Hackers leak Rosstat data showing over 450,000 Russian soldier deaths

A data leak from the Russian statistical agency Rosstat indicates that 450,100 Russian soldiers have died in the war as of late August, roughly 100,000 per year. This figure is consistent with other independent estimates.

## What the Rosstat leak reveals

A hacker group has published classified data from the Russian statistical agency **Rosstat** regarding military deaths in the Ukraine war. By the end of August, the cumulative total stood at **450,100** fatalities, equivalent to approximately **100,000** deaths per year. The database is searchable and allows for queries.

Researcher **Janis Kluge** noted that the figures align with other independent estimates and that the data includes a regional breakdown. The most striking chart is constructed using dates found on death certificates.

## The nuance of missing persons

There is a caveat worth noting. The increase in annual deaths may be partly linked to soldiers who went missing and were declared dead much later. In other words, the series does not necessarily reflect when each casualty occurred, but rather when it was certified.

This lag matters for interpreting annual trends. A spike in a specific year could result from administrative regularization of old cases, not a combat peak during that period.

## Casualties excluded from the count

The Rosstat data is incomplete. It excludes losses from mercenary groups like **Wagner**, recruits taken from prisons, militias from the self-proclaimed republics of **LNR** and **DNR** and occupied territories, foreign fighters from Africa, and military personnel from allied countries, such as North Koreans.

These categories largely bypass ordinary Russian statistical records, meaning the actual total would be higher. Therefore, the leak describes a floor, not a ceiling.
