The Economic and Social Research Council (ESRC) defines research impact as the demonstrable contribution that excellent research makes to society and the economy.
This can include both:
The National Institutes of Health defines research impact as “advances that improve health, revolutionize science, and serve society more broadly.”
The National Science Foundation funds scientists and engineers to perform research that advances discovery and innovation. The agency also expects researchers' work to have broader impacts: the potential to benefit society and contribute to the achievement of specific, desired societal outcomes.
