Core Principles & Analysis

• Mahbub ul Haq launched it with Amartya Sen's collaboration in the 1990 Human Development Report.
• Each dimension is normalized against fixed goalposts and the three are averaged geometrically.
• It deliberately ranks health and education alongside income, reshaping the development debate.
