Federal and state law enforcement, academics and some media track mass shootings in the United States. But they use a variety of definitions for a mass shooting and they come up with different data sets.

Two findings they agree on: One, the United States is by far the world’s leader in mass shooting incidents, and, two, mass shootings account for just a sliver of all gun-related deaths in the United States.

Here’s a numerical look at recent U.S. mass shootings — including ones at spas in the Atlanta area and at a grocery store in Boulder, Colo., in March — in which four or more people were shot:

125 — Mass shootings through March 31, 2021, including the shooting in Orange, Calif., on Wednesday

614 — Mass shootings in all of 2020

190 — Fatalities so far in 2021

446 — Fatalities in 2020

408 — Injured in mass shootings so far in 2021

2,515 — Injuries in 2020

10 — Number of fatalities in most lethal incident so far this year (March 22, Boulder, Colo.)

7 — Number of fatalities in most lethal incidents of 2020 (March 15, Moncure, N.C.; June 4, Valhermoso, Ala.; Sept. 7, Aguanga, Calif.)
