David Singer and Melvin Small CORRELATES OF WAR PROJECT: INTERNATIONAL AND CIVIL WAR DATA, 1816-1992 (ICPSR 9905) SUMMARY: This data collection describes international and civil wars for the years 1816-1992. Part 1, the International Wars file, describes the experience of each interstate member in each war. The unit of analysis is the participant in a particular conflict. When and where each interstate member fought is coded, along with battle and total deaths, pre-war population and armed forces, and whether the member in question initiated the conflict. Each war is characterized as interstate, colonial, or imperial, and major power status and/or central system membership of the warring parties is noted. Part 2, the Civil Wars file, describes when and where fighting took place, whether the war was fought within the boundaries of a major power or central system member, whether there was outside intervention and, if so, whether the intervening state was a major power, on what side they intervened, who won the war, number of battle deaths, total population, and total number of pre-war armed forces. UNIVERSE: Wars from 1816-1992 in which at least one member of the interstate system took part. NOTE: Part 5, an SPSS Export File, contains three alphanumeric variables (WARNAME, ABBREV, and NATNAME), not included in the raw data version of this collection. This data collection replaces WAGES OF WAR, 1816-1980: AUGMENTED WITH DISPUTES AND CIVIL WAR DATA (ICPSR 9044).

David Singer The University of Michigan Melvin Small Wayne State University March 1994 1 Study Description This is one of two datasets which comprise the Correlates of War: International and Civil War Data, 1816-1992 codebook and study. This part presents data on international wars. The other part presents data on civil wars. This dataset describes the experience of each interstate system member in each war. The unit of analysis is the participant in a particular conflict. The file contains 1278 logical records for 426 cases. Each case contains the values for 40 variables that describe the experience of one participant in an international war. In order to be considered a nation-participant in the interstate system, certain minimal criteria of population and diplomatic recognition were used (at least 500,000 total population and either diplomatic recognition by at least two major powers or membership in the League of Nations or United Nations). Qualifying nation- participants are classified for the period 1816-1919 as to whether or not they were members of the European Central System at the time of the war and, therefore, active and influential in European-centered diplomacy. They are also classified as to whether or not they are dealt with by other members of the interstate system as major powers. The geographical location of the war as a whole and a participant's activity in the war is coded as well as the severity of the war as determined by its duration and the number of battle-connected deaths. The pre-war population and number of persons serving in the armed forces (exclusive of police forces, unorganized militias, and gendarmerie) is also coded. This part of the dataset describes two types of international wars: Interstate wars, in which a nation that qualifies as a member of the interstate system engages in a war with another member of the interstate system. Extra-systemic wars, in which a nation that qualifies as an interstate system member engages in a war with a political entity that is not an interstate system member. Extra-systemic wars are further divided into two sub-types. The first sub-type, the imperial war, involves an adversary that is an independent political entity but does not qualify as a member of the interstate system becuse of limitations on its independence, insufficient population to meet the interstate system membership criteria or a failure of other states to recognize it as a legitimate member. The second sub-type, the colonial war, includes international wars in which the adversary was a colony, dependency or protectorate composed of ethnically differnt people and located at some geographical distance or, at least, peripheral to the center of government of the given system member. Both imperial and colonial wars are so designated both in the data and in the list of war numbers in this codebook. Users should note the following change in the codeing rules from Resort to Arms regarding extra-systemic wars. The inclusion criterion +______________ of 1000 annual average battle deaths sustained by system member participants per year has been relaxed. Extra-systemic wars are now included in the dataset if the annual average battle deaths sustained per year by all participants (both system members and non-system members) is at least 1000.
