# ACLED (Armed Conflict Location & Event Data Project)

The Armed Conflict Location & Event Data Project (ACLED) is a highly respected and widely used organization and dataset focusing on the collection, analysis, and dissemination of data on political violence and protest events around the world. It has become a cornerstone resource for researchers, journalists, policymakers, and humanitarian organizations seeking to understand conflict dynamics, assess risk, and inform interventions. This article provides a comprehensive overview of ACLED, its methodology, data, applications, strengths, and limitations, aiming to be a valuable resource for beginners.

== What is ACLED? ==

ACLED is not simply a database; it is a project built around a rigorous methodology for collecting real-time data on conflict events. Established in 2014, ACLED emerged from a need for more granular, reliable, and publicly accessible information on conflict, particularly in regions experiencing rapid political change and instability.  Prior to ACLED, obtaining detailed, disaggregated data on armed conflict was often difficult and expensive, relying heavily on infrequent reporting from traditional media or limited government sources.  ACLED aimed to fill this gap by providing a consistent, systematic, and open-source resource.

At its core, ACLED tracks the location, date, actors involved, and characteristics of various types of political violence and protest events. This includes, but is not limited to: battles, violence against civilians, demonstrations, riots, and strategic changes in control of territory. Crucially, ACLED doesn’t just record *that* an event occurred, but actively seeks to understand *who* was involved, *what* the nature of the event was, and *where* it took place with a high degree of geographic precision.

== Methodology: Data Collection and Validation ==

ACLED’s data collection process is a multi-layered approach emphasizing both breadth and accuracy. It relies on a network of trained field researchers, local sources, and open-source media monitoring.  Here's a breakdown of the key steps:

* '''Open-Source Monitoring:''' ACLED analysts continuously monitor a vast array of sources, including local and international news media (newspapers, television, radio), social media (though with careful verification due to potential misinformation), and reports from NGOs and international organizations.  [[Data Sources]] are critically assessed for bias and reliability.
* '''Field Research:'''  A critical component of ACLED’s methodology is its network of local researchers and informants in conflict-affected regions. These individuals possess invaluable contextual knowledge and access to information unavailable through open-source means. They verify information, collect details on events, and provide local perspectives. This is particularly important in areas with limited media access or where reporting is restricted.
* '''Coding and Standardization:''' All collected information is then coded using a standardized coding scheme. This ensures consistency across events and allows for meaningful analysis.  The coding scheme includes detailed categories for event type, actors involved (e.g., government forces, rebel groups, militias, civilian militias), location, date, fatalities, and other relevant details.  [[Coding Schemes]] are updated periodically to reflect evolving conflict dynamics.
* '''Verification and Validation:''' ACLED employs a rigorous verification process to ensure data accuracy. This involves cross-referencing information from multiple sources, checking for inconsistencies, and consulting with experts.  Events are typically required to be corroborated by at least two independent sources before being included in the dataset.  [[Data Validation]] is a continuous process.
* '''Geocoding:'''  ACLED precisely geocodes each event, meaning it assigns specific geographic coordinates (latitude and longitude) to the location where the event occurred. This allows for spatial analysis and mapping of conflict patterns. [[Geospatial Analysis]] is a powerful tool for understanding conflict dynamics.

== Data Categories and Variables ==

The ACLED dataset contains a wealth of information organized into several key categories:

* '''Event Type:''' This classifies the nature of the event, including:
    * '''Battles:''' Armed clashes between opposing forces.
    * '''Violence against Civilians:''' Attacks directly targeting civilians, including killings, sexual violence, and abductions.
    * '''Protests:''' Demonstrations, rallies, and other forms of collective action.
    * '''Riots:''' Violent disturbances involving large groups of people.
    * '''Strategic Changes in Control of Territory:'''  Changes in control of areas, often reflecting shifts in the balance of power.
* '''Actors:''' Identifies the groups involved in the event.  ACLED provides detailed categorization of actors, including government forces, rebel groups, militias, and civilian actors. [[Actor Identification]] is crucial for understanding conflict dynamics.
* '''Date:''' The date on which the event occurred.
* '''Location:''' Precise geographic coordinates of the event.
* '''Fatalities:'''  The number of people killed as a result of the event. ACLED distinguishes between civilian and combatant fatalities. [[Fatality Analysis]] provides insights into the human cost of conflict.
* '''Sources:''' Information on the sources used to verify the event.
* '''Notes:''' Additional information about the event, providing context and details.
* '''Event ID:''' A unique identifier for each event.

ACLED also includes derived variables and indicators, such as:

* '''Conflict Intensity:'''  A measure of the level of violence in a given area.
* '''Conflict Trends:''' Analysis of how conflict patterns are changing over time.  [[Trend Analysis]] is essential for forecasting and early warning.
