Monaco is the country with the highest median age in the world. The population has a median age of around 56 years, which is around six years more than in Japan and Saint Pierre and Miquelon – the other countries that make up the top three. Southern European countries make up a large part of the top 20, with Italy, Slovenia, Greece, San Marino, Andorra, and Croatia all making the list. Low infant mortality means higher life expectancy Monaco and Japan also have the lowest infant mortality rates in the world, which contributes to the calculation of a higher life expectancy because fewer people are dying in the first years of life. Indeed, many of the nations with a high median age also feature on the list of countries with the highest average life expectancy, such as San Marino, Japan, Italy, and Lichtenstein. Demographics of islands and small countries Many smaller countries and island nations have populations with a high median age, such as Guernsey and the Isle of Man, which are both island territories within the British Isles. An explanation for this could be that younger people leave to seek work or education opportunities, while others choose to relocate there for retirement.

In 2024, Japan was estimated to have the highest median age of the G7 countries at 49.4 years. Italy followed behind with 47.9 years. On the other hand, the United States had the lowest at just 38.3. Germany had an increasing median age until 2016, before the curve started to flatten. This is because of the increased number of immigrants arriving in the country at the time, particularly in the aftermath of the Syrian Civil War.

In 2024, Italy was the European country with the oldest population, recording a median age of 48.7 years, closely ahead of Bulgaria and Portugal, with 47 years.
