Mass killing is a concept which has been proposed by genocide scholars who wish to define incidents of non-combat killing which are perpetrated by a government or a state. A mass killing is commonly defined as the killing of group members without the intention to eliminate the whole group, or otherwise the killing of large numbers of people without a clear group membership.
Mass killing is used by a number of genocide scholars because genocide (its strict definition) does not cover mass killing events in which no specific ethnic or religious groups are targeted, or events in which perpetrators do not intend to eliminate whole groups or significant parts of them. Genocide scholars use different models in order to explain and predict the onset of mass killing events. There has been little consensus and no generally-accepted terminology, prompting scholars, such as Anton Weiss-Wendt, to describe comparative attempts a failure. Genocide scholarship rarely appears in mainstream disciplinary journals.
In the United States, the Investigative Assistance for Violent Crimes Act of 2012, passed in the aftermath of the Sandy Hook Elementary School shooting in Newtown, Connecticut, clarified the statutory authority for federal law enforcement agencies to provide investigatory assistance to the States, and mandated across federal agencies, including the Departments of Justice and Homeland Security, a definition of "mass killing" as three or more killings during an incident, while making no reference to the choice of weapon.

Manus Midlarsky also focuses on leaders' decision making but his case selection and general conclusions are different from Valentino's. Midlarsky has a narrower definition of the dependent variable and only analyzes three case studies (the Armenian genocide, the Holocaust, and the Rwanda genocide). Midlarsky tries to explain why individuals may comply with the culprits, why politicide rather than genocide happened in Cambodia (Cambodian genocide), and why ethnic minorities, such as Greeks in the Ottoman Empire and Jews in the Second Polish Republic, were not targeted for genocide. Like Michael Mann and Valentino to a lesser extent, Midlarsky mainly addresses genocides that did not take place. Both Midlarsky and Valentino mainly focus on proximate conditions, while Mann considers genocide within the broad context of ideologies and nation-states development.
These data are intended mostly for statistical analysis of mass killings in attempt to identify the best predictors for their onset. According to Harff, these data are not necessarily the most accurate for a given country, since some sources are general genocide scholars and not experts on local history. A comparative analysis of the Yugoslav data in two databases revealed a significant difference between the figures of killed per years and low correlation between Rummel's and Harff's data sets. Tomislav Dulić criticized Rummel's generally higher numbers as arising from flaws in Rummel's statistical methodology, and Rummel's response was not convincing.
Another comparative analysis of the two complete databases by Atsushi Tago and Frank W. Wayman revealed that the significant difference between the figures is explained by Harff's dataset of politicide-geoncide being essentially a subset of Rummel's dataset, where he includes other types of killings in addition to politicide-genocide.
