Back in 1949, retired U.S. Army veteran Howard Unruh unleashed a hail of bullets in his Camden, New Jersey neighborhood, claiming the lives of 13 people, including a 2-year-old baby and two more kids under the age of 10.
Since that tragic incident, the United States has witnessed a staggering total of 33 mass shootings that caused at least 10 fatalities (excluding the perpetrators). What’s particularly alarming is that half of these horrifying events occurred within the past decade.

Among these 33 horrifying crimes, Texas saw 7, California 4, while Florida, Colorado, and New York each experienced 3.
However, the most devastating incident unfolded in Las Vegas, Nevada, when a 64-year-old Stephen Paddock unleashed a barrage of gunfire upon a crowd attending a music festival from his 32nd-floor hotel suite. This horrifying act claimed the lives of 60 individuals, with over 800 others sustaining injuries.
The Gun Violence Archive maintains a broader record of mass shootings, documenting over 560 incidents from January to October 2023 alone. This translates to an astonishing average of approximately 1.9 mass shootings per day.

The Centers for Disease Control and Prevention (CDC) has compiled data on Firearm Mortality by State, spanning from 2005 to 2021, the latest available year. During this period, gun-related deaths steadily increased each year, rising from 30,540 in 2005 to a staggering 48,645 in 2021—an alarming 59% surge.
For the year 2021, the most recent data available, Texas recorded 4,614 deaths caused by firearms, followed by California with 3,576 and Florida with 3,142. Georgia ranked fourth with 2,200 deaths, and Illinois came in fifth with 1,995.
However, when assessing the severity of this issue based on gun-related death rates, none of these states make it into the top 10 list.
Mississippi claims the highest gun-related death rate, with 962 deaths in 2021, despite having a population of roughly 2.9 million. This translates to a staggering 33.9 gun-related deaths per 100,000 people. Following closely behind are Louisiana at 29.1, New Mexico at 27.8, Alabama at 26.4, and Wyoming at 26.1.
