OAs are the smallest
unit of UK Census geography and have an average household
population of 117 individuals. Carstairs deprivation scores
were derived from raw Census data,
for the whole of Scotland, at the OA level. Carstairs scores provide
a summary measure of areas’ relative deprivation, comprising an
unweighted combination of four standardised Census indicators:
male unemployment, overcrowding, lack of car ownership and
low social class.
