There were 6% more advertisements for US science-related positions posted online in June 2013 than in June 2012, following a 22% increase from 2011 to 2012, according to an analysis of 25,000 recruitment sources including LinkedIn and CareerBuilder. The study, released on 31 July by Wanted Analytics in Quebec City, Canada, also found that the number of employers advertising jobs was up slightly in 2013 after a 15.8% increase from 2011 to 2012. The number of academic posts advertised, however, was down 16.5% from 2012. The biggest increases in recruitment were in San Francisco and Los Angeles, California. In both areas, demand rose by almost one-fifth, owing in part to increased hiring at the University of Southern California and at biomedical research firms including Genentech.
