Women are woefully underrepresented in IT in general, and programmin and other higher-level IT areas in particular. Further, this is not merely a United States problem, but is worldwide: with few exceptions, women represent less than 30% of the IT workforce, primarily in the lower-skill areas, while comprising approximately half of the workforce. Even worse, the rate of undergraduate admission of women to CS majors has been trending downward. This deplorable situation has many causal factors, and has been studied extensively since the 1980s, yet the underlying causes are not clear. No single presentation can address all the factors, or all aspects, from K-12 to university undergraduate and graduate studies, to job and career development and retention. This presentation will focus primarily (but not exclusively) on entry to IT.
