Are there more male singers than female?

Both males and females have both the equipment and disposition to sing and so any disparity in numbers between them is a result of culture. In different places at different times male or female vocalists may be more popular and there will naturally be more of whichever is popular. One factor which inhibits males from singing in North America is the voice change which occurs in males between the ages of 10 and 20. Struggling with this problem often turns males away from singing and many do not come back to it after their voices settle. As a result there are a lot more amateur female choral singers.
