Mass shootings have happened almost every day in America this year — often more than once a day. They happen in backyards and at block parties, in mansions and housing projects, in quiet neighborhoods and at rowdy bars, at schools, restaurants, churches, gas stations and grocery stores. They are random, and they are premeditated. They happen during dice games, family dinners, funerals and sweet sixteens.

So far this year there have been 353 mass shootings in the United States, according the Mass Shooting Tracker, a crowd-sourced database. (The tracker defines a mass shooting as one in which at least four people are killed or wounded; the FBI uses three dead or wounded as its criteria.)

Here they all are, including Wednesday’s attack in San Bernardino — the deadliest shooting in the U.S. since Sandy Hook.
