In Sweden, 23% of young women and girls between 16-24 reports to have been abused at least one time by a current- or ex-partner. Youth intimate partner violence is a critical issue with great negative impact on both individuals and society if not prevented early. Women and girls are recognized as essential actors in the 2030 Agenda, and strengthening the rights women and girls is an important step for achieving gender equality. The Foundation 1000 Möjligheter is a youth centre working to address the issue of youth intimate partner violence through support of young victims of abuse as well as to acknowledge young perpetrators of violent acts. The aim of this thesis was to examine the Foundation 1000 Möjligheter and their project UngaRelationer.se and how their work affects the knowledge gap of youth intimate partner violence in Sweden. Another aim was to investigate the consequences of youth intimate partner violence on sustainable development. This was studied through five qualitative semi-structured interviews; two with the Foundation 1000 Möjligheter, two with volunteers of UngaRelationer.se, and one with an employee of the Swedish Gender Equality Agency. The results were analysed through a literature review of the field of violence against women, feminist social movements and the gender and development theory. This study discovered that the lack of knowledge of youth intimate partner violence among youth, parents and other adults’ in proximity to youth is a hindrance to further initiatives to ending the violence. The Foundation 1000 Möjligheter addresses the knowledge gap on youth intimate partner violence through educating youths and adults on factors and perspective that are essential to understand and recognize violence and abuse. The efforts of the women’s movement to raise the issue and push for policy change is fundamental in the case of both adult and youth intimate partner violence and further mobilization is needed. The health effects as consequences of youth intimate partner violence risk to exclude young women and girls from higher education, meaningful interactions and influential positions in society. As women and girls are important actors of change, these consequences pose a threat to sustainable development.
