Combined, the eight Goals constitute a global compact between poor and rich to work today toward their mutual interests to secure a prosperous future. Mirroring past domestic efforts at social integration during their own economic development, industrial countries have in effect agreed to extend those policies and promises to poor people in poor countries. The CGD/Foreign Policy Magazine "Commitment to Development Index" measures and monitors the policies of rich countries that affect the poor. It provides one mechanism to ensure that rich countries, like the developing countries, are held accountable for their promises by their own citizens and the citizens of the world.
