There have been, on average, 10 mass shootings in the U.S. each week this year

When a man walked into a birthday party in Colorado Springs, Colo., over the weekend, killing six people and then himself, it was the deadliest mass shooting in the state since March, when a rampage at a grocery store left 10 people dead.

We're just 18 weeks into 2021, and already the U.S. has experienced 194 mass shootings. That averages out to about 10 a week.

The tally comes from the Gun Violence Archive, which defines a mass shooting as an incident in which four or more people are shot or killed, excluding the shooter. The full list can be found here.

While a rise in gun sales and divergence of some public health funding could be linked to the spike in gun violence in recent months, experts say it can be a challenge to isolate any single cause. And advocates against gun violence lament the limited legislative response from Washington so far.

Here are the 11 attacks that took place just this weekend alone:
