The number of women in the computer systems group and in the executive group more than doubled between 1995 and 2006. [...] The majority of the occupations listed above can in general be found in the following occupational categories defined in the CPA: scientific and professional; computer systems; program and administrative executive; and administrative and foreign service categories. [...] In fact, there are now more women than men in both knowledge-based and less knowledge-based occupations; this mirrors the general increase in the number of women in the CPA between 1995 and 2006. [...] In the case of knowledge-based workers, the shift was due to an increase in women while in the case of less knowledge-based workers, it was due to a decline in men in the CPA. [...] As the number of women increased in all categories of knowledge-based occupations, in 2006 women outnumbered men in two categories: the program and administrative group and the administrative and foreign services group.
