How the similarity is worked out

Alike on the Census, which is not the same as alike to live in.

Every neighbourhood is described by its shares across the Census themes above — tenure, housing, cars, household make-up, age, ethnic group, qualifications, work, health and deprivation — each theme weighted equally, which is the approach ONS takes in its own Output Area Classification. The neighbourhoods listed are the closest on those numbers, published in full rather than folded into a score. Nothing here measures schools, crime, prices or what a place is like to be in, and a close match is a statistical fact rather than a suggestion to move.
