For a place often associated with growth and glamour, Monaco is entering a more nuanced chapter. According to the latest report from IMSEE, 2025 marked the first time in over three decades that deaths outnumbered births among Monegasque nationals—a subtle but telling shift in the Principality’s demographic story.
The figures themselves are modest, yet significant. Eighty-four births were recorded last year, compared to ninety-three deaths, pushing the natural balance into negative territory for the first time since the early 1990s. Behind this change lies a broader trend: fewer births, paired with a steadily aging population.
And yet, Monaco continues to grow. As of December 31, 2025, the number of Monegasque citizens reached 9,959, edging closer to the symbolic 10,000 mark. This increase is not driven by births, but by new citizens—through marriage and naturalization—highlighting how the Principality’s identity is gradually evolving.
The population itself reflects this shift. Women account for just over half of all nationals, and the average age now stands at 45.3 years. Longevity, in particular, is striking. Life expectancy has climbed to a record 88.5 years, placing Monaco among the highest globally. It’s a sign of both quality of life and long-term stability—but it also reshapes the population pyramid.
Elsewhere, there are signs of renewal. Marriages rebounded in 2025 after a quieter previous year, suggesting a return to more typical social rhythms following recent legislative changes.
Taken together, these figures sketch a portrait of Monaco that is less about rapid expansion and more about balance. Growth continues, but through different channels. Beneath the surface, the Principality is adjusting—quietly, steadily—to the realities of time.
