To provide a nationally representative estimate of the proportion of gun owners who report a child has independent access to one of their guns, and to describe characteristics of these gun owners relative to other gun-owning parents.

We conducted a cross-sectional analysis of online survey data collected in 2019 from a nationally representative sample of US adults in households with firearms (n = 4030, response 65%). The sample comprised gun-owning respondents living in homes with children (n = 689) who were asked questions about their firearms, including how they were stored, and about who other than themselves had access to their guns: “If you were not there, who in your household could get one of your guns (and load it if it is not loaded already) if they needed to?”

Twelve percent of US gun owners in homes with children report that a child has independent access to one of their guns (about one-fifth of those having children under age 12 years only). Gun owners who reported child access were more likely than those who reported no child access to store guns unlocked and loaded, but still one-fifth of those reporting access stored all guns locked and unloaded.

We find that more than 10% of gun owners with children report that a child can independently access one of their guns, including parents who store all guns locked and unloaded suggesting that guidance to parents should focus on access in addition to firearm storage.
