Editing Mass killing (section)

== Global databases of mass killings ==
At least two global databases of mass killings are available. The first compilation by [[Rudolph Rummel]] covers a time period from the beginning of the 20th century until 1987 covering [[democide]], while the second compilation by [[Barbara Harff]] combines [[politicide]] and [[genocide]] since 1955. The Harff database is the most frequently used by genocide scholars, while the Rummel database is a good framework for studying mass killings during the 1900–1987 period.{{sfn|Tago|Wayman|2010}}

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.{{sfn|Harff|2017}} 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{{sfn|Dulić|2004}} Rummel's generally higher numbers as arising from flaws in Rummel's statistical methodology, and Rummel's response{{sfn|Rummel|2004}} was not convincing.{{sfn|Gleditish|2017|p=10}}

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.{{sfn|Tago|Wayman|2010}}
