The final Statistics on International Development (SID) publication, released on 17 September 2026, provides a comprehensive overview of UK Official Development Assistance (ODA) spend. This statement, published twice a year – provisional data in the spring and final data in the autumn – details the total amount allocated, offering a project-level dataset alongside summary figures. The release, designated as Accredited Official Statistics, is a key mechanism for tracking UK contributions to global development efforts, as outlined by the Foreign, Commonwealth & Development Office (FCDO).; see the full statement.
Background
The SID series has been published since 2017, offering data from that year onwards. The timing of the releases is governed by several factors, including the timetable for reporting UK ODA figures to the OECD, the Office for National Statistics’ (ONS) GNI estimates, and the processing and quality assurance of spending data. The statement does not address the specific methodologies used in calculating ODA spend, nor does it detail the contributions from other ODA contributors. The release timetable is intended to ensure a consistent and orderly publication process.
Analysis
The provision of provisional and final data allows for a degree of scrutiny and adjustment. The statement does not address the potential for revision as more complete data becomes available. The release’s designation as Accredited Official Statistics indicates a commitment to robust data quality standards, as confirmed by the Office for Statistics Regulation (OSR) in its 2023 review. This review confirmed that SID continues to meet the requirements of the Code of Practice for Official Statistics. The release timetable reflects the complexities of gathering and validating data across multiple government departments and international organisations.
Implications
The availability of detailed ODA spend data has implications for policymakers evaluating development effectiveness and for international organisations tracking aid commitments. The release provides a foundation for assessing UK contributions to specific sectors and geographies. The statement does not address the potential impact of this data on future aid allocation decisions. The detailed project-level dataset allows for a more granular understanding of where funds are being directed.
Outlook
Should the provisional data be revised following the publication of final data in the autumn, the impact on the overall ODA spend figure would be reflected. If the ONS publish the latest GNI estimates, this could influence the methodology used for calculating ODA spend. Should the timing for processing and quality assuring the spending data remain consistent, the release timetable will continue to provide a predictable cadence for the publication of these statistics.
