Violence against women and girls (VAWG) is a significant social, economic and public health problem. No country is immune from this problem and it impacts all socio-economic groups, all ethnicities  and all ages. This does not mean it is inevitable; it can be transformed through political will, through increased investment in programmes and policies, and through community support for normative change. The publication has been authored by the Members of Component Two for What Works: Economic and Social Costs of Violence Programme.
