The City Development Index (CDI) was developed for the Second United Nations Conference on Human Settlements (Habitat II) in 1996 and measures the level of development in cities. The United Nations Human Settlements Programme (UN-Habitat) used the indicator to rank cities of the world according to their level of development. The CDI is based on five sub indices: infrastructure, waste, health, education and city product. It was invented by Dr Joe Flood, first Coordinator of the Urban Indicators Program, following a statistical analysis of city indicators data.
