Intimate partner violence (IPV) is a widespread issue, particularly affecting married women in low- and middle-income countries (LMICs), where cultural norms often lead to its acceptance. Using data from national demographic and health surveys and a two-level hierarchical model, this study examines factors affecting IPV acceptance among married women in 20 LMICs. Studies show that higher education, greater wealth, decision-making power, urban residency, and older age at marriage all reduce IPV acceptance. Furthermore, surveys from 2019 to 2022 indicate a decline in acceptance of IPV. In LMICs, targeted interventions need to be implemented to reduce IPV and increase gender equality.
