People who have finished moving. Roughly six in ten households own their home. The typical resident is closing in on fifty. More than a third of households contain exactly one person. This is a town that people arrive at rather than pass through, and the housing market has been arranged around that for a century.
On tenure, the census in 2021 recorded around 63% of households owning outright or on a mortgage, with about 18% renting privately and a further 18% in social housing. That social share is high for a market town and is one of the things that makes Dorchester a genuinely mixed place rather than a heritage display case.
The age profile leans older. The typical resident is 49, and only about 21% of the population falls in the twenty-five to forty-four band that most towns build their evening economy around. That is the arithmetic behind the shop shutters coming down early, and it explains a great deal about the town's temperament.
Household income across the area came to about £56,000 a year before tax, as modelled by the Office for National Statistics for the financial year to March 2023. That is a gross figure describing 2023 rather than today, so treat it as the shape of the place rather than a current bank balance. Net of tax, the same modelling puts households at around £42,000.
Household make-up, again from the 2021 census, is where the town shows its hand. Around 36% of households are single people, and roughly 20% are pensioners living alone, that second figure being a subset of the first rather than something to add to it. Couples with dependent children make up about 16%, and lone parents around 10%. One in five households being a pensioner on their own is a large number for a town with this much housing stock, and it shapes everything from the bus timetable to the queue in the pharmacy.
On qualifications, around 37% of residents hold a degree-level qualification, about 14% hold none, and roughly 2% are full-time students. That is the spread of a county administrative centre with a hospital attached rather than a university town, and the absence of a student population is why the place empties on a weeknight.
Health self-reports are good. Around 80% of residents describe their health as good or very good, with about 5% reporting bad or very bad health. At local-authority level, Dorset comes out better than England on preventable mortality and similar to England on smoking, with roughly 10% of adults smoking. Those are county figures with an England benchmark rather than Dorchester's own.
One figure worth holding while reading the rest: 311 people here live in communal establishments rather than private households, in care homes, halls and similar. It is a small number against a population of 21,358, but it sits behind the older age profile rather than alongside it.
The population here is middling in the honest sense: comfortable rather than wealthy, older than average, well qualified, and settled enough that turnover is somebody else's problem. Nobody moves to Dorchester to reinvent themselves, and the people already here would consider that a compliment.
