Abstract
Reducing inequalities in health is a global priority. An essential tool in achieving this reduction is the ability to provide valid measurements of inequalities, which are comparable over time and ultimately across countries and continents. With valid data a true understanding of inequalities can be ascertained, which can begin to inform effective legislation and policy. In this workshop, the speakers described in three different countries, Scotland, New Zealand and the Netherlands, how record linkage has been used to link ethnic status to health and health care measures and so to determine ethnic inequalities in health with the ultimate aim of reducing these inequalities.
