OpenAlex data validates prior proprietary bibliometric findings on scientific article growth between 2016 and 2022.
Open GitHub ↗Using OpenAlex, researchers found 48.1% cumulative growth (from 3.85M to 5.70M articles) and a fitted exponential rate of 6.9%/yr from 2016 to 2022, aligning closely with Hanson et al.'s prior Scopus-based finding of 47% cumulative growth.
Finding reviewed
Using OpenAlex data over the 2016–2022 window for DOI-indexed articles, cumulative growth was 48.1% (from 3.85M to 5.70M articles) with a fitted exponential rate of 6.9%/yr, comparable to Hanson et al.'s reported 47% cumulative growth using Scopus filtered to WoS-indexed journals.

We use OpenAlex data over the same 2016–2022 window and find comparable cumulative growth (48.1% from 3.85M to 5.70M articles) and a fitted exponential rate of 6.9%/yr
- The OpenAlex dataset provides complete counts over the 2016-2022 window, moving from 3.85M articles in 2016 to 5.70M in 2022.
- The claim appropriately restricts its scope to DOI-indexed articles from OpenAlex over the 2016-2022 window, explicitly acknowledging that absolute corpus sizes differ from Scopus/WoS.
- The study uses the exact same window (2016-2022) as Hanson et al. (2024), applying parallel bibliometric constraints (DOI-indexed articles) to enable comparison against Scopus/WoS data.
