We put together the different conceptual issues involved in measuring inequality of opportunity, discuss how these concepts have been translated into computable measures, and point out the problems and choices researchers face when implementing these measures. Our analysis identifies and suggests several new possibilities to measure inequality of opportunity. The relevance of the conceptual issues and modelling choices are illustrated with findings from the empirical literature on income inequality of opportunity.
