According to a recent survey in Science (http://sciencecareers.sciencemag.org/ career_development/previous_issues/articles/2006_11_03/ life_scientists_report_rising_salaries_and_high_job_satisfaction/), on average, life science PhDs working in industry made $116,000 last year—up 10% over 2005. Median salaries, which filter out the extremes, are more modest: for doctorate-level scientists working in biotech, a salary of $100,000 falls around the middle of the pack (almost one-third higher than in 2001). Globally, >130,000 R&D staff work in biotech and 200,000 people are employed in research and business capacities at public biotech companies.
