The RSAI is pleased to announce that the 2009 ISI Impact Factor data has been released and we are delighted to report that the Impact factor for Papers in Regional Science (PIRS) has increased from 1.259 to 1.397, placing the journal 23/61 in the Geography category, (vs 23 of 51 in 2008). PIRS is also now ranked 22/66 in the Environmental Studies category and 21/95 in the Public, Environmental & Occupational Health category. As you can see, the geography category has grown for 2009, and so the result for Geography is all the more impressive.This is a great result - congratulations to all the production team, especially Jouke van Dijk and his editors!
