This study reports analyses and findings from a public opinion survey designed to explore beliefs about domestic violence (DV) -- what it is, when it is against the law, and how prevalent it is. The project interviewed 1,200 residents from six New York communities. The analyses reveal substantial first hand and second hand experience with DV and strong consensus that acts of physical aggression should be labeled as DV, but substantially less certainty about the illegality of the abusive behaviors. Overall, the respondents were less inclined to define women's aggressive behavior in pejorative or unlawful terms than men's. Respondents believed that DV was common in their communities, and that it affected a significant minority of couples. Multivariate analyses provide little support for conventional wisdom about the impact of socioeconomic background on tolerance for or knowledge about DV, although gender, generation, and secondhand familiarity with DV incidents play a role in opinions and beliefs.
