Salary Survey Methodology

The survey was conducted via a web-based survey which was open from February 15 to June 2, 2008. Participation in the survey was promoted by e-mail and advertising to readers of The Scientist and visitors to The Scientist web site. It was also promoted by participating scientific societies to their members. Usable responses were received from 4,702 individuals in the United States. Since many individuals are subscribers to The Scientist, and/or registrants on their web site, and/or members of one or more of the sponsoring societies, it is not possible to compute an accurate rate of response.
