Is there any publicly accessible information regarding the success rate of grant/project applications for science/technology and other research grant programs (e.g. NSF grants) and its variation over time?
I'm not interested in an exhaustive list but some illustrative examples would be much appreciated.
It's surprisingly hard to find that information, I was expecting to get it more easily, in particular when public funding is involved. I've found for the European Union FP7-ICT call 1, there were 1836 proposals for only 318 accepted, with a total 1.2 billion euros funded (Source, slide 18).
I guess a good strategy could be to contact the Research Division of the European Commission, I'm sure they have this information somewhere, and they are probably able to provide it.
