Michael Bloomberg is paying $10 million to run an ad focused on his gun-control advocacy during the Super Bowl. The ad makes the claim that "2,900 children die from gun violence every year" but about half that number appear to be adults.
The ad doesn't actually cite a source but the number matches this report from Bloomberg's Everytown for Gun Safety. Their stat includes 18 and 19-year-olds which appear to make up about 49% of the total deaths. everytownresearch.org/wp-content/upl…
Everytown's report is about gun violence involving "children & teens" but Bloomberg's ad uses the same stat while referring only to "children."
Everytown used a five year average of gun deaths between 0-19 years of age in the CDC's Web-based Injury Statistics Query and Reporting System (WISQARS) to come up with 2,887 gun deaths per year among that age group. 
When you look at the same data but remove the adults you get 1,499 gun deaths per year among children between 2013 and 2017. That's about 51% of the number shown in Bloomberg's Super Bowl ad. webappa.cdc.gov/sasweb/ncipc/m…
You should all follow @kakutani_y, by the way. He helped me look at the CDC data and he's doing some fantastic reporting at the Free Beacon!
