“Since 2018, women in nearly every category of race, age, marital status, educ level, & income have increased their gun ownership. In most of these cases, women's % increases in firearm ownership exceeded those of men belonging to the same group, often by 50% or more.”🧪 @andrewmorral.bsky.social
2018, less than a quarter of gun owners were women (22 percent); by 2024, women made up nearly a third of all gun owners (32 percent).

The pandemic firearm purchasing spree saw women’s gun ownership rise by 35%. (Men’s didn’t.) Growth in women’s gun ownership was incredibly broad-based, across income levels, races, education, etc. But exclusively among Republican women, not Democrats. www.rand.org/pubs/comment...

I am one of those early career researchers (described at the end of this piece) whose work has been possible because of these projects. I’m grateful for the risk folks took to prioritize such investments. This is a huge loss.💔

These projects have been immensely important to me, and I'm sorry to see them come to an end. But so long as gun violence remains a leading cause of death and grief in this country RAND will work to bring evidence and policy solutions to address it. www.thetrace.org/2026/02/rand...

The methods are pretty interesting, and I think useful for thinking through what covariates may be important to control for in gun policy analysis. We wrote them up here (and thanks to my coauthors, Greg Midgette and Terry Schell!). www.rand.org/pubs/tools/T...

Firearm Mortality and State Characteristics
Rates of homicide, death by suicide, and firearm violence vary dramatically among U.S. states. This tool allows users to investigate how these differences correspond with state characteristics.

Andrew Morral @andrewmorral.bsky.social · 06/02/2026
Example: How much do demographics correlate with state firearm suicide rates? FL, MT, AK, WY and other states have MUCH higher firearm suicide rates than other states with similar demographics. Whereas SD, CA, NC and others have much lower rates than states with similar demographics.

A state legislator once told me the ’”only reason” his state had such a high suicide rate was because of its large Native American population. This tool suggests that’s not correct. Similarly it raises questions about many arguments you might hear about root causes of violence.

Andrew Morral @andrewmorral.bsky.social · 05/02/2026
Huge state differences in suicide/homicide rates are often explained away by, for instance, economic conditions, demographics, firearm ownership rates, political lean, etc. How plausible are those claims, and what portion of state mortality rates cannot be so explained? ‎‎‎[1/2]

They also document a period-specific rise in adult carrying, 2016-2020, which coincides with broader social insecurity and a liberalized carry environment, suggesting that policy solutions must look beyond adolescent violence to address risks posed by durable adult-carry culture.

Andrew Morral @andrewmorral.bsky.social · 26/11/2025
They highlight two pathways to concealed gun carrying: adolescent carrying, which tends to be short-lived and triggered by direct exposure to gun violence, and adult-onset carrying, which is persistent, increasingly legal, and less tied to immediate victimization.

Andrew Morral @andrewmorral.bsky.social · 26/11/2025
This suggests an urgent need to mitigate gun theft and lost police effectiveness when loosening carry laws, since these indirect harms—not actions by permit holders themselves—appear to fuel the observed crime increase.
040
Andrew Morral @andrewmorral.bsky.social · 26/11/2025
They find that violent crime rises when states adopt right-to-carry handgun laws, an effect driven in part by a sharp increase in gun theft (50%) and diminished police performance in solving violent crimes.

No. This cannot be right. 56 additional injuries per 100k is not plausible for a 1% increase in food insecurity. Please double check this claim. Or provide the citation, and I will.

Interesting WSJ analysis of NIBRS data finds justifiable homicides rising more rapidly than total homicides in Stand-Your-Ground states, and faster than it is rising in non-SYG states. The intended effect of SYG!, but they note some real problems with application of these laws.

Specifically, homicides and car crash fatalities were trending down, but then reversed in 2015 and started rising. Between 2010 and 2014 opioid deaths increased by 0.6 (per 100k) per year, but jumped by 1.6 in 2015, and 3.5 in 2016. Depression has an earlier inflection by 2 years

Am I squinting too hard, or is there more structure to these trends than explained by COVID? In three of these series something happens around 2015, as well as peaking in 2021. Do you work with other series that look like this? Any grand theories?

New Mexico AG Torrez: One of the biggest issues we face is gun violence. We haven’t seen any surge of federal law enforcement agencies dedicated to helping us reduce gun violence. What we’ve seen instead is a lot of the performative stuff — DHS going down to paint the wall to make it hotter.

These are undoubtedly underestimates. Without mandatory reporting of lost/stolen guns (in most states) how many private citizens never report a loss, or even a theft?

Gun owners, lock up your guns. I can’t help but wonder about the thousands of guns lost and stolen from licensed gun dealers. How many were sold off the books? How many were stolen by employees who aren’t required to be vetted? It’s signals poor regulation and oversight.
