Around 80% of redheads are found in Celtic nations, such as Scotland and Ireland

Statistic 40

Redheads represent a higher percentage of the population in Ireland (about 10%) than in other countries

Statistic 41

Red hair is most common among Northern European populations, especially among the Scottish and Irish

Statistic 42

Red hair and fair skin phenotype is most common in people of Celtic descent, especially Irish and Scottish

Statistic 43

The rarest natural hair color is red, with only about 1-2% of the global population

Statistic 44

Despite being a minority, redheads have a noticeable presence in popular culture, often portrayed as fiery or unique characters

Statistic 45

The red hair trait appears in diverse populations globally, but is most prevalent in Northern and Western Europe
