This report explores the distribution of household wealth in the EU Member States and analyses the role of wealth in social mobility. Using data from three datasets (the Household Finance and Consumption Survey, the Survey of Health, Ageing and Retirement in Europe and the Luxembourg Wealth Study), it focuses on wealth per household member. Wealth composition is compared across social groups and countries, and the role of housing assets in wealth distribution and negative wealth is assessed. The findings show that parental background, including parental wealth, has an impact on educational and wealth mobility. In order to promote equality of opportunities in terms of access to education and housing, the impact of wealth inequalities, including differences in parental wealth, should be counterbalanced. The report also suggests that regularising wealth declaration in the EU could be a way of promoting social justice by minimising hidden wealth and combating tax evasion.
