From the NIH RePORT Website, check out the Funding Facts BETA tool under Quick Links. This tool allows you to run detailed reports of NIH funding-related data in a matter of clicks.
You can search for NIH funding by various budget mechanisms, dollars awarded by specific activity codes during a particular fiscal year, or application success rates, to name but a few possibilities. A user-friendly search interface lets you specify search criteria for six categories: Topic, Institute/Center, Funding Mechanism, Activity, Type, and/or Fiscal Year.
Please note, it is important to remember that this site is currently in beta mode, so the data are being checked and changes will occur.
