In this master's thesis, the author seeks to understand the determinants of attitudes on Intimate Partner Violence (IPV). She does this by correlating data on socioeconomic status, age, and education against survey data about IPV attitudes from Demographic and Health Surveys that were conducted in 56 countries across the world. Additionally, for purposes of analysis, she also ran correlations between attitudes and ancestral plow use data some the Ethnographic Atlas as a proxy for the presence of patriarchal norms. Finally, and most uniquely, the author conducted relational analyses between couples in order to gauge how IPV attitudes were influenced by the attitudes of a person's partner. The author concludes with suggestions of how this information can be used by policymakers in order to reduced and ultimately eliminate IPV.
