In an article for the Telegraph, Magnus Öberg and Therese Pettersson, both from @ucdp.bsky.social, discuss how indirect deaths from war far exceed the fatalities recorded in conflict datasets.

🎉 UCDP Research Coordinator Therese Pettersson has been named to Clarivate’s 2025 “Highly Cited Researchers” list. This is likely the first time a researcher from our department has received this distinction.

Congratulations Therese and the entire @ucdp.bsky.social team on this achievement! 💪

Today we had the pleasure of welcoming a delegation from @sidasweden.bsky.social‬, which manages Sweden's foreign aid. Thank you for this opportunity to hear about your impactful work around the globe, and discuss how our research and data could further support these efforts!

Israeli military's own data shows 83% of deaths in Gaza were civilians.

UCDP's Therese Pettersson calls the ratio "unusually high", comparable to Rwanda 1994 and Mariupol 2022.

This article highlights immense civilian suffering and raises questions about the reliability of wartime casualty data.

📊 The two most used sources of conflict data are @ucdp.bsky.social and ACLED. A recent article examines which factors drive the differences observed in these two datasets.

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

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)

A new article by UCDP's Magnus Öberg and Mert Can Yilmaz in Research & Politics reveals that differences between major conflict datasets aren't driven by sourcing strategies or inclusion thresholds as previously claimed (1/3)

In their latest paper, @realmps.bsky.social and @corinnebara.bsky.social dive into the connections between 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.
