It's estimated that less than 2 percent of the world's population has naturally red hair.
Given the current world population is approximately 8 billion people, this translates to roughly 160 million redheads worldwide. While around 4-5% of people carry the gene for red hair, not all carriers express it.
Here's a breakdown:
- World Population (approximate): 8,000,000,000
- Percentage of Redheads: Less than 2%
- Estimated Number of Redheads: 8,000,000,000 * 0.02 = 160,000,000
Keep in mind this is an estimate, and the actual number could vary. Regional concentrations of redheads are higher in areas like Scotland and Ireland.
