  • The Output Area Classification

    The Output Area Classification (OAC) distills key results from the Census for the whole of the UK to indicate the character of local areas.

    It profiles populations, structures other data, and helps target resources. OAC is in the public domain, and the User Group supports and promotes its use as geodemography open to all.
