Grey eyes are relatively rare, accounting for less than 1% of the world’s population. While it’s difficult to pinpoint which nationality has the most grey eyes, some regions have a higher incidence of grey eyes than others.
Grey eyes are typically found in people of European descent. The distribution of grey eyes in Europe is quite diverse, with certain regions having a higher incidence of grey-eyed individuals than others. For example, Ireland has a relatively high percentage of people with grey eyes, estimated to be around 30% of the population. Other countries with a high percentage of grey-eyed individuals include Scotland, Germany, and Iceland.
In general, countries in Northern and Central Europe have a higher incidence of grey eyes than those in Southern Europe. This is likely due to the fact that the genes responsible for grey eyes are more prevalent in people of Northern European ancestry. The same genes that produce grey eyes are also responsible for producing blue and green eyes, which are more common in Northern and Central Europe.
It’s also worth noting that the prevalence of grey eyes has changed over time. For example, in the United States, the incidence of grey eyes has decreased over the past century. This is likely due to the fact that the country has become more diverse, with more people of non-European ancestry. As a result, the genetic pool has become more mixed, leading to a decrease in the prevalence of certain traits, including grey eyes.
Overall, while it’s difficult to pinpoint which nationality has the most grey eyes, it’s clear that grey eyes are most commonly found in people of European descent, particularly in Northern and Central Europe. While grey eyes are relatively rare, they are also highly sought after for their unique and striking appearance.
