The Uppsala Conflict Data Program (UCDP) has recorded ongoing violent conflicts since the 1970s. The data provided is one of the most accurate and well-used data-sources on global armed conflicts and its definition of armed conflict is becoming a standard in how conflicts are systematically defined and studied.

Uppsala Conflict Data Program — an Overview
The Uppsala Conflict Data Program (UCDP) collects information on a large number of aspects of armed violence since 1946. Since the 1970s, the Uppsala Conflict Data Program (UCDP) has recorded ongoing violent conflicts. This effort continues to the present day, now coupled with the collection of information on an ever broadening scope of aspects pertaining to organised violence, such as the resolution and dynamics of conflict. The UCDP data is one of the most accurate and well-used data-sources on global armed conflicts and its definition of armed conflict is becoming a standard in how conflicts are systematically defined and studied. Data on armed conflicts have been published yearly in the report series States in Armed Conflict since 1987, in the SIPRI Yearbook since 1988, the Journal of Peace Research since 1993 and in the Human Security Reports since 2005. In addition UCDP researchers conduct theoretically and empirically based analyses of armed conflict: its causes, escalation, spread, prevention and resolution. These studies are regularly featured in international journals and books.
Since 2004, the UCDP also operates and continuously updates its online database on armed conflicts and organised violence, in which several aspects of armed conflict such as conflict dynamics and conflict resolution are available.
