The Center for Global Development, a non-profit think-tank in Washington DC, created the Commitment to Development Index which ranks and evaluates the achievements of DAC countries to the developing world. It measures the "development-friendliness" of the donor nations, moving beyond standard comparisons of Official Development Assistance. The Index quantifies a wide range of policies on seven indicators: aid, trade, investment, migration, environment, security, and technology. In 2009, Sweden and Denmark received the highest rankings, while Japan and South Korea fell toward the bottom.
