It discusses the interdependence of sectors, the rising importance of the service (tertiary) sector, and the formal and informal sectors. It also differentiates between organized and unorganized sectors and explains how employment and GDP contributions vary across sectors. The concept of underemployment is explored, and the chapter highlights the role of the government in providing employment and social security measures.
