Who lives in Castle Cary?

For anyone buying or renting in Castle Cary.

People who have finished moving. Two thirds own their homes. The typical resident is in their early fifties. A third of households are one person living alone. This is a town of arrivals who have already unpacked, not a place anyone passes through on the way to somewhere better.

The tenure split says most of it. Around 67% of households own their home, around 18% rent privately and around 13% rent from a social landlord, from the 2021 census, which is the source for the population figures throughout this answer. That is a town where the majority of front doors belong to the people behind them, and it explains a lot about the pace of the place. Owner-occupied towns turn over slowly.

The age profile follows from that. The median resident is 53, and only around 18% of the population falls in the 25 to 44 band, which is the thinnest slice of the town by some distance. Nobody planned this. It is what happens when the housing stock is family-sized, the ownership rate is high, and the people who bought in stayed put.

Income sits comfortably above where the countryside stereotype puts it. Modelled gross household income for the area, before tax, ran at around £58,200 in the financial year to March 2023. That figure is modelled for the wider statistical area rather than measured street by street, and it describes 2023 rather than today, so treat it as the shape of local earnings rather than a payslip.

Household make-up is where the town gets interesting. Around 33% of households are a single person living alone, and around 19% of all households are a pensioner living alone, which is a subset of that first figure rather than an addition to it. Around 15% are couples with dependent children and around 8% are lone-parent households. A town where one household in three is a person on their own is a different social proposition from a town of family semis, even when the houses look identical from the road.

Qualifications split fairly evenly across the range. Around 34% of residents hold a degree-level qualification and around 17% hold none at all, with full-time students at around 1%. That is a broad spread rather than a graduate enclave or a place education passed by, and it is the sort of range that produces a functioning town rather than a commuter estate with opinions.

Health reports well. Around 81% of residents describe their health as good or very good, with around 5% describing it as bad or very bad. At the wider Somerset local authority level, which covers far more than this town, preventable mortality sits better than the England benchmark and smoking prevalence at around 11% sits similar to England. Those are county figures with a national comparison attached, not a reading of this particular postcode.

One number worth holding while reading the rest: around 107 residents live in communal establishments rather than private households, with six care homes in the area. It is a small share of a town of just under 5,000 people, but it is part of why the age profile skews the way it does, and it means a slice of the population is not represented in the household statistics at all.

Who lives here is middling in the statistical sense and settled in every other one: older than most places, comfortably housed, and largely done with the business of relocating. If you are 28 and hoping to find a crowd your own age already established, the numbers here are not on your side.
