This document introduces the concept of development as freedom. It argues that development should be viewed as expanding the real freedoms that people enjoy, rather than narrow views focused on economic growth. Freedom depends on factors like education, health care, political rights, and economic opportunities. Poverty and lack of opportunities can severely limit freedoms. An approach focusing on expanding substantive freedoms integrates economic, social, and political considerations in analyzing development. It illustrates how different types of freedoms are interconnected and influence each other.
