Older than the brochure implies, and more settled than almost anywhere. Seven in ten own their homes. The typical resident is in their late fifties. A third of households are one person, and one household in five is a pensioner living alone. This is not a town people move to for a career. It is a town people move to once the career has stopped setting the agenda.
On tenure, the 2021 census puts owner-occupation at about 70% of households, with roughly 17% renting privately and about 12% in social housing. That ownership level is the single most important fact about the population here, because it means most of the town is not exposed to the rental market at all and has no particular reason to worry about it. The 17% who are exposed are competing for a small pool of long-term lets in a place where letting to visitors pays better.
The age profile follows from that. The median resident is 57, and only about 16% of the population is aged between 25 and 44. That band is the one that fills schools, staffs the shops and turns up to things on a Wednesday evening, and it is thin here. Every seasonal business in the town knows exactly what that means in July.
Modelled household income for the area ran at about £48,100 gross, before tax, in the financial year to March 2023. That describes a specific year rather than today's pay packets. It also sits alongside a housing market priced by people arriving from elsewhere, which is the tension underneath almost every conversation about who can afford to stay.
Household make-up is where the town's character shows most plainly. About 35% of households are a single person, and within that figure about 21% are a pensioner living alone. Couples with dependent children account for about 12% of households, and lone-parent households about 8%. A town where one person households outnumber families with children by that margin runs at a different rhythm: quieter evenings, fuller daytime cafes, and a volunteer register doing a great deal of what a larger workforce would otherwise do.
On qualifications, about 32% of residents hold a degree-level qualification and about 17% have none, with full-time students at roughly 1%. That is a mixed picture rather than a polarised one, and the student figure confirms what the absence of a college in town already tells you. Nobody is here for the nightlife of a university term.
Health self-reporting is reasonable: about 77% of residents describe their health as good or very good, with about 6% reporting bad or very bad health, which is a decent result for a population this age. Across the Dorset local authority as a whole, preventable mortality sits better than the England average, and smoking prevalence runs at about 10%, which is similar to England. Those two are county-level measures against a national benchmark rather than a Swanage-specific reading, and they describe the health system and population of a large rural authority.
Who lives here is neither this town's strongest suit nor its weakest. It is a stable, well-housed, largely retired population with a genuine gap where the under-forty-fives should be, and anyone moving in should be honest with themselves about which of those two facts they are signing up for.
