Latest OASPA data shows dramatic growth in OA articles from past decades is plateauing - OASPA

"Growth in the volume of publications from OASPA members has slowed further compared with previous years. The OASPA dataset shows that just over 1.2m articles were published in 2024. This grew by just 1% over 2023, compared with 4% growth the previous year, and significantly lower than the long-term average.Just over 7.5 million articles were published in the period 2000-2024. 2024’s output therefore represents around 16% of the total across all years. The total number of OA articles reported has more than quintupled since 2017 and grown almost 40x since 2011. CC BY in fully OA journals continues to dominate output, accounting for 57% of 2024’s output (although representing a slight fall compared with 60% in 2023). However, beneath the headlines some interesting observations can be made....

The top 3 publishers by volume of output now account for 69% of the OA content in this dataset, up from the previous figure of 54% showing a higher degree of consolidation. Beyond that the picture is similar to last year, whereby the top 10 publishers by volume account for over 90% of the total output represented in this dataset."
