What you should know about this indicator

A state-based conflict is a conflict between two armed groups, at least one of which is a state, that causes at least 25 deaths during a year. This includes combatant and civilian deaths due to fighting.

Deaths in state-based conflicts by region
The best estimate of the number of deaths of combatants and civilians due to fighting in interstate, intrastate, and extrasystemic conflicts that were ongoing that year.

Deaths in state-based conflicts

Sources and processing

This data is based on the following sources

This dataset is UCDP's most disaggregated dataset, covering individual events of organized violence (phenomena of lethal violence occurring at a given time and place). These events are sufficiently fine-grained to be geo-coded down to the level of individual villages, with temporal durations disaggregated to single, individual days.

There are 258 countries in the world. Greenland as separate from Denmark. Most users will want this file instead of sovereign states, though some users will want map units instead when distinguishing overseas regions of France.

Natural Earth shows de facto boundaries by default according to who controls the territory, versus de jure. Optional point-of-view (POV) variants are available for several dozen countries in the next section.

Countries distinguish between metropolitan (homeland) and independent and semi-independent portions of sovereign states. If you want to see the dependent overseas regions broken out (like in ISO codes, see France for example), use map units instead.

Each country is coded with a world region that roughly follows the United Nations setup.

Countries are coded with standard ISO and FIPS codes. French INSEE codes are also included.

Includes some thematic data from the United Nations, U.S. Central Intelligence Agency, and elsewhere.

This is the most detailed. Suitable for making zoomed-in maps of countries and regions. Show the world on a large wall poster:

All users of Natural Earth are highly encouraged to read about data sources and manipulation in the Data Creation section.

This project has generated a dataset on battle deaths (number of soldiers and civilians killed in combat) in state-based armed conflicts for the period 1946-2008.

The dataset is compatible with the UCDP/PRIO Armed Conflict Dataset for the period 1946–2008.

A longer time series (1900-1997) compatible with the Correlates of War database was included in the first version (v1) of the Battle Deaths Dataset, available from the downloads section.

For academic exchanges on the PRIO data, see the following articles and rebuttals:

There are no plans to update the PRIO battle deaths dataset beyond 2008. The Uppsala Conflict Data Program (UCDP) maintains a similar dataset from 1989, which is updated annually. For this dataset in different formats, as well as a codebook, go to the UCDP Battle-Related Deaths Dataset.

While the definitions are very similar, the coding practices may differ somewhat, and we generally recommend users of the two datasets to point out that these are two different, although closely related, datasets.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator

Data prior to 1989 is sourced from PRIO. Data since 1989 is sourced from UCDP.

For conflict years without a best deaths estimate in the PRIO data, we conservatively coded the low estimate.
