State-level firearm suicide proxy (FSS) for household gun ownership 1949-2020. Unlike most gun prevalence measures that are representative at the national or regional level, this proxy represents household gun ownership trends at the state level and is not reliant on self-reported data that are prone to social desirability bias. This extended proxy represents the longest-ranging dataset of state-level gun ownership rates to date. This dataset also includes historic data on firearm homicide and homicide counts and rates per 100,000 residents. (2023-05-18)

"The World Prison Brief (WPB) was launched on 28 September 2000 using data specially compiled for ICPS by Roy Walmsley, Director of the WPB.

The WPB is a data-base which provides information about prison systems throughout the world. It thus enables more evidence-based discussion of ways to improve prison systems in accordance with international human rights standards.

In each country page information is provided on prison populations and prison population rates per 100,000 of the national population, on the use of imprisonment for women and juveniles, on the extent of pre-trial imprisonment and on prison overcrowding, as well as a record of the national ministries responsible for prisons and contact details for prison administrations."
