Firearm Injury & Policy Research Program

The Firearm Injury & Policy Research Program’s mission is to reduce the impact of firearm injury and death on people’s lives through interdisciplinary research and collaboration with institutional, community, and governmental partners.

HIPRC has a three decades-long history of studying firearm injuries, with researchers conducting pivotal studies on access to firearms in the home, safe firearm storage practices and promotion, and assessing lethal means availability for patients evaluated in emergency departments.

FIPRP formed in 2019 with funding from the Washington State Legislature.

Firearm Injury in Washington


The Giffords Law Center estimates the annual cost of gun violence to be $3.8 billion to the state and $544 for every Washington resident.1 In 2017, Washington State had 849 deaths attributed to firearms with a death rate of 11.1 per 100,000 population compared to a 12.0 rate for the United States as a whole.2 Seventy-six percent of firearm deaths in the state are attributed to suicides.1 Black men (aged 18 to 24) are 20 times more likely than white men to be firearm homicide victims.1 According to the Alliance for Gun Responsibility, US women are 16 times more likely to be firearm homicide victims than women in peer countries.3 Additionally, the second leading cause of death for children in the United States are firearms, which are also a major contributor to the homicide of LGBTQ+ identified individuals with approximately half being murdered by firearms.3


According to the Washington State Behavioral Risk Factor Surveillance System, between 2013 and 2016, 34.3% of households had a least one firearm, 36.6% of whom stored it locked and unloaded.4 Approximately, 18.8% of participants reported storing the firearm unlocked and loaded.4 A study of firearm ownership and storage in relation to suicide risk and memory loss among older adults in Washington State revealed that of the 4,428 study participants, 38.6% reported having a firearm in the home and 23.5% of these individuals stored at least one firearm unlocked and loaded.5 In this group, 17.4% had depression, 6.9% had frequent mental distress, and 12.2% had memory loss. This is particularly salient as there is an association between suicide and firearm ownership as well as higher rates of firearm death for adults aged 75 and older.6


Suicides comprise a large portion of firearm deaths in Washington and the country. Approximately 76.4% and 75.3% of firearm deaths in Washington in 2013 and 2017, respectively, were suicides compared to 63% and 60% in the United States.6 Suicide decedents were more likely to own at least one firearm arm.7 Additionally, suicide decedents were two to four times more likely to own a handgun, store a firearm loaded, or carry a firearm off-duty.7

Intimate Partner Violence

An additional risk factor for firearm injury and death includes intimate partner violence. Approximately 47% of intimate partner homicides in Washington involved a firearm, and in a multistate study about 61.2% of adolescent intimate partner homicides involved a firearm.1, 8 In a study on intimate partner homicide (IPH) among adolescents and youth adults, 90% of adolescent IPH victims were female and an average of 16 years old. The majority (77.9%) of the perpetrators were over 18 and 62.7% of them were current intimate partners of the decedents.8 Perpetrators of IPH against young adults (aged 19 to 24) were older and more likely a past intimate partner than those of adolescent IPHs.8 IPH was committed for a variety of reason, the most common of which were jealousy or broken/unrequited relationships and pregnancy related.8

Harborview Injury Prevention & Research Center

Regarding other original research, Firearm Injury & Research Policy Program researchers discovered a spatial disparity between where a firearm injury occurs and where it is recorded in police records, with the median distance being 3.9 miles.9 Additional recent research conducted through the Harborview Injury Prevention & Research Center include investigation of the relationship between state beer excise tax and firearm homicides;10 correlation between prior criminal history, substance use, and firearm injury;11 and relationship between income inequality and firearm homicide.12
