Settled, well-qualified households with money and a mortgage to match. Seven in ten own their homes. Half hold a degree. The typical household earns well into five figures before tax. Sevenoaks is where a long career ends up buying a garden.
The 2021 census counted about 27,800 people in about 10,850 households, and it is the source for every population figure on this page. About 69% of households own their home, outright or with a mortgage, and about 19% rent privately, with social housing making up most of the rest. Renting is a stopgap here. People rent in Sevenoaks the way they wait for a table: until the right house comes up.
The median resident is 42. Adults aged 25 to 44 make up about 23% of the population, and that is thinner than the price tags might suggest. Many buyers who can afford Sevenoaks spent their twenties and early thirties earning the deposit somewhere cheaper, and arrive with the children already in tow. The town doesn't get many first jobs. It gets second houses from first-time parents who waited.
Average gross household income, before tax, was about £79,000 in the financial year to March 2023, as modelled by the Office for National Statistics for the area. That is an older snapshot than today's house prices, and it is an average across the town, which means plenty of households sit well above it and some well below. It is healthy money that still gets stretched by what the houses here cost.
Families are the backbone of the town. About 29% of households are couples with children, and about 8% are lone parents. Weekday mornings in Sevenoaks are run by school timetables, not train timetables.
The rest of the household mix is quieter. About 26% of households are one person living alone, and within that group about 14% of all households are a pensioner living alone. Plenty of people raised children here and stayed in the family house after the children left. The spare bedrooms are part of the town's housing stock, whether anyone admits it or not.
Qualifications run high. About 53% of residents hold a degree-level qualification, about 11% have no formal qualifications, and full-time students account for about 1%. Sevenoaks isn't a student town and doesn't pretend to be. The students it has mostly go home at the end of the school day.
About 687 people live in communal settings such as care homes or boarding accommodation, rather than private households. That is small next to the town's population and doesn't change how the shares above should be read.
The people are one of Sevenoaks's real strengths: settled, well qualified and comfortably off, with families at the centre. Not much here is changing fast, and most residents like it that way.
