The ‘Tags’ column provides additional structured information about an ACLED event. Tags provide a flexible means of refining or grouping existing variables, or providing new variables to specific contexts not already captured within the other data columns. Tags can be specific to certain (combinations of) actors and event types, themes, countries, time periods, etc. As such, some tags are hyperspecific, such as the “count every vote” tag that was introduced in the dataset for the 2020 election demonstrations in the United States. Other tags, like the “crowd size” tag, apply globally to all ‘Protests’ and ‘Riots’ events. Tags can be introduced or retired as situations on the ground and analytical needs develop or subside.
Each tag is separated by a semicolon (;) in the ‘Tags’ column. Users may filter for specific tags to quickly generate datasets related to specific aspects of political violence or demonstrations within the ACLED dataset. The full list of tags, their coverage periods, and how they are coded can be found in the table below.
As with all ACLED data, all tags coded for an event are reviewed for accuracy and consistency to ensure that they meet the criteria for inclusion.1For more, see this primer on ACLED’s Coding and Review Process. Therefore, users can filter directly on the ‘Tags’ column to pull up events related to a trend already being tracked with a tag, without needing to curate the data further to remove false positives. The ACLED Research Hub on Political Violence Targeting Women and the interactive dashboard in the United States Country Hub are examples of real-time analysis made possible by tags.
To ensure the reliability of the ‘Tags’ column, all tags go through a rigorous approval and review process before being introduced to the dataset. Based on observations and knowledge of local contexts or developing trends, potential new tags are discussed among members of the ACLED team and additions are proposed to the Research team. The Research team then evaluates and refines the criteria for coding a tag. Some tags may go through a testing phase in order to determine if the tag can be coded in a useful and reliable way. Once a tag has been approved, corrections are made to the data to ensure the tag is applied consistently for a specific region and/or time period.
