Figures are the latest available in GeoNames (CC BY 4.0), which draws on national censuses of varying dates — treat them as recent, not same-year. Country totals are UN World Population Prospects 2024 (medium variant) where the UN lists the country separately; the handful it reports under a parent state keep a GeoNames figure and are marked as such. Sources & method.
Treat these figures with care. The settlements listed below sum to 49,949, against a national population of 33,605. Some overlap is normal where towns run together, but a gap this wide suggests the underlying figures for San Marino are unreliable, and we have not been able to verify them independently.
