After a long time I created a map I want to share. Data from @UU_Peace (UCDP GED 24.1). Each dot = a violent event since 1989 🎨 Color = type of violence ⚖️ Size = fatalities (best estimate)

Some key findings: - Most differences stem from how projects handle ambiguity & uncertainty in poor information environments. - Auxiliary coding rules (e.g., counting "people killed" as 2 vs 10 fatalities) explain 90% of differences in some cases. (2/3)

- Source evaluation standards matter more than sourcing strategies. - Stable definitions are essential for reliable measurement, not a flaw. (3/3)

New @UCDP data shows conflict is at a historic high. In 2024, the world saw 61 state-based conflicts - the most since WWII. Africa tops the list, nearly doubling in a decade. “Now is not the time to retreat from global engagement," PRIO’s Siri Aas Rustad warns. prio.org/news/3616

“The number of interstate conflicts doubled from two in 2023 to four in 2024. This is the highest number recorded since 1987, reflecting a trend in which interstate conflicts have become increasingly common since 2016.”

Since 2010, the number of conflicts involving states has almost doubled, and the total number of deaths has increased five-fold. Read more about the new UCDP data in this @JPR_journal open access article: journals.sagepub.com/doi/10.…

In their new paper, Schumann and Bara connect different forms of war-related UCDP violence and specific civil wars. A valuable read for anyone looking to understand how various forms of violence intersect and impact conflict dynamics. doi.org/10.1177/205316802513…
