from December 8, 2012 provides some perspective on falling absolute numbers (and thus a falling rate) of gunshot deaths.
"Crime experts who attribute the drop in killings to better policing or an aging population fail to square the image of a more tranquil nation with this statistic: The reported number of people treated for gunshot attacks from 2001 to 2011 has grown by nearly half.
. . . .
"After a steady decline through the 1990s, the annual number of homicides zigzagged before resuming a decline in 2007, falling from 16,929 that year to an estimated 14,722 in 2010, according to FBI crime data.
"At the same time, medical data and other surveys in the U.S. show a rising number of serious injuries from assaults with guns and knives. The estimated number of people wounded seriously enough by gunshots to require a hospital stay, rather than treatment and release, rose 47% to 30,759 in 2011 from 20,844 in 2001, according to data from the Centers for Disease Control and Prevention's National Electronic Injury Surveillance System-All Injury Program. The CDC estimates showed the number of people injured in serious stabbings rose to 23,550 from 22,047 over the same period."
Emergency medicine for gunshot victims has improved enormously in the last twenty years, and many people who are shot by criminals now survive for a lifetime of permanent disability rather dying on the street. A crime can only be classified as a "homicide" by the uniform statistical methods if someone dies, but a crime can still be very serious and harmful to the victim if it involves a gunshot by a criminal.
