The data on gunshot injuries in the US from 1999 to 2009 shows a clear and steady increase in both fatal and non-fatal gunshot injuries, rising from a low of 28,000 fatal gunshot injuries in 1999 to over 31,000 gunshot fatalities in 2009 (the last year for which data is available). The data on non-fatal gunshot injuries shows a similar pattern. This same pattern is also observed in the FBI NICS data; from a low of 8.5 million NICS inquires in 2000, steadily increasing to over 16 million inquiries in 2011, almost a doubling of transactions in a little more than ten years. Interestingly, the data on bicycle injuries shows no such trend: both the numbers for fatal and non-fatal bicycle injuries jump around a good deal, without any clear overall increase or decrease. A regression of injuries over time shows that bicycle injuries (both fatal and non-fatal) did not change significantly over time (Beta did not differ significantly from 0), while the variable for both gun injuries (fatal and non-fatal) and gun sales were all increasing significantly over time (Betas differed significantly from 0 and were all positive).
