Rob,
I also looked into this and Skyscanner was the only place this statistic could be found. Skyscanner is a social media based app / travel web site and makes no claims to be a true research source. They only stat they had was based on a State Department stat of one assault on American women a month with a 7 year average of 78 total assaults in the time frame. USA Today went to the only place they could find to prop up their claim for the article. A better and real source would have been the International Women's Travel Center but neither they nor any other valid source I found had the stat reported in the article. Further research showed USA Today giving plenty of advice for having a great time in while traveling to Jamaica ..
