“In a recent study of 24 developing countries that I conducted with my colleagues, Jennifer Bleck of the University of South Florida and Amber Peterman of the University of North Carolina at Chapel Hill, we found that a combined total of only 7 percent of survivors of gender-based violence (physical and sexual, perpetrated by anyone, including intimate partners) formally reported the violence to police, medical, or social services—combined.
But in India, less than 1 percent of survivors reported gender-based violence to formal sources. This was the lowest percentage among all of the countries we studied. The highest was Colombia, with 26 percent.
This means that even in Colombia, 3 in 4 women who experienced gender-based violence did not formally report the attack. And while there was a wide variation between the countries in each region, those areas where women were more likely to report gender-based violence to formal sources included Latin America and the Caribbean and Eastern Europe/Central Asia, compared to India/East Asia and Africa.
We also looked at whether women told their family, friends, and neighbors (we called this “informal reporting”) about the attack, and found that rates of informal reporting ranged from 15 percent in Honduras to 60 percent in Ukraine. In fact, in 20 of the 24 countries studied, the majority of women told no one at all. This means not only that most survivors are not receiving formal services, but that they are not even receiving informal support from friends and family members to deal with the violence they have experienced.”
