Annual Global Survey Mini Report 1: Gender


The WFH Annual Global Survey (AGS) mini reports are advocacy tools that provide more in-depth perspective and context to AGS data. Lack of diagnosis and treatment for women and girls with bleeding disorders remains a challenge in our community. Highlighting gender data from the AGS can help bring awareness to the issues facing women and girls.
