This report examines the review-level evidence that is available to guide action on reducing socioeconomic inequalities in health. Evidence about public health interventions, programmes and policies applied to populations, groups and other geographically defined areas or jurisdictions was sought to explore whether they preferentially improve the health outcomes of people experiencing socioeconomic inequalities. We identified 17 umbrella reviews, 106 systematic reviews and 30 other types of reviews that had an equity focus and had been published since 2000. Twelve umbrella reviews and 54 reviews were categorised as examining the wider social determinants of health. Seven umbrella reviews and 79 reviews were categorised as examining the behavioural determinants of health.
