The Commitment to Development Index focuses policies that benefit people living in poorer nations. It ranks 27 of the world’s richest countries (for the period 2003-2018) on these policies. The Index comprises seven components: aid (both quantity, as a share of gross national income, and quality), trade, finance, migration, environment, security, and technology. Each component is underpinned by a series of indicators of policy effectiveness in these areas. A country receives points for policies and actions that support poor nations in their efforts to build prosperity, good government, and security. The scores across these seven components are averaged for a final score. The migration component related to migration policy is composed of: 1) an indicator on international conventions 2) indicator on integration policies taken from the Migrant Integration Policy Index (MIPEX), developed by the Migration Policy Group (MPG). The indicator on international conventions assesses the extent to which countries have ratified international conventions aiming to protect migrants. Three conventions are considered: 1949 Convention concerning Migration for Employment (No. 97); 1975 Convention concerning Migrations in Abusive Conditions and the Promotion of Equality of Opportunity and Treatment of Migrant Workers (No. 143); 2000 Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children.
