The Public Distribution System (PDS) is a government initiative in many countries, including India, aimed at providing essential commodities like food grains, sugar, and cooking oil to low-income families at subsidized prices. This system helps ensure food security and supports vulnerable populations by making basic necessities more affordable. Under the PDS, eligible households receive ration cards, which allow them to purchase goods from designated fair price shops. The system is designed to reduce poverty and improve nutrition by making essential items accessible to those in need, thereby promoting overall social welfare.
