Bénin revises GDP calculation method, 2023 economic output jumps by 25.2%

Benin’s National Institute of Statistics and Demography (INStaD) has completed a significant overhaul of the country’s national accounts, establishing 2023 as the new base year in place of the previous 2015 reference. This statistical adjustment has resulted in a substantial upward revision of the country’s 2023 GDP to 14 020.2 billion CFA francs, representing a remarkable 25.2% increase—illustrating a more accurate reflection of Benin’s evolving economic landscape.

A shift toward more precise economic measurement

This methodological change aligns with the United Nations’ 2008 System of National Accounts, which advocates for regular updates to the base year to enhance the reliability of economic estimates. While the standard five-year revision cycle was disrupted by global economic shocks between 2019 and 2022, 2023 was selected for its relative economic stability in Benin. The intervening years also saw extensive statistical operations that captured recent economic transformations with greater precision.

Sector-specific contributions to growth

Following the rebasing, Benin’s 2023 GDP stands at 14 020.2 billion CFA francs under the new 2023 base, compared to the previous estimate of 11 200.7 billion CFA francs under the 2015 base—a 25.2% adjustment. It is important to note this revision does not indicate a sudden surge in wealth creation but rather reflects improved statistical coverage and more accurate economic activity measurement.

INStaD highlights that the upward revision stems from enhanced data collection across all sectors, with the secondary sector experiencing the most significant increase at 56.1%. On the demand side, the most notable changes involve gross fixed capital formation, which has been revised upward by 36.6%, driven by better accounting of investments in infrastructure, construction, and productive equipment—particularly those tied to economic zones.

Collaboration and future projections

The rebasing process received support from multiple technical and financial partners, including the World Bank, AFRISTAT, the IMF, GIZ, the African Development Bank, STATFRIC, ECOWAS, and WAEMU. Peer reviews also involved national statistics institutes from Burkina Faso and Mali.

Looking ahead, INStaD has announced plans to extend this work by retroactively recalculating national accounts from 1999 to 2022. This initiative will provide Benin with a comprehensive, updated series of national accounts based on the new 2023 benchmark.
