Violence against women and girls (VAWG) is widely recognised as a violation of human rights and a challenge to public health. Further, VAWG is an under-examined, but crucial component of the overall crisis in South Sudan. VAWG has economic and social costs that have not been adequately recognised either in South Sudan or internationally. These costs not only impact individual women and their families but also ripple through society and the economy at large. The impacts of VAWG on economic development has not been adequately investigated, analysed or quantified in South Sudan.
