Older people who own their homes, and not many of them. Three quarters are owner-occupiers. The typical resident is in their mid-fifties. Nearly a third of households are one person living alone. This is not a village in the middle of raising a generation, it is a village that finished doing that a while ago and kept the houses.
Ownership dominates. The 2021 census, which is the source for the population figures throughout this answer, records 74% of households owning their home, with 18% renting privately and 8% in social housing. That is a settled place where most people are not going anywhere, and it is also a place with a thin rental market for anyone hoping to try before they buy.
The age profile explains most of the rest. The median resident is 56. Only 14% of the population falls in the 25 to 44 band, which is the group that normally supplies the young families, the evening trade and the person who volunteers to run things. Calstock has fewer of them than almost any suburb you could compare it against.
On money, modelled household income for the area was around £46,000 gross in the financial year to March 2023, or about £37,000 after tax. That describes that year rather than today. It is a comfortable rural figure rather than a wealthy one, and it sits alongside house prices that reward people arriving with equity from elsewhere.
Households are small. Around 10% are lone-parent households, and the family-with-children share is modest at 14% of households being couples with dependent children.
The fuller picture from the same census: 30% of households are a single person living alone, and 14% are a single pensioner, that second group being part of the first rather than added to it. Put those next to the 14% who are couples with children and the shape of the village is clear. More front doors here open onto one person than onto a family.
Education is the number that surprises people. Some 44% of adults hold a degree-level qualification, while 12% have no qualifications at all and 1% are full-time students. That is a well-qualified rural population, which fits a place where more than a third of workers do their jobs from home, and it says nothing whatever about anybody's neighbours beyond the fact that a lot of them studied.
Health reads as unremarkable, in the good sense. Some 79% of residents report good or very good health and 5% report bad or very bad. Wider indicators for the Cornwall local authority, not the village itself, put smoking at 12% and preventable mortality at a level classed as similar to England on both counts. Average, in other words, with no local flag either way.
Community is the weakest dimension in Calstock's local picture, and the honest reason is structural rather than personal. An older, smaller, heavily owner-occupied population with few people in their thirties is a lovely place to retire into and a quiet one to arrive in at thirty-two with a pushchair and an expectation of finding your people.
