Russia's combat losses in the data of Rosstat

This interactive analysis estimates Russian deaths connected to the war against Ukraine using Rosstat death-certificate records. It counts deaths registered in Russia, including records marked with ICD-10 code Y36 (“operations of war”), code Y89.1, or wording that identifies combat. Because many records lack a cause, it also estimates combat deaths among them by measuring excess male mortality against ordinary levels, with separate assumptions for front-line and rear regions. The estimate is kept distinct from deaths confirmed by certificate details. The records do not capture wounded or missing people, foreign mercenaries whose deaths are not registered in Russia, or all deaths in occupied territory, so the total toll is higher than the count shown.

Maps and charts break records down by residence, place of death, region, age, sex, and year; residence indicates where people came from, not where they died. Code Y36 can also include civilians killed in attacks, though the overall profile is mostly men of military-service age. The analysis warns that recent deaths are seriously undercounted because certificates arrive late: 26% are registered within a month, 69% within six months, and 99% within a year. It therefore tracks when records enter the database and adjusts forecasts for registration delays, rather than treating recent declines by death date as real. Duplicate versions are consolidated: each death record has 2.55 versions on average, so counting rows would inflate totals. Users can search by certificate or record number, or by place, but names are not included.
