To better understand research software user and developer communities, the PI team of the Conceptualization of the US Research Software Sustainability Institute (URSSI) conducted a survey of research software users and developers. The focus of the survey was to gather information to help identify how to increase the sustainability of research software. To gather a broad range of perspectives, the survey was distributed to 25,000 NSF and 25,000 NIH PIs whose projects involve research software, as well as mailing lists of interested people such as the WSSSPE email list. In addition, the PI team used snowballing by asking people to forward the survey to others who might be interested. This effort is part of the URSSI conceptualization project, which seeks to understand the diverse challenges and barriers that the research software community faces. The survey received 1194 complete or partial responses to the survey. This dataset is the raw data set of the survey responses exported from Qualtrics and anonymized.
