Someone dropped by searching for “us deaths gun 1960=2012.”
I do not happen to have those numbers where I am or will be over the weekend, but finding a close approximation of the “official” numbers is easy enough. As close as the data justifies, at any rate.
In general, 49% of all homicides before 1965 were gun related, and 68% of all homicides after 1968 were gun related. The year by year homicide count from 1960 to 2011, is at this link, and multiplication by the appropriate factor will provide a result that will be within a percent of the official number.
Before 1964, multiply the official number by 0.5. For 1964 to 1966, multiply the homicide total by 0.6. In 1967 and subsequently, multiply by a factor of 0.68. This will get you very close to the official gun homicide total for any given year.
I emphasize “official” in this context. Since so many jurisdictions; almost all of them north of a line from Norfolk, Virginia to San Diego; reacted to the results of the Gun Control Act of 1968 by under reporting the number of homicides, these numbers are as much as 33% short of reality, but they are “official.”
Turning to accidental gun deaths, the situation from 1960 to 1980 is clouded. Several independent entities, including the National Safety Council, provide estimates going as far back as 1900. Those estimates vary widely, often seeming to depend on what axe was being ground.
From 1981, the Center for Disease Control’s WISQARS website will provide the official accidental firearms death rates and numbers. Which often do not agree with media reports. However, they are official. This graphic of the accidental gun death rate is derived from a “best estimate reconciling all sources” from 1900 to 1980, and CDC data from 1981 to 2010, the last year for which data is available.
