The reported, or calculated annual crude rate of completed, intentional homicide committed with an 'other or unspecified firearm,' in which the victim is male, per 100,000 male population, in years descending.

Where the rate is calculated by GunPolicy.org, a matched population estimate is also cited.

In the United States, this category is confused by inaccurate and conflicting data published, suppressed or labelled as unreliable by the Centers for Disease Control and Prevention (CDC) and the Federal Bureau of Investigation (FBI). Suppression can result in zero values where in fact homicides did occur.

Incomplete classification by local agencies can also result in a significant proportion of events being categorised as 'unknown cause' or similar.

Before quoting these datasets, please follow the citation links for a description of the considerable differences between them and the reasons for data suppression.
