Global Health 50/50 is an independent, evidence-driven initiative to advance action and accountability for gender equality in global health at The UCL Centre for Gender and Global Health. The collective and its work can only be a success when global health policy and organizational decision-making puts a gender lens, gender equality, and health equity at the core of all it does. For decades, its collective members have researched, advised, advocated for, published, and delivered policies and programs to promote gender equality and health equity.
