the nds quantified the degree to which women and minorities are underrepresented on science and engineering faculties at research universities. because the surveys were complete populations and disaggregated, the degree of underrepresentation was revealed, in ways it had never been revealed previously. for example, the fy 2002 survey showed that there were no black, hispanic, or native american tenured or tenure track women faculty in the top 50 computer science departments. it also revealed that there were no black or native american assistant professors in the top 50 chemistry departments. analogous surveys were carried out for top 100 departments in each of 15 science and engineering disciplines in fiscal years (fy) 2005, 2007 and 2012.
