The SAHRU deprivation index was originally developed in 1997 to be similar in design to the widely regarded Carstairs and Townsend indices employed in the UK, with certain modifications in view of differences in definition and scope between census variables in the UK and Ireland. The SAHRU index has been used widely in health and health services research in Ireland. This report updates the former SAHRU Deprivation Index using the outputs of the 2016 Census. The data are also presented for the 2006 and 2011 SAHRU indices, along with an exploratory analysis of changes over time.
