Unfortunately, I can't get to the StatCanada report that is cited here. But among the Canadian aboroginal population, there is higher reporting of spousal abuse. Maybe it's the same among Greek-Canadians, not sure, can't get to the report. Maybe you can?
http://www.statcan.ca/english/freepub/85-224-XIE/free.htm WHAT FACTORS CONTRIBUTE TO SPOUSAL ABUSE?
There is no single, definitive "cause" of spousal abuse, and anyone - regardless of gender, age, race, ethnicity, education, cultural identity, socioeconomic status, occupation, religion, sexual orientation, physical or mental abilities or personality - may be vulnerable to being abused. Spousal abuse is a complex problem, and there are may be many different contributing factors - at the individual, relationship and societal level. Many experts, however, believe that spousal abuse is linked to inequalities among people in our society and to power imbalances in relationships.
There is increasing understanding recognition that a person's vulnerability to abuse may be increased by factors such as dislocation,13 colonization,14 racism, homophobia, disability, poverty, and isolation.15 Aboriginal women, for example, are more likely to report being abused by a spouse.16
Lack of access to community services and supports, and to the criminal justice system, may further increase a person's vulnerability to being abused - or compound the effects of the abuse.
Factors that increase risk
Although they are not direct causes of abuse, recent statistics indicate that there are a number of factors that, alone or in combination, are associated with an increased risk of abuse. For example, some of the risk factors,17 for both men and women, include:
being a young person
living in a common law relationship
having a partner who periodically drinks heavily
emotional abuse in the relationship (an important predictor of physical violence, and
marital separation (women's risk of being killed increases after separation).
No statistical information is available at this time about factors that are associated with an increased risk of abuse for individuals in same-sex relationships.
