Rationing in Cuba refers to the system of food distribution known in Cuba as the "Libreta de Abastecimiento" ("Supplies booklet"). The system establishes the amounts of subsidized rations each person is allowed to receive through the system, and the frequency at which supplies can be obtained. While the food rations are not free, the ration fees are a small fraction of the actual price of the goods (on average, less than $2 USD for a month of rations, which is approximately 12% of their market value). Purchases of the goods can also be made outside of the system, but they are typically too expensive for most Cubans to afford.
