Older than the harbour photographs suggest, and considerably more settled. Two-thirds own their homes. The typical resident is in their early fifties. More than a third of households are a single person. Newlyn is a town of long residence rather than a town of arrivals, and its rhythm follows from that rather than from the boats.
On tenure, about 67% of households own their home, about 21% rent privately and about 12% rent from a social landlord. That ownership share is high for a coastal town with this much holiday-let activity around it, and it means most of the housing here is occupied by people who expect to still be here in a decade.
The age profile is the most consequential number on this page. The median age is 53, and only about 19% of residents fall into the 25 to 44 band. A town where fewer than one in five adults sits in the prime family-forming years is a town with quiet weekday mornings, thin queues at the school gate, and a labour market that depends on people travelling in.
Income is modest. Modelled gross household income, before tax, averaged about £41,000 in the financial year to March 2023, with about £33,000 of that remaining after tax on the same modelling. That is the most recent year the modelling covers rather than a description of today, and it is deliberately given without a national comparison, because the gross figure most readers carry in their head for the country as a whole is usually wrong in the direction that flatters.
Family structure is where the town differs most from the average. Around 10% of households are a lone parent with dependent children, and around 12% are a couple with children. Those two together are a smaller share of the town than single-person households alone.
Every population figure here comes from Census 2021. On that count, about 36% of households are one person living alone, and about 19% are a pensioner living alone, which is a subset of the first figure rather than an addition to it. Add the couples with children at about 12% and the lone parents at about 10%, and the shape is clear: this is a town of small households, many of them one person, in housing built for larger ones.
On qualifications, about 33% of residents hold a degree-level qualification, about 17% hold none, and about 1% are full-time students. Both ends of that are substantial, which is what happens when a working port and a long-standing artistic reputation share the same streets. It describes a mix, not a hierarchy.
Health self-reports land on the ordinary side: about 77% of residents describe their health as good or very good, and about 7% as bad or very bad. Comparisons on the wider measures are drawn at Cornwall level rather than Newlyn's own, and on both smoking prevalence and preventable mortality the council area sits similar to England. Those are figures about a county of more than half a million people, and they say nothing about anyone's street.
Of the 3,881 residents counted here, 29 live in communal establishments rather than private households, which is small enough to leave every share above unaffected.
Taken on the standard measures, the population profile here is one of Newlyn's weaker dimensions: an older, low-turnover town on modest incomes, where the strength is stability and the cost is how few people are in the years when a town usually renews itself.
