There is no definitive answer to this question as it largely depends on the definition of "domestic violence" and how it is measured. However, based on a variety of studies and reports, it is generally agreed that the highest rates of domestic violence are found in developing countries and among certain ethnic and socio-economic groups. In terms of specific countries, rates of domestic violence are believed to be highest in Africa, the Middle East, and South Asia. In terms of specific groups, domestic violence is believed to be most common among women who are poor, uneducated, and belong to lower castes or ethnic minorities.
