A critical examination of how differences in gender roles, activities, needs, opportunities and rights/entitlements affect men, women, girls and boys in certain situations or contexts. Gender analysis examines the relationships between females and males and their access to and control of resources and the constraints they face relative to each other. A gender analysis should be integrated into the humanitarian needs assessment and in all sector assessments or situational analyses to ensure that gender-based injustices and inequalities are not exacerbated by humanitarian interventions, and that when possible, greater equality and justice in gender relations are promoted.
