Owner-occupiers in their late forties, mostly. About four in five households own their home. The median resident is 48. The typical household income is around £57,000. This is a settled, middle-aged, owning population, the kind of place where the school catchment matters more than the nightlife and the second car matters more than the train.
Home ownership runs at about four in five households, well above the national norm. Private renting covers about one in seven homes, and social renting about one in twenty. The rental pool is shallow, and when listings do appear they tend to clear fast. The composition matches what you would expect from a 1950s-to-1980s estate village where the original buyers stayed and the next generation upgraded into bigger versions of the same houses on the same streets.
The median age sits at 48, which is older than the Hampshire average and well older than the national one. The 25-to-44 working-age band makes up about a quarter of residents, which is on the lower side. The age skew is what happens when a place stops building much new housing, the original families age in place, and the children move out for university or for cheaper rents elsewhere. The garages got fuller and the prams got rarer.
Median household income lands at around £57,000, which is above the national figure and broadly consistent with the borough's owner-occupier suburbs. Combined with a multi-car rate of about half the households and an unemployment rate of under 2 percent, the picture is a working population in stable jobs, mostly commuting by car, paying down a mortgage or sitting on a paid-off one. The household at the median is not wealthy but is not stretched in any obvious way either.
Household make-up is mixed in a way the dominant-stereotype family-suburb label undersells. About one in five households is a couple with dependent children, the classic estate-village family. About three in ten households are single-person. About one in six of all households is a single pensioner, which is the other side of the ageing-in-place story. About one in thirteen is a lone-parent household. Overcrowding is very low, affecting well under 2 percent of homes. The mix is normal-distribution suburbia rather than family-only suburbia, and that matters for the kind of street you actually walk down.
The verdict on who lives here is excellent, scoring five out of five on the data, mainly because the deprivation profile sits in the very top deciles nationally, the health profile is strong, and around a quarter of the population holds a degree. Cowplain is a settled, owning, middle-aged working population, neither glamorous nor struggling, and the data is honest about both halves of that description.
