Thats usually how the data is seen. Socio economic status correlates to violence against women. Sometimes landed "gentry" are also prone to it, when power issues are at play. In Anglo-Indian writings for instance, the rape of Indian women by white men was common under colonialism, the instances of rape of white women by Indian men became common in literature after the mutiny.
The power over women is a frequent corollary in colonial writings [where settlers come to "virgin" lands, for instance and "save" them from their pagan overlords]. You can see the same theme in current wars, where everyone is saving women by massacring their families. Note that the women saved generally only live in the countries already invaded, under occupation or about to be invaded. Womens rights in allied countries have very little need for review. Note that you never actually see, hear or know the opinions of these liberated women, since they are not really important enough to get media time, unless they have been disfigured by the enemy
The ones disfigured by allies are of course, all collateral damages .
