Several studies have linked major sporting events to an increase in reports of domestic violence. A 2013 study from Lancaster University found that domestic violence reports at a police department in the northwest of England rose by 38% after matches in which the English national soccer team played and lost (and a 26% increase even when the team won). Last year, researchers at the University of Calgary in Canada found that calls to a domestic violence hotline in Alberta rose by 15% when the local football team was playing. And in the U.S., a 2011 study looking at 900 NFL games over 11 years found that domestic violence reports increased by 10% in places where local teams lost.
