Ukrainian Government Classifies Population Data Citing Security Risks

Amid the ongoing war, the Cabinet of Ministers of Ukraine decided to restrict public access to current population data. Arsen Makarchuk, Head of the State Statistics Service, explained that demographic information is highly sensitive as it could allow the enemy to assess mobilization potential, target infrastructure vulnerabilities, and conduct psychological operations.

The State Statistics Service hopes to establish a middle ground by publishing aggregated national-level figures without regional breakdowns. Makarchuk emphasized that demographic statistics are essential for long-term state planning, private sector decision-making, and negotiations with international financial institutions. Crucially, metrics such as GDP per capita rely on accurate population counts to determine eligibility for international aid programs and membership fees for global organizations.

Currently, official dashboards only display pre-war data as of January 1, 2022, indicating a population of 41.16 million. However, Ella Libanova, Director of the Ptoukha Institute of Demography, previously shared a joint estimate with the statistics agency showing the resident population at approximately 29 million (± 300,000–500,000) based on mobile operator data and state registries. Ukraine's last official census took place in December 2001, recording 48.45 million people.
