented privately, with the rest in social housing. That is a settled place rather than a churning one, and it has a practical consequence for anyone arriving: very little comes up to rent, so the people who move here are overwhelmingly people who bought.
The age profile follows. Census 2021, which is the source for the population figures throughout this answer, puts the median resident at 54, with about 18% of people in the 25 to 44 band. That is a thin slice of early-career adults by most standards, and it shows in what the area is set up to provide. This is a place built around people who have already made their money somewhere else, or who are drawing on it.
Household income across the area was modelled at about £49,600 gross, before tax, for the financial year to March 2023. That describes that year rather than today, and it is a household figure rather than a salary. Set against local house prices, it explains why so much of the property here changes hands to people arriving with equity rather than to people already living in the postcode.
Household shapes are small. About 29% of households are a single person living alone, and about 18% are a pensioner living alone, which is a subset of that first figure rather than an addition to it. Couples with children account for about 14%, and lone-parent households about 8%. A place of ones and twos, with the family homes a minority of the doors.
On qualifications, about 34% of residents hold a degree-level qualification and about 15% hold none at all, with full-time students at about 2%. That is a mixed picture rather than a uniform one, and the two ends of it tend to live in the same lanes rather than in different halves of the area.
Health reads well locally and unremarkably at county level. About 80% of residents rate their health as good or very good, and about 6% as bad or very bad. Across Cornwall as a whole, smoking prevalence and the preventable mortality rate both sit similar to the England average. Those last two are local-authority measures with a national benchmark, not readings taken in Porthleven, so treat them as the county's standing rather than the village's.
Who lives here is the least flattering part of this area's numbers, and not because of the people. An older, owner-heavy population with modest household incomes sitting under expensive coastal property is a combination that leaves the area below average on prosperity while looking, from the harbour wall, like the opposite.
