In January, worldsteel announces the annual production figure for the previous year in a press release. This data may be adjusted over the course of the year.
In May/June, worldsteel issues its annual publication titled 'World Steel in Figures' with updated production data.
In November/December, the data may again be subject to revision in the Steel Statistical Yearbook.
To understand why the figure is subject to variation, please read the related answer in this FAQ. worldsteel recommends that the most recent figure be used for any calculations and communications.
The Steel Data Viewer features monthly crude steel production data for the current and previous year. It also features data included in the Steel Statistical Yearbook in excel format (from 2000).
worldsteel collects and reports figures provided by direct sources. Occasionally, the reported figures are not yet final figures, or there is a delay in reporting. As worldsteel publishes monthly data on the 25th of each month, any unverified figures are marked as 'estimates'. Estimated figures are updated in the following month. If no updated figure is provided, the estimated figure remains. If there are many estimates, or if a major steel-producing company delays the release of its figures, worldsteel may wait a day or two before issuing the monthly statistics.
Data from 64 countries are shown in the monthly statistics tables. Some countries do not report monthly figures. The annual figures include all reporting countries, including those that do not provide monthly data.
The Steel Statistical Yearbook shows the annual crude steel production data for the last 10 years. The figures in the yearbook are updated to include the latest available data from the reporting institutions at the time of publication.
As the yearbook usually appears in November/December, the annual crude steel production figure for the latest year will be different from the figure that is published on worldsteel.org in January and/or in the World Steel in Figures, which is published in April/June.
Production data are frequently revised at source. In January, we publish the annual production figure as it is reported to us. The monthly figures may have been revised over the course of the year, so the annual figure is not a sum of the published monthly figures. worldsteel does not provide an up-to-the-minute statistics service.
This is because we round the data in the PDF, which we attached to the press release. For example, annual data of 0.01 and 0.004 can result in 150% growth, even though annual data is shown as zero. We recommend you refer to the numbers in the monthly statistics Excel spreadsheet (link) if you require more detailed data.
For antitrust reasons worldsteel no longer produces a global capacity utilisation ratio. Information on capacity can be found on the OECD website.
