Results of Sigma Xi's survey of 7600 postdocs at 46 US institutions. Very interesting discussion of salaries, training, and administrative oversight.

NSF Issue Brief, November, 1998. "By 1995, about one-third of the 1993 postdocs had found academic employment. However, only 12 percent were in tenure track positions at 4-year colleges or universities, a rate that varies little across five of the six major postdoc fields (the exception was agricultural sciences with 6 percent). Another 21 percent had appointments ranging from low-pay adjunct teaching positions to somewhat better paying jobs with research or administrative responsibilities. Industrial employment was reported by 17 percent; the remainder was in Government or nonprofit sectors. Fewer than 2 percent were unemployed, and only a small number—3 percent—reported that they were employed in a job unrelated to their degree because a job related to their degree was not available."

NSF Issue Brief 99-310. "This issue brief examines the self-reported postdoc histories of holders of science and engineering Ph.D.s from U.S. schools to address the question whether the use of postdocs has changed."
