Countryaah, San Marino has had a fairly stable population for a long
time, but in the last decades the population has grown,
mainly through immigration. There are about 4,000 foreigners
(mainly Italians) in the country, but in return a large
proportion of the citizens (just over 13,000) live outside
San Marino. The largest city is Serravalle (9,900 residents,
2012) followed by the capital San Marino (4,400 residents).
The official language and mother tongue of the population
is Italian. The traditional spoken language belongs to the
dialect group romagnolo.
