Here’s a look at some stats on guns — the deaths and school shootings, America’s public opinion and the failed Congressional attempt to take action — in the wake of the massacre at Sandy Hook Elementary School in Newtown, Connecticut, that killed 27 people, including 20 children and the shooter.

The Victims

Slate editors note in the introduction to their crowdsourced map that attempts to visualize gun deaths in the US (pictured below), determining the actual number of gun deaths each year is “surprisingly hard.” That’s because as many as 60 percent of gun deaths are suicides that usually go unreported by the press.

Number of people killed by guns, including homicide, suicide and accidental death, between Newtown and December 2013 (that have been reported by the media): 12,042

Note on methodology: In the above list, we sought to give a conservative count. Some lists, like the one on Wikipedia and the one at Everytown For Gun Safety, include shootings that we do not. Our list includes incidents that happened wholly or partially on a school campus while students or staff were there. Our list does not include incidents of law enforcement officers responding with gunfire to a student with a non-firearm weapon, (e.g., if police shoot at a student who is threatening others with a knife). Our list also excludes murders and suicides that did not involve students or staff but occurred on campus while students and staff were not in the building.

The State Laws

Since Newtown, no fewer than 114 bills were signed into law at the state level, according to an article in Mother Jones. In 22 states, new laws were created to curb gun violence. In 29 states, new laws were enacted making it easier for people to own guns, carry guns in public places and make it more difficult for the government to track guns. See an analysis of gun laws in your state and how it compares to others.
