The Commitment to Development Index ranks 27 of the world’s richest countries (OECD countries) on policies that affect the more than five billion people living in poorer nations.

Its objective is to assess the extent to which the migration policies of the countries of the OECD are 'development-friendly'. This assessment is combined with estimations of the extent to which six other policies (aid, trade, finance, environment, security, and technology) reflect a commitment to development, in order to create an overall 'commitment to development index'. The hope is that this will put pressure on developed country governments to try to increase their placing in the ranking vis-à-vis other OECD countries.
