aThe data in this table derive from a survey (much more exhaustive than those referenced in tables 1 and 2) of legal firearms ownership in numerous nations that was carried out by researchers provided by the government of Canada under the auspices of the United Nations Economic and Social Council, Commission on Crime Prevention and Criminal Justice in 1997. The entire survey was published as a report to the secretary- general on April 25, 1997, as E/CN.15/1997/4. That report is analyzed in some detail in an unpublished paper (“A Cross Sectional Study of the Relationship between Levels of Gun Ownership and Violent Deaths”) written by the leading English student of firearms regulation, retired chief superintendent of English police Colin Greenwood of the Firearms Research and Advisory Service. We are indebted to Chief Superintendent Greenwood for the opportunity to review his paper.
bThe firearms ownership figure for Austria may be an undercount because an Austrian license is not limited to a single firearm but rather allows the licensee to possess multiple guns.
