Is there any institution or report tracking academic fields in terms of funding (today and historically)?
Two platforms come to my mind.
First, Dimensions offers detailed data about grants and research funding - however, only the paid version would allow users to delve deeper into these data so as to treck trends over time (including at the level of countries, disciplines, topics, institutions or individual researchers).
Second, wizdom.ai seems to allow you to track funding allocations by research topics for free, including a list of &quot;top funders&quot;, a &quot;funders analysis&quot; containing the amount of money allocated, a topic wordcloud, and a timeline.
Here is an example for Robotics: https://www.wizdom.ai/topic/robotics/funders/20903754, and a screenshot of how it looks like:
