Since the massacre at Newtown, Conn., Slate has scoured the Web for information on gun-related deaths and adding them to this interactive. As the months unfolded, it became clear that even though thousands of people were being added to our database, we were missing thousands more. Now that we’re hitting the one-year mark, the full extent of that deviation is clear: The CDC counts about 32,000 people killed with guns each year, while Slate’s database only has one-third of that. Why the huge discrepancy?
Earlier this month Slate launched an effort to categorize the gun deaths in our system. That effort verified the source of the discrepancy: suicides.
