Evidence shows that Guinean women and girls face important barriers across all dimensions of well-being that prevent them from having access to opportunities on an equal footing with men. The poor agency of women and girls, as reflected in the high prevalence of discriminatory legal and social norms, translates into gaps in health, education, employment, and entrepreneurship, ultimately undermining their capacity to fulfill their potential and imposing important societal costs. This report presents a summary of the key challenges facing Guinean women and girls relative to men and boys. The report has a particular focus on early family formation, a common phenomenon in the country with important implications for girls' and women's well-being and opportunities in life. On the basis of this diagnostic and a review of evidence of what works, the report proposes some strategic lines of action to address the existing constraints and effectively empower Guinean women.
