In May 2025, Saudi Arabia’s General Authority for Statistics (GASTAT) announced the Kingdom’s first comprehensive GDP revision since 2010, increasing 2023 estimates by 14.1% and raising the non-oil share from 47.5% to 53.2%. This commentary assesses whether the revision reflects a genuine improvement in measurement or a methodological artifact. Drawing on GASTAT’s official methodology documentation, the International Monetary Fund’s 2025 Article IV assessment, international rebasing precedents, and independent physical output indicators, we find the revision broadly credible. The 14.1% increase over a 15-year gap is modest by international standards and smaller on an annual basis than comparable exercises in Nigeria, Ghana, or Kenya. The revision is concentrated in domestically verifiable sectors. Construction and manufacturing account for 45% of the increase, rather than harder-to-audit services. Crucially, GASTAT’s Industrial Production Index provides independent verification: manufacturing physical output grew 11% from 2021 to 2023, confirming real activity expansion alongside measurement improvements. Construction presents a more complex picture. Value-based indicators, including contract awards at +90% and gross fixed capital formation at +60%, diverge sharply from physical output, with cement production -10%. This pattern suggests high-value megaprojects with significant import content rather than proportional growth in domestic output. For analysts and policymakers, the prudent approach is to adopt the revised series as authoritative while using physical indicators as cross-checks when assessing Vision 2030’s economic transformation.
