We really need an intelligence test of sorts for many of the goombas posting on this forum.
First real statistic to consider would be the;
And if one were to look/check, you will see the USA is about 81 on the list of 183 shown here. Note also, the method of violent death is secondary to the total number or percentage of populatuion that is victim. Start by getting your priorities and perspectives correct folks!
But statistics can vary per source. consider what you see here on this scale'
List of countries by intentional homicide rate
As for the thread OP here, one needs to consider that most "children" deaths, those in age range from 1-19 years old, tend to be by handguns/pistols anmd the major source would be related to gang activity/conflicts.
Another case for conflicting statistics will be;
Countries with the Highest Total Gun Deaths (all causes) in 2019
where the USA is second on a list of the top 8 the number/rate of suicide versus homicide isn't factored here; but when looking at "rate", numbers per 100,000;
...
Nearly nine out of 10 people killed by gun violence in 2019 were men. The highest number of homicide deaths occurred among people 20-24 years old, while the highest number of gun-enabled suicides happened among those aged 55-59. Brazil recorded the world's highest number of total gun deaths from all causes combined, with 49,436 out of 250,227 worldwide. The United States has the second-highest number of gun deaths with 37,038.
That said, if one isolates the violent gun deaths and adjusts for population size by expressing the rate as the number of homicides per 100k people, the list changes significantly.
...
