The Sutherland Springs, Texas, church shooting on Sunday killed about 4 percent of the small town’s population.

That estimate comes from CNN, showing just how much of a gruesome impact the single shooting had on the small unincorporated community of about 600.

The ages of the deceased range from 18 months to 77 years, a Texas Department of Safety official said. They include First Baptist Church Pastor Frank Pomeroy’s 14-year-old daughter and all of his family’s close friends, Pomeroy told Houston-based ABC13.

In total, about 7 percent of the town was shot in the massacre.

The incredibly high percentage is in part a reflection of the town’s size, making it so just one event can have an outsize impact.

It also means, however, that a lot of people in the town know the victims. As a resident told a local CBS affiliate, “One of the guys lives down the street. I see him all the time. I wave at him and stuff every time he drives by. The people at the church, I see them, I wave at them all the time. They always do their Thursday night things. They know me as the neighborhood blacksmith.”
