Working-age households, and more of them renting than the city admits. Just over half own. More than a quarter rent privately. Nearly a third of homes hold exactly one person. The median resident is in their late thirties rather than their sixties. Whatever the seafront implies, nobody ends up here by accident and almost nobody retires here on purpose.
The tenure split, from the 2021 census that supplies every population figure on this page, runs at about 55% owning their home, about 27% renting privately and about 17% renting socially. That last share matters more than it looks. A city with that much social housing has a housing register, a waiting list and a set of pressures that a commuter town simply does not carry, and it shapes who your neighbours are more than any amount of talk about naval heritage.
On age, the median resident is 37, and about 28% of people fall in the twenty-five to forty-four band. That is the working middle of a workforce rather than the tail end of one. Schools are full, buses run at commuter times, and the demographic weight sits with people paying mortgages rather than drawing down pensions.
Income is the number that surprises people. Modelled household income for the financial year to March 2023 came out at around £55,400 gross, before tax, or roughly £40,700 once tax is out of it. That is a household figure rather than a salary, so it usually represents two incomes doing the work, and it describes a period now some way behind us rather than what anyone is earning this month.
Household shapes are varied enough that no single stereotype survives contact with the data. Around 32% of households are one person living alone, and about 13% are pensioners living alone, that second group sitting inside the first rather than alongside it. Couples with children make up about 18%, and lone parent households about 11%. Put plainly, the single largest household type here is somebody on their own, which is a useful corrective for anyone picturing a city of family semis.
On qualifications, around 30% hold a degree-level qualification, about 17% hold none at all, and roughly 4% are full-time students. That is a genuine mix rather than a monoculture, and it is worth resisting the temptation to read anything else into it, because those three figures explain nothing about house prices, schools or crime and are regularly pressed into service to do exactly that.
Health is where the honest answer gets less comfortable. About 82% of residents report good or very good health, with around 5% reporting bad or very bad. Set against England, the Portsmouth local authority records a preventable mortality rate classed as worse, while smoking prevalence is classed as similar. Both of those are local-authority measures covering the whole council area rather than any particular street, and they describe the outcomes a city is producing rather than any judgement about the people producing them.
One technical note that changes how the rest reads. Of roughly 224,000 residents, about 217,300 live in private households and around 6,700 live in communal establishments such as halls, care homes and service accommodation. That last group is large enough to nudge the household figures without altering the story, and it is a reminder that a naval city counts a fair number of people whose address is an institution rather than a front door.
Who lives here is the softest measure on Portsmouth's card, not because of the people but because of the outcomes attached to them: a deprivation profile in the middle of the national range and health measures that sit worse than England on the count that matters most. It is a city of working households doing perfectly ordinary things in a place that has been asked to absorb more than its share of the hard end of that.
