This Research Note is a follow up from three previously published Research Notes by the author in this journal titled: ‘Terrorism Events Data: An Inventory of Databases and Data Sets, 1968-2017, ‘30 Terrorism Databases and Data Sets: a New Inventory’ and ‘A New Inventory of 30 Terrorism Databases and Data Sets’.
Together, the previous inventories covered 120 databases and data sets. This Research Note describes 40 more databases and data sets in the same three categories:
i. Academic, Think Tank and Independent Databases (n =32)
ii. Commercial Databases (n =2) and
iii. Governmental Databases (n =6). Most of these data refer to terrorism, yet a few are broader, covering other forms of political violence as well as armed conflicts.
