Lower Layer Super Output Area

A Lower Layer Super Output Area is a GEOGRAPHIC AREA.

Lower Layer Super Output Areas (LSOA) are a geographic hierarchy designed to improve the reporting of small area statistics in England and Wales.

Lower Layer Super Output Areas are built from groups of contiguous Output Areas and have been automatically generated to be as consistent in population size as possible, and typically contain from four to six Output Areas. The Minimum population is 1000 and the mean is 1500.

There is a Lower Layer Super Output Area for each POSTCODE in England and Wales. The equivalent in Scotland is ‘Datazone’ and in Northern Ireland is ‘Super Output Area’. A pseudo code is available for the Channel Islands and the Isle of Man.

The Organisation Data Service publish files created on their behalf by the Office for National Statistics, which link POSTCODES to the Lower Layer Super Output Area.

See the Organisation Data Service pages on the NHS Digital website at: Complete Gridlink NHS Postcode for the NHS Postcode Directory User Guide.
