Other media outlets have reported that hundreds of mass shootings take place in the United States in a single calendar year, citing a crowd-funded website known as Shooting Tracker which defines a mass shooting as having four or more people injured or killed.[122] In December 2015, The Washington Post reported that there had been 355 mass shootings in the United States so far that year.[123] In August 2015, The Washington Post reported that the United States was averaging one mass shooting per day.[124] An earlier report had indicated that in 2015 alone, there had been 294 mass shootings that killed or injured 1,464 people.[125] However, an article from Russia Today stated that 42 percent of the incidents involved zero deaths, and 29 percent one death.[126] Shooting Tracker and Mass Shooting Tracker, the two sites that the media have been citing, have been criticized for using a criterion much more inclusive than that used by the government—they count four victims injured as a mass shooting—thus producing much higher figures.[127][128]
