This vital work will provide the foundation for policy decisions, resource allocation, and community planning for the next decade.

Job description

The Senior Business Analyst (BA) plays a key role in shaping how the Census is designed, delivered, and continuously improved. Working within the central End‑to‑End (E2E) Service Design Team, the BA ensures that the Census operates as a coherent, integrated, and user‑centred service across all business areas. This role collaborates with a wide range of stakeholders across ONS, delivery suppliers, enabling partners, and the Devolved Governments to support a unified UK‑wide Census experience.

The post holder may work across the full breadth of the high‑level Census design or specialise in particular business services—such as Field Operations, Communal Establishments (CE), Public Support, Contact Centre, Questionnaire Operations, or other core service components.
