Conversely, in Italy and Ireland, severe material deprivation increased at the same rate for the most deprived regions (Sicily in Italy, Midland and Western region in Ireland) and for the country as a whole.10 These severe material deprivation rates calculated at regional level are highly correlated with the relative income poverty headcounts in some countries (in Italy, in particular), while the correlation is not statistically significant in others (e.g. Spain). Statistics to monitor multiple dimensions of material deprivation have been developed through a harmonized survey for Europe, but comparable data are rarely available for non-European OECD countries. A policy-relevant ranking of regional material deprivation can also be obtained through composite indicators.
