The United States accounts for less than 5 percent of the global population, but owns 46 percent of the world's existing firearms, the report said, adding that the problem "fuels divisions and political polarization," Xinhua reported.
The impact on children is "especially concerning," it said, noting that 2020 saw more children lost their lives to guns than traffic accidents, which had previously been the main cause of death in this age group, and 2021 has seen the same pattern.
More than 20,700 people have died due to gun violence across the United States so far this year, according to the latest data from the nonprofit organization Gun Violence Archive.
