What does the h-index actually measure?+
The h-index is the largest number h such that a researcher has at least h papers each cited at least h times. It balances productivity and impact together, rather than measuring either in isolation, so a researcher can't inflate it with many low-impact papers or a single highly-cited one.
Why would I want to calculate the citation threshold needed for a target h-index?+
Working backward from a target h-index tells you how many papers need a given citation count to reach that milestone, useful for researchers tracking progress toward tenure, grant, or promotion benchmarks that reference specific h-index values.
Does publishing more papers always increase h-index?+
Only if those new papers accumulate enough citations; publishing many uncited or lightly-cited papers doesn't raise the h-index at all, since each contributing paper must individually meet the citation threshold. Quality and reach matter more than sheer volume.
Is the h-index comparable across different academic fields?+
No, citation practices vary enormously by field: fast-moving fields like biomedical research have far higher typical citation counts than mathematics or history, so h-index values should only be compared within the same discipline and career stage.
Can the h-index decrease over time?+
In practice almost never, since it's based on cumulative citation counts that only grow, but it can effectively stagnate if a researcher stops publishing or their older papers stop attracting new citations relative to peers who continue advancing.
