In the United States, it is estimated that 2-6% of the population has red hair. This would give the U.S. the largest population of redheads in the world, at 6 to 18 million, compared to approximately 650,000 in Scotland and 420,000 in Ireland.
Red or reddish-tinged hair is also found in other European populations particularly in the Nordic and Baltic countries as well as parts of the Netherlands, Spain, Belgium, France, Greece, Turkey, Portugal, Italy, Germany, Russia and South Slavic countries.
Because of migration from Europe from the 16th to the 21st centuries, red-haired humans are also found all around the world, such as in North America, South America, Australia, New Zealand, South Africa, Siberia, etc.
The Berber populations of Morocco and northern Algeria have occasional redheads. Red hair frequency is especially significant among the Kabyles from Algeria, where it reaches 4 percent. The Queen of Morocco, Lalla Salma wife of king Mohammed VI, has red hair. Abd ar-Rahman I also had red hair, his mother being a Christian Berber slave.
