📊 Methodology & Data Sources
This website aggregates and visualizes open-source casualty data from verified independent databases tracking the Ukraine-Russia war.
📋 Our Data Sources
This website does not collect casualty data directly. Instead, we source all data from two established open-source databases that specialize in tracking and verifying war casualties:
Russian Casualties
Source: svo.rf.gd
An independent database that tracks Russian military casualties through verified sources including obituaries, funeral announcements, and official records.
Ukrainian Casualties
Source: lostarmour.info
A comprehensive database tracking Ukrainian military casualties through verified memorial pages, official announcements, and documented sources.
⚠️ Important: The methodology described on this page refers to the data collection and verification processes used by our source databases (svo.rf.gd and lostarmour.info). We aggregate their open-source data and present it with monthly visualizations and statistics. All credit for data collection and verification belongs to these independent sources.

🔍 Source Database Verification Methodology
✅ Certification Requirements (Applied by Source Databases)
The source databases (svo.rf.gd and lostarmour.info) maintain strict certification standards for each casualty entry. Their verification process ensures zero tolerance for speculation or unverified claims.
- ✓ Name Verification: Each death includes the full name of the deceased individual
- ✓ Death Date Certification: Every entry requires a confirmed date of death
- ✓ Source Documentation: Each casualty has a social media link to funeral/obituary or official announcement
- ✓ Real Documented Deaths Only: Every number represents an actual, documented death - no estimates, no projections, no speculation
- ✓ Zero Speculation Policy: Only figures that can be directly traced to a verified source with name, date, and documentation link are included

❓ Frequently Asked Questions
How accurate is this casualty data?
Our data comes from verified memorial databases (svo.rf.gd and lostarmour.info) that track confirmed casualties. We sample 500+ memorial pages monthly and scale to match official totals. Numbers represent confirmed minimum losses.
How often is the data updated?
Data updates are dependent on our sources capabilities to find the new data. The updates are made approximately one time per month, but it's possible to last longer depending on the sources capabilities.
What are the data sources?
Ukrainian casualties: ualosses.org memorial database with individual death dates. Russian casualties: svo.rf.gd verified named personnel list. Both sources independently verify casualties before listing.
What's the difference between confirmed and unconfirmed casualties?
Confirmed casualties have specific known death dates. Unconfirmed entries have estimated dates (shown in parentheses on memorial pages) due to delayed reporting or incomplete information.
📈 Our Statistical Analysis & Visualization
While our source databases handle data collection and verification, this website adds value through statistical analysis and data visualization:
Data Processing & Aggregation
Monthly Aggregation
- • Date-based grouping by month
- • Confirmed vs estimated categorization
- • Geographic distribution analysis
- • Military unit breakdown
- • Temporal trend identification
Statistical Analysis
- • Monthly casualty rate calculations
- • Trend line analysis
- • Comparative statistics
- • Historical pattern recognition
- • Data visualization generation
Transparency & Limitations
- 📊 Data Completeness: The numbers represent documented casualties with verifiable sources. Actual casualties may be higher due to unconfirmed deaths, missing records, or unreported losses.
- ⏱️ Reporting Lag: There is an inherent delay between when casualties occur and when they are documented in public sources. Recent months may show lower numbers that will increase as more information becomes available.
- 🔍 Verification Standards: We prioritize accuracy over speed. Only casualties meeting strict verification criteria from our source databases are included.
- 🌐 Source Limitations: Our data is limited to what is publicly documented and verified by our source databases. Not all casualties become public knowledge.
- 📈 Statistical Nature: This is a statistical analysis of verified public data, not an official military accounting.
🔄 Data Update Process
Source Database Updates
Our source databases (svo.rf.gd and lostarmour.info) continuously monitor and update their casualty records as new verified information becomes available.
Our Update Schedule
We update our visualizations and statistics monthly, pulling the latest verified data from our source databases to ensure accuracy and timeliness.
