DATA COLLECTION DESCRIPTION
J. 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

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.
