Job Description

Introduction

Established in 1951, IOM is a Related Organization of the United Nations, and as the leading UN agency in the field of migration, works closely with governmental, intergovernmental and non-governmental partners. IOM is dedicated to promoting humane and orderly migration for the benefit of all. It does so by providing services and advice to governments and migrants.

Project Context and Scope

The State Statistics Service of Ukraine (SSSU), with support from IOM, is advancing work on the development of a register-based population model and related information and communication technology (ICT) systems for data processing, exchange, analysis and visualization. This work is intended to strengthen the production of official statistics on the de facto population in Ukraine, including its demographic characteristics, mobility and migration, through the improved use of administrative data sources and state registers.

The initiative will support the production of timely and accurate population estimates, including by sex, age and regional distribution, and is aligned with UNECE and Eurostat recommendations as well as Ukraine’s preparation for EU accession, particularly under acquis Chapter 18 “Statistics” and Chapter 22 “Regional Policy and Coordination of Structural Instruments” with Regulation (EU) 2025/2458 on European Statistics on Population and Housing (ESOP, adopted September 2025, applicable from 2028). It is also important for future preparation for a national population census after the end of Russia’s war against Ukraine, taking into account war-related migration dynamics, including returns from abroad, and for improving the inclusion of internally displaced persons (IDPs) in national and local estimates. Overall, this support is expected to strengthen the institutional capacity of the SSSU, contribute to preparation for the 2030 census round, and further align Ukraine’s statistical system with international and European standards.

The Consultant will be responsible for the following tasks:

1. Develop functional and technical requirements for the future Statistical Population Register (SPR).
2. Define key system functions, including data ingestion, linkage, validation, processing, storage, updating, audit trail and reporting.
3. Conduct a capability inventory and gap analysis of the priority administrative registers in relation to SPR ingestion requirements - DRACS, the State Register of Individual Taxpayers, the Pension Fund of Ukraine, the State Migration Service, NHSU, the Ministry of Education and Science, the Ministry of Social Policy (UISSS), the Unified State Demographic Register, etc.
4. Define interoperability requirements for integration with multiple administrative data sources and external systems, via the Trembita government data-exchange system, using SDMX as the data-exchange standard for statistical content.
5. Contribute to the preparation of technical specifications for future software development.
6. Support the preparation of feasibility-oriented technical documentation to inform future system design and implementation.
7. Propose requirements related to high-level system architecture, operational workflow and maintainability.
8. Define requirements related to data security, integrity, confidentiality and access control.
9. Propose requirements for user roles and permissions.
10. Define technical requirements for anonymization and controlled statistical use of data.
11. Prepare a user-role catalogue, access-pattern documentation, and a one-page architectural blueprint suitable for stakeholder communications during the build phase.
12. Ensure that technical documentation aligns with the UNECE statistical-modernisation framework and it is understandable and usable by both technical and institutional stakeholders.
13. Perform such other duties as may be assigned.
