JAMA: impact and ranking
JAMA has a 2-year mean citedness of 9.53 in OpenAlex, which ranks #427 of 18,122 journals, and an h-index of 1,011. This is the open counterpart of the impact factor, not Clarivate's figure. All journals.

What is the impact factor of JAMA?
The impact factor is a figure Clarivate licenses, so it is not shown here. Its open counterpart is the 2-year mean citedness OpenAlex holds for JAMA: 9.53, the mean number of citations received by the journal's papers of the last two years. That ranks JAMA #427 of 18,122 journals, in the top 2%. The two figures follow the same idea on different records, so they are not equal.
What is the h-index of JAMA?
OpenAlex gives JAMA an h-index of 1,011: 1,011 of its papers have each been cited at least 1,011 times. That ranks #8 of 18,122 journals.
How much does JAMA publish?

How these figures are made
Every figure is from OpenAlex's record of this journal, snapshot of 2026-10-14. The 2-year mean citedness is not Clarivate's impact factor: it counts the citations OpenAlex has recorded, so it differs from the licensed figure. Ranks are among the 18,122 journals with at least 1,000 works in OpenAlex and a record in 2025 or later that pass checks for record errors. Method and limits.
