IMSEE stats for 2018

The year 2018 saw the lowest number of births in Monaco for the past 16 years, but it also recorded the lowest number of divorces in 30 years. These were just some of the interesting facts to have come out of the latest demographics study released this week by statistics body IMSEE.


As of 31st December, the Principality had 9,326 Monegasque nationals. This figure signals a slow-down in annual population growth, which had stabilized between 2014 and 2017 at + 1.1% on average, to + 0.7% in 2018.

Meanwhile, the average age of Monegasques is 44.3 years. Women are, however, generally six years older than men with one in two women at least 50 years old, whereas in men, the median age is 41 years old. Half of all Monegasques are aged over 46.7 years.

2018 also recorded a low birth rate, with 90 registered births and a Synthetic Fertility Rate of 1.9 children per woman, the lowest level since 2003. The average age of mothers at birth reached an all-time high of 33.1 years.

At the other end of the spectrum, 94 deaths were recorded for a mortality rate of 10.1%, the second highest for the decade 2010.

Life expectancy at birth has slowed in recent years, standing at an average of 85.7 years in 2016-2018, or 83.6 years for men and 87.9 years for women.

IMSEE revealed that there were 76 marriages involving at least one Monegasque husband last year. The marriage rate is 8.1% which is below the average observed since 2000 (9.5%). In 2018, the average age of singles at marriage was 33.4 years for men and 31.2 years for women.


The number of divorces in 2018 is not yet known, given the inherent delays in the legal procedures. But it was revealed that there were 33 divorces in 2017, representing a divorce rate of 3.6 %. This is the lowest rate observed in more than 30 years.
