Working families who own their house and don't make a fuss about it. Two-thirds own their home. The typical resident is under forty. About one household in five is a couple with children. It isn't a town of students or retirees. It's the stretch of life in between, the one that comes with a mortgage.
Ownership is the norm. About 67% of households own their home, about 18% rent privately and about 13% rent from a council or housing association. That's a settled town, not a transient one, and the people on most streets expect to still be there when the fence needs replacing.
The age profile sits in the middle. The median resident is 39, and about 28% of people are aged 25 to 44, the years of first homes, young children and trying to remember when anyone last slept through the night. The town is neither young enough to be lively at midnight nor old enough to be quiet by nine.
On income, modelled gross household income, before tax, averaged about £57,700 in the financial year to March 2023. That's a household total rather than a salary and it's a few years old, so read it as a comfortable working-town figure, not a wealthy one. Nobody here is flashing money about, and nobody is expected to.
Household make-up follows the same pattern. All the figures in this answer come from Census 2021. About 22% of households are couples with dependent children, and about 11% are lone parents. About 26% of households are one person living alone, and within that group about 12% of all households are a pensioner living alone. The family home is the backbone of the town, and a lot of the single households are people whose families grew up and moved out.
On qualifications, about 24% of adults hold a degree and about 20% have no formal qualifications. Full-time students make up about 2% of residents, which confirms what the high street already suggests: there's no university here, and nobody pretends otherwise. The mix leans towards trades, offices and warehouses rather than lecture halls, which fits the town's history of making bricks and paper and moving things around.
Sittingbourne sits squarely in the middle on most measures: middling on income, middling on qualifications and settled in its ways. That makes it predictable in a way plenty of buyers actively want.
