Further work on our measure of disadvantage revealed an error in the generation of HESA measure deciles. Our output area files for England, Wales and Scotland contained statistics for higher level geographies (either local authorities, regions and/or countries), which had not been removed prior to the formation of the deciles.
HESA measure deciles have been recreated based on a total of 232,296 output areas (181,408 in England and Wales, 46,531 in Scotland and 4,537 in Northern Ireland). Around 1% of output areas changed from quintile 1 to a higher quintile or vice versa. Approximately 5% of output areas were affected when undertaking an analysis by decile. We have found the impact of this to be minimal and the conclusions of our research are not materially altered.
