Résumé
“Statistics in this report are based on self-reported data collected through face-to-face interviews with a national sample of state and federal prisoners in the 2016 SPI. (See Methodology.) The 2016 SPI data collection was conducted from January through October 2016. The SPI was formerly known as the Survey of Inmates in State and Federal Correctional Facilities (SISFCF). The Bureau of Justice Statistics (BJS) has periodically conducted the survey since the 1970s, with the most recent iteration fielded in 2004. The survey collects information from prisoners on a variety of topics, including firearm possession during the crime for which a prisoner was serving time and how the firearm was used during the crime. It also collects information on the method, source, and process that prisoners used to obtain the firearm.”--Page 2.
