Gun deaths are now the leading cause of death for US children and teenagers, overtaking car crashes, according to research released in April.
In 2020 - the last year for which complete figures are available - 4,300 young Americans died of firearms-related injuries.
According to the New England Journal of Medicine,
the overall rate of gun deaths of all kinds - including suicides, murders, and accidents - rose by 29.5%, twice that of the wider population.
Gun violence in the US has steadily increased since the Covid-19 pandemic began in early 2020.
