This is a fascinating read.
Grantome.com is a project of data scientists who have generated a database of grant funding information. This particular blog post focuses on a longitudinal analysis of some of the most heavily NIH-funded Universities and other research institutions. It shows those which are maintaining stable levels of support, those in decline and those which are grabbing an increased share of the extramural NIH pie.
The following graph was described thusly:
Each histogram bar represents the range in the percentage of grants that has been held between 1986 and 2013. The current, 2013 level is represented by a black vertical line. Finally, arrows inform on the latest trend in how these values are changing, where their length and direction reflect predictions in the level of funding that each institution will have over the next 3 years. These predictions were made from linear extrapolation of the average rate of change that was observed over the last 3 years.
This serves as an interesting counterpoint to the discussion of the "real problem" at the NIH as it has typically centered around too many awards per PI, too much funding per PI, the existence of soft-money job categories, the overhead rates enjoyed by certain Universities, etc.
I am particularly fascinated by their searchable database, in which you can play around with the funding histories of various institutions. Searches by fiscal year, funding IC are illuminating, as is toggling between total costs and the number of awards on the graphical display.
