The document discusses various social issues related to development of cities and towns. It notes that engineering, economic, administrative, legal, political and social issues are interdependent. A key social issue is migration to cities, which is driven by lack of basic amenities and infrastructure for lower-income groups in rural areas. The document argues for an integrated managerial approach to address these issues, rather than separate solutions. It proposes policies like requiring planned accommodation for migrant workers and lower-income groups to slow uncontrolled migration to cities.
