* Hair color distribution varies greatly across the world. For example, blonde hair is more common in Northern Europe, while brunette hair is more common in Southern Europe and other regions.
* There's no universal definition of "blonde" or "brunette." What one person considers blonde, another might call light brown, and the same goes for brunette.
* Hair color can change over time. People's hair can get lighter or darker with age, or they can choose to dye their hair.
Therefore, any attempt to answer this question would be highly speculative and likely inaccurate.
