Firearm & Injury Center at Penn ficap@uphs.upenn.edu (Version 2009) 3 A NOTE ABOUT THE DATA SOURCES Data are presented from available sources to illustrate the magnitude of firearm injury in terms of deaths, nonfatal injuries, and other effects on society. Thirteen national data systems are available in the U.S., each managed by a single federal agency, to compile information on firearm mortality, morbidity (nonfatal injury outcomes), and associated risks and behaviors. 1 These data systems primarily collect broad-based information for surveillance and have been created largely in the last 10-15 years. Some advances in these data systems have occurred; however, significant limitations remain. Most importantly, with the exception of the National Violent Death Reporting System, systems are not linked. Important information, such as community-level data, circumstances of firearm deaths, types of weapons used, victim-offender relationships, involvement of substance abuse, or place where the firearm injury occurred, are not consistently collected, leaving the data fragme nted. The nonfatal injury data for firearms are particularly limited, as they remain non-specific and difficult to use for epidemiological study. The main data sources cited in this resource book are: ? The Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics (NCHS) publishes annual data on deaths from different causes in the National Vital Statistics System. It takes about 18 months to collect, compile, verify and release these statistics to the public, accounting for the lag time in much of the data reported in this resource book. Beginning in 1999, mortality data have been coded using ICD-10 codes. Graphs that include data from 1999 have a break in the trend line because the NCHS has recommended not combining these data. These data can be accessed through: www.cdc.gov/ncipc/wisqars . More detail is available through: wonder.cdc.gov . ? The Federal Bureau of Investigation (FBI) Uniform Crime Reporting (UCR) system compiles crime statistics annually from 17,000 city, county, and state law enforcement agencies that submit data voluntarily. The UCR publishes crime data annually, with a lag time of approximately one year, and is considered the most reliable crime data on homicides. UCR data provide detail on circumstances, and relationships of victims and suspects, when known. The voluntary nature of reporting can cause coverage and comparison issues. ? The Bureau of Justice Statistics (BJS) in the Department of Justice (DOJ) provides the National Crime Victimization Survey (NCVS), collecting data on reported and unreported fatal and nonfatal violent crimes against persons 12 or older. Survey data include crimes that were not reported in law enforcement or health statistics and can be useful in triangulating data. These data are subject to reporting biases and sampling issues. ? The National Electronic Injury Surveillance System (NEISS) provides data for nonfatal firearm injury. NEISS data is collected from a sample of 91 hospitals in the U.S. by the Consumer Product Safety Commission and is extrapolated to the national population to estimate the extent of nonfatal injuries. C PSC’s National Electronic Injury Surveillance System (NEISS) is a national probability sample of hospitals in the U.S. and its territories.
