Few urban Mexican homes contain firearms 

Data from a 2017 household telephone survey of over 1,300 adults living in nine Mexican cities found that only 3% of homes contain firearms.  Most  individuals who report owning firearms possess only one gun, having purchased it recently for self-defense.  Respondents were much more likely to believe that crime in Mexico would increase rather than decrease if guns were allowed in more places.  The article “What is the level of household gun ownership in urban Mexico? An estimate from the first Mexican survey on gun ownership 2017” by David Perez Esparza and David Hemenway appeared in Injury Prevention, online first.
