Seventy-seven percent of women and 34 percent of men said they had encountered verbal sexual harassment. Fifty-one percent of women and 17 percent of men reported unwelcome sexual touching. Forty-one percent of women and 22 percent of men said they were sexually harassed online. A third of women and one in 10 men reported being physically followed, while 30 percent of women and 12 percent of men experienced genital flashing. Twenty-seven percent of women and 7 percent of men reported sexual assaults.

The survey deliberately included street harassment as well as other forms of abuse, Ms. Kearl said. “Sexual harassment is a human rights violation — whether it takes place on the sidewalk of a street or in an executive board room — because it can cause emotional harm and limit and change harassed persons’ lives,” she said.

The survey’s authors and sponsors say the results suggest that sexual harassment is more pervasive than people realize.
