Each year, OASPA compiles a dataset of open access publishing output and
openly shares the data. We are delighted to once again have worked with
Delta Think who have helped us by taking on the analysis, structuring and
presentation of the data we most recently collected.

This blog post
<https://www.oaspa.org/news/latest-oaspa-data-shows-dramatic-growth-in-oa-articles-from-past-decades-is-plateauing/>
published today highlights our findings which showed that growth in the
volume of publications from OASPA members in 2024 slowed further compared
with previous years, and is significantly lower than the long term average. As
we saw last year, there is a drop in total output across fully OA journals,
although hybrid OA content continues to show stronger growth and makes up
the shortfall.

Please feel free to use and share the data. This post is a volumetric
analysis about the quantity of open access journal outputs, and we know
this is not the whole story in open access publishing. Do please get in
touch with questions, comments or suggestions about other helpful
indicators of progress and evolution in open access today.

Best wishes,
Bernie
