National development is the process of reconstructing and developing a nation across various dimensions to improve citizens' welfare. It involves the full growth of industries, agriculture, infrastructure like education and healthcare, and the application of science and technology. Key indicators of national development include GDP, per capita income, literacy rates, life expectancy, and infant mortality. In India, the National Development Council is responsible for planning and overseeing development. However, India faces ongoing challenges to development from issues like uneven education and skills, rapid urbanization, health and sanitation problems, gender discrimination, corruption, and the need for overall economic growth.
