Gun violence against other persons is most common in poor urban areas and is frequently associated with gang violence, often involving male juveniles or young adult males. Although mass shootings are covered extensively in the media, mass shootings in the United States account for only a small fraction of gun-related deaths. School shootings are described as a "uniquely American crisis", according to "The Washington Post" in 2018. Children at U.S. schools have active shooter drills. According to "USA Today", in 2019 “about 95% of public schools now have students and teachers practice huddling in silence, hiding from an imaginary gunman.”
