ENThis paper proposes an assessment of the association between income and unmet health needs in 29 European countries included in the European Health Interview Survey (EHIS) in 2015. Income-related inequalities for four categories of unmet needs are estimated by the Erreygers Index (EI). Unmet needs are organised into two categories: on the one side, unmet needs directly associated with households’ budget constraints; on the other side, unmet needs not directly associated with budget constraints, as waiting lists and transportation problems. Results show that all categories of unmet needs fall on lower-income people for most European systems. Furthermore, when analysing the determinants of unmet needs, those directly associated with budget constraints are led by the economic drivers, while income-related unmet needs due to long waiting lists and distance or transportation problems are more related to institutional factors such as the low quality of government. Keywords: Unmet health needs; Income-related inequality; European union.
