What is the ratio of male to female mathematicians?

The ratio of male to female mathematicians varies significantly by region and academic level, but globally, men generally outnumber women in the field. In many countries, the ratio can be approximately 3:1 or even higher. While efforts are being made to encourage more female participation in mathematics, disparities still exist in educational and professional settings. Consequently, the representation of women in mathematics continues to be a subject of focus for equity and inclusion initiatives.
