South Africa’s Economy Is Bigger Than Previously Estimated, Stats SA Reveals

South Africa’s economy is larger than previously estimated, according to Statistics South Africa (Stats SA), following a comprehensive rebasing and benchmarking exercise of the country’s Gross Domestic Product (GDP).

The latest revision, released on Thursday, 29 October 2026, shows that the country’s economy was approximately 4.9% larger in 2022 than previously reported, providing an updated picture of the size and structure of economic activity.

According to Stats SA, the revised estimate puts South Africa’s GDP for 2022 at approximately R6.99 trillion, compared with the previous estimate of R6.667 trillion.

The exercise also revised the country’s nominal GDP for 2025 upwards from R7.642 trillion to R8.044 trillion, representing an increase of 5.3%.

The statistical agency explained that the exercise involved changing the base year used to measure the economy from 2015 to 2022, while incorporating updated information, new data sources and improved methodologies.

Rebasing and benchmarking are conducted periodically to ensure that national economic statistics reflect changes in the structure of the economy and provide a more accurate representation of economic activity.

One of the most significant findings was the increased contribution of the mining industry, which recorded a 12.5% upward revision.

Stats SA attributed this adjustment partly to improved coverage of illegal mining activities, which had previously been difficult to capture accurately in official economic measurements.

The finance, real estate and business services industry also recorded a substantial upward revision of 9.1%. This was largely linked to improvements in the methodology used to calculate owner-occupied housing services.

The updated figures also incorporate activities that form part of the non-observed economy, including informal businesses, illegal mining, e-hailing services, illegal gambling and other economic activities that are not always captured through conventional data collection.

Stats SA estimates that the non-observed economy accounted for 8.7%, equivalent to approximately R551 billion, of South Africa’s total economic activity in 2022.

The agency said the revisions were necessary to ensure that the country’s economic statistics keep pace with changing business practices and developments across different industries.

The revised figures also have implications for how South Africa’s public finances are assessed, particularly the country’s debt-to-GDP ratio. Although the government’s actual debt does not change because of the statistical revision, the larger GDP figure provides a different measurement of debt relative to the economy.

However, the upward revision should not be interpreted as evidence that South Africans have suddenly become wealthier or that the country’s economic challenges have disappeared.

Unemployment, poverty, inequality, weak economic growth and pressure on household finances remain major concerns.

The latest findings nevertheless provide a more comprehensive picture of the South African economy and highlight the importance of accurately measuring economic activity across both formal and informal sectors.
