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.

Click to see the interactive, crowdsourced map visualizing reported gun deaths since Newtown, from Slate.

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

Number of people killed by guns so far in 2014: 4,772

Estimated real number of people killed by guns, including homicide, suicide and accidental death since Newtown (using most recent CDC estimates for yearly data): 51,158

Total gun deaths in 2010 (the latest year for which the CDC posts data): 31,672
number of those who were children or teens: 2,700

Number of school shootings since Newtown: 79*

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 Vote

On April 17th, 2013, the Senate defeated several gun control measures, including the overwhelmingly popular proposal to expand background checks for firearms purchases. Here’s how each senator voted on the bipartisan proposal by Joe Manchin (D-WV) and Patrick J. Toomey (R-PA) that would have expanded background checks to online sales and sales at gun shows. The measure needed 60 votes to pass.

Yes Votes (54)

No Votes (46)

*Reid voted no for procedural reasons.

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.
