Gender-based violence (GBV) is a global issue that robs people of their basic right to safety and security. While GBV can affect anyone, it disproportionately affects women and girls. In many communities worldwide, GBV is a pervasive social problem, driven by cultural norms and patriarchal attitudes. To tackle GBV effectively, it is essential to understand its nature and extent in different communities. Data-driven approaches play a critical role in exposing GBV, identifying patterns, and developing evidence-based policies and interventions. This blog explores how data can help expose GBV in different communities, leading to better policy and intervention outcomes.
