Here I offer a spreadsheet containing homicide / lethal conflict rates for a number of stateless and quasi-stateless societies at different points in time.
I omit a number of datapoints from the main dataset, placing them in a separate sheet, but readers may judge for themselves whether they agree or disagree with my omissions.
I use Mark Cooney's definitions for "homicide" and "lethal conflict," where lethal conflict includes deaths from intergroup warfare and homicide does not. However, it is not always clear from my sources whether they are offering homicide or letahl conflict rates. I recommend examining the sources I cite before using the data offered.
