While the health of Europeans has improved over recent years, differences by gender, birthplace, and/or socioeconomic background persist. This report maps the extent of such health inequalities, its determinants, and costs to society. The findings indicate that differences in health between and within countries are attributable not only to social and health policies, but also depend on economic policy and the social determinants of health. Thus, holistic policy interventions are required to tackle health inequalities.
