Eg, in some parts of public health research and medicine you get your name on a paper by being the source of the data, whether you do any work or not.
Alternatively, you might put your name on everything any grad student in your lab produces.
There are also field-specific effects which push numbers up or down: it is easy to publish in medicine since there are so many journals and many do not have high standards (some do, but many do more).
In good journals in economics it is not uncommon for papers to spend years in the referee process so total publication numbers are low. (Bad journals in economics have much lower standards.)

Varies a lot by field.
