Despite past rumors of ending, the system still exists. As of 2012, a coupon book taken to a ration shop provided family minimums for rice, sugar, matches, and oil, above the average wage of $30/month. While most Cubans do not have to pay for rent, healthcare, or education, ration fees often take up a large percentage of their monthly income, and the unsubsidized costs of their monthly rations would be greater than the average monthly income. The amount of food provided to each citizen has decreased somewhat over time due to the end of billions in yearly financial support from the USSR and increased sanctions from the United States, and there have been significant increases in the ration fees at times.
