Hornsey was a much larger original ancient parish than today's electoral ward of the same name. These entities are smaller than the Municipal Borough of Hornsey which co-governed the area with Middlesex County Council from 1889 until 1965, since when the name refers, as a minimum, to the London neighbourhood with a high street at its traditional heart to the west of Hornsey railway station. Its parish ranked sixth in size, of more than forty in Ossulstone, the largest hundred in Middlesex and was a scattered semi-rural community of 2,716 people in 1801. By 1901 the population had risen about eightfold in forty years, reaching 87,626, by which time new localities/districts, mainly Crouch End and Muswell Hill, were popularly becoming considered distinct from Hornsey. The N8 postcode district, the current form of Hornsey ward as devised from time-to-time for equal representation (electorate) across wards of the Borough, and the choice of other railway and tube stations towards, on these definitions, outer parts create conflicting definitions of Hornsey and it is unclear whether since 1965 the term is distinct from Hornsey Village, a term unrecognised by some residents.
