Modern profile
Back to topModern surname records can be compared with neighbourhood classifications. For Killby, this points to the kinds of places where the surname is most concentrated today.
These neighbourhood labels describe areas, not individual people. They are useful because surnames often cluster through family history, migration, housing patterns and local work. A surname can be strongest in one type of neighbourhood even when people with that name live across the country.
The UK classification gives the national picture. The London classification is more specific to the capital, where housing, age profile, tenure and population mix can look quite different from the rest of the UK.
