Much of my research involves gathering new data.  Here is a description of those data sets, referenced to specific papers that you can find in the "Research" section of this website.

-Cross-sectional data on manpower deployments, rebel forces, and the area of operations for 171 counterinsurgency campaigns since World War I. (Used in "Manpower and Counterinsurgency").

-Event data on armed encounters between the U.S./British and more than 100 Native American tribes, comprising roughly 3,000 engagements between the founding of Jamestown and the battle of Wounded Knee. (Used in my dissertation and in the working paper below.)

-Cross-sectional data on roughly 400 National Intelligence Estimates declassified (but since suppressed) by the CIA's Historial Review Program; the data set codes information about the number and kind of predictions that each of these estimates presents. (See "Assessing Uncertainty in Intelligence.")

-Time series data on monthly violence trends within 40 Coalition areas of operation during the Surge in Iraq. (See "Testing the Surge: Why Violence Declined in Iraq in 2007").

-Cross-sectional data on insurgent casualties spanning 285 conflicts since 1810. (Used in my dissertation.)

If you are interested in these data, you will find replication materials for my published work on this website, and you can contact me through the address listed above.  Here is a bibliography that lists the more than 500 sources that were used to code the data on insurgencies that appears in my paper on manpower and in my dissertation. This working paper explains and assesses my data on the American Indian Wars, and then extrapolates from these data in order to derive new estimates of the severity of these conflicts.
