State Security Forces Data Set
The State Security Forces (SSF) data set includes information on the command, staffing, equipment, and deployment of 375 security forces in 110 states, 1960-2010. A country-year version includes indicators of security sector fragmentation and coup-proofing.
The data was collected to test arguments about the effectiveness of "counterbalancing" the military with militarized police, national guards, militias, or other independent security forces as a coup-prevention strategy. It may also be of use in studies of repression, military effectiveness, and state capacity.
I have drawn upon over 2,200 primary and secondary sources. The sources include academic works on military institutions and civil-military relations in each state, historical news sources, annual defense publications, government websites, and reports from non-governmental organizations.
A paper introducing the dataset is currently under review. Please contact me for a copy. For an illustration of how the data can be used to capture rulers' efforts to coup-proof, see: "Preventing Coups d’état: How Counterbalancing Works."
