As of my last knowledge update in October 2023, there isn't a specific global percentage of men actively participating in efforts for gender equality that is universally accepted or tracked. Various studies and surveys may report different figures based on criteria such as awareness, advocacy involvement, or attitudes toward gender equality.
For example, some surveys may indicate that a certain percentage of men believe in gender equality or support women's rights, while others might focus on men who engage in activism or educational efforts. These numbers can vary significantly by region, culture, demographics, and the specific metrics being measured.
If you're interested in recent statistics or studies, I’d recommend checking resources such as the World Economic Forum's Global Gender Gap Report or research from organizations focused on gender studies and equality, as they often conduct relevant surveys and publish findings on men's roles in promoting gender equality.
