Several studies have examined the correlations between rates of gun ownership and gun-related as well as overall homicide and suicide rates within various jurisdictions around the world. Martin Killias, in a 1993 study covering 21 countries, found that there were substantial correlations between gun ownership and gun-related suicide and homicide rates. There was also a substantial though lesser correlation between gun ownership and total homicide rates. A later 2001 Killias study however, reported that while there was a strong correlation between gun-related homicide of women and gun-related assaults against women; however, this was not the case for similar crimes against men and that " Interestingly, no significant correlations with total suicide or homicide rates were found, leaving open the question of possible substitution effects." This study indicates correlation, but no causality. That is to say it could mean that the easier access to guns lead to more violence, or it could mean that larger amounts of violence lead to a higher level of gun ownership for self-defense, or any other independent cause.

A study by Rich et al. on suicide rates in Toronto and Ontario and psychiatric patients from San Diego reached the conclusion that increased gun restrictions, while reducing suicide-by-gun, resulted in no net decline in suicides, because of substitution of another method — namely leaping. Killias argues against the theory of complete substitution, citing a number of studies that have indicated, in his view "rather convincingly", that suicidal candidates far from always turn to another means of suicide if their preferred means is not at hand.
