San Marino is a small country located on the Italian Peninsula. It is completely surrounded by Italy and has an area of just 23 square miles (61 sq km) and a population of 31,817 people (July 2011 estimate).
San Marino, with a population of only 30,000 and a per capita income of $46,900, providing a basic service like education for free to its citizens would be a natural precedent.
Most visits to San Marino are trouble-free but you should be aware of the global risk of indiscriminate international terrorist attacks, which could be against civilian targets, including places frequented by foreigners.
