San Marino, one of the world’s smallest and oldest republics, has experienced steady but modest population growth over the past seven decades. In 1950, the country’s population stood at just 13,000, and by 2024, it has grown to around 34,000. While small in absolute numbers, this growth reflects San Marino’s gradual urban development, improved healthcare, and stable economy.
Historical Population Growth (1950–2024)
San Marino’s population has expanded slowly but consistently over the past century.
- In the 1950s, the population averaged around 13,000–15,000.
- By the 1970s, the number had grown to 18,000–19,000.
- The 1980s and 1990s saw steady increases, reaching around 24,000–26,000.
- By 2010, San Marino surpassed 31,000 residents.
- In 2024, the population is estimated at 34,000.
This slow growth rate is typical of small European microstates, where migration and natural increase play balanced roles in shaping demographics.
Future Population Projections for San Marino (2025–2100)
Looking ahead, San Marino’s population is expected to remain relatively stable throughout the 21st century.
- Projections indicate the population will remain near 34,000 until mid-century.
- After 2050, a slight decline is expected, with the population averaging 31,000–33,000.
- By 2100, San Marino’s population is forecast to stabilize at around 31,000.
This stability suggests San Marino will avoid the sharp demographic declines expected in some European nations, though an aging population may present future social and economic challenges.
