Sexual and gender-based violence is a global problem with dire consequences on health, social and economic structures and sometimes results in death. The scourge of SGBC in Nigeria is very alarming, with daily reports in the news media. Recognizing the cotextual and situational variation of SGBV at national and sub-national levels and the associated risk factors are imperative to guide intervention design. In this context, UNFPA Nigeria commissioned this formative research to generate evidence that reflects the realities at national and lower administrative levels to inform the planning of integrated SGBV intervention programmes. With funding support from Global Affairs Canada (GAC), this study aims to fill the existing data gaps in SGBV in Nigeria through an initiative that started on 1st March 2018 to 30th September 2022. The goal of the project is to reduce the prevalence of sexual and gender-based violence, child, early, and forced marriage (CEFM), obstetric fistula, and female genital mutilation and create enabling environment for the treatment and care of survivors. The research design and implementation plan will provide providing evidence-based information to guide the accurate map toward addressing SGBV in Nigeria.
