Infrastructure refers to all public and private facilities which are considered to be necessary for adequate public services and economic development. In most cases, the infrastructure is divided into technical infrastructure (e.g. transport and communications facilities, energy and water supply or wastewater disposal) and social infrastructure (e.g. schools, hospitals, shopping or cultural facilities).1

1 The definition of social infrastructure can vary as described in the social infrastructure entry which is divided into physical social infrastructure and institutional social infrastructure.
