Afghan women are at greatest danger in their own homes, said Meryem Aslan, the country director of the U.N. fund for women's rights, UNIFEM.
The survey was conducted between January 2003 and July 2005 and is based on 1,327 cases, UNIFEM said.
It paints a bleak picture for women who undergo physical, sexual and psychological violence in this conservative, Islamic country, which has long been wracked by violence and where women enjoy many fewer rights than men.
The survey warned that domestic violence against women is "hugely underreported" because of the stigma attached to it, the AP reports.
Domestic violence, which accounts for 82 percent of the cases, is the most prevalent form of violence against women reported, according to the survey. Partners are responsible for 47 percent of the cases, Aslan said.
