Sysadmin Salary Surveys
As part of its ongoing efforts to gain recognition and advancement for system administrators, LISA annually conducts a System Administrator Salary Survey (formerly the SAGE System Administrator Salary Survey). The results are tabulated, analyzed, and presented in PDF format. For a year, the PDF is available only to LISA members and those nonmembers who participated in the survey; after a year, the PDFs become free to all. It's here! Check out the results of the 2011 Sysadmin Salary Survey!
N.B. Surveys before 1999 were unscientific polls, not statistically valid surveys.
