Mill Hill is home to about 31,600 people, mostly educated owner-occupiers in early middle age with comfortable incomes. Six in ten own their home. Half have a degree. The typical resident is in their late thirties. It is a suburb of professionals who stopped renting in town and have no plans to go back.
The 2021 census, the source for every population figure on this page, put home ownership at about 63% of households. About 26% rent privately and about 10% rent from a council or housing association. That is a solid owning majority with a real rental market alongside it, mostly in the flats around the Broadway, and it keeps Mill Hill from becoming a suburb where everyone has lived on the same road since the bypass opened.
The typical resident is 38, and about 29% of people are between 25 and 44. Those are the years of first mortgages, second children and a long argument about loft conversions, and Mill Hill has a lot of people in the middle of all three.
Household income averaged about £78,400 a year before tax in the financial year to March 2023, a modelled figure from the Office for National Statistics spread across the area's neighbourhoods. That is gross pay, so the take-home that services a Mill Hill mortgage is a good deal smaller. A comfortable income, in a place where comfortable is the entry fee.
There are 11,851 households in Mill Hill. Couples with dependent children make up about 25% of them and lone parents about 11%, so roughly a third of homes have children in them, enough to fill the school gates and the parks after four.
Living alone is the other big group. About 26% of households are one person, and within that, about 11% of all households are pensioners living alone. The family homes and the single households often share a road: the semi with the trampoline, and next door the house someone has lived in for forty years after the children left.
Education is high. About 51% of residents aged 16 and over hold a degree or equivalent, about 14% have no formal qualifications, and only about 2% are full-time students. Without a university in the area there is no term-time population, so the people on the bus in September are the same ones who were on it in July.
Health is good. About 87% of residents described their health as good or very good at the census, and about 4% as bad or very bad. Barnet, the borough that holds the wider health records, comes out better than England on deaths from preventable causes and similar to England on smoking, at about 9% of adults. A borough-wide figure covers everywhere from Mill Hill to the busier parts of Barnet, though, and says nothing on its own about the next street.
Mill Hill's residents make for a solid, above-average place to live among: well-qualified, mostly healthy and comfortably off, with enough renters, pensioners and young families in the mix to stop it turning into one long dinner party.
