Introducing Comparative Death Penalty Database (CDPD)

The death penalty is a unique form of punishment as it is the most consequential penalty with no options for reversibility. Politically, it is a highly controversial form of punishment, the usage of which varies strongly between and within countries over time. Existing databases on death penalty usage generally cover a time period from the 1950s and onwards. In this article, we introduce a new database that covers the period 1800–2022 for all currently independent countries in the world. We provide a yearly categorization of death penalty status as well as changes of the status. In descriptive analyses, we show how the new data provides a more comprehensive picture of the development of death penalty trends worldwide. The database provides researchers with new opportunities to study the death penalty from a variety of perspectives.
