<p>I’ll be inclined to believe that we have reached the % of women in science and engineering that corresponds to their actual interest level (i.e., % of women among all those who are seriously interested in science and engineering = % of women who are actually in science and engineering) when the numbers stop changing. They are still changing now.</p>
<p>For example, at [nsf.gov</a> - SRS S&E Doctorate Awards - US National Science Foundation (NSF)](<a href=“http://www.nsf.gov/statistics/doctorates]nsf.gov”>Doctorate Recipients from U.S. Universities | NCSES | NSF), you can find statistical tables on the Ph.D. degrees awarded in science and engineering. The online tables cover 1994 to 2005 (full), with brief data for 2006, due to the time lags in data collection and processing. The 1994 tables provide data back to 1985. The % of Ph.D.s going to women in various fields is increasing over time. For example, in astronomy, women earned 15.9 % of Ph.D.s in 1985, 20.8 % in 1994 and 26.3% in 2005. In chemistry, women earned 19.7% of Ph.D.s in 1985, 27.7% in 1994, and 34.0% in 2005. In physics, women earned 9.3% of Ph.D.s in 1985, 11.3% in 1994, and 15.0% in 2005. For other fields, see the tables.</p>
<p>The representation of women on university faculties is generally lower than the % of Ph.D. recipients. Part of this is the time lag (post-Ph.D.) to become a faculty member, part of it is the turnover rate for the faculties, part of it may be differences in the % of women Ph.D.s among US citizens and permanent residents vs. non-citizens who return home. However, the % of women faculty members still seems to be a bit lower than might be predicted: For example, the American Chemical Society frequently publishes reports (in the magazine Chemical and Engineering News) on the number of women faculty members in the top 50 or top 100 chemistry departments in research universities in the US (with the rankings based on federal research expenditures in the departments). Currently it’s running at roughly 15% women overall, not depending too much on whether the top 50 or top 100 departments are considered. The representation of women is slightly higher at the lower faculty ranks (younger faculty) than at the higher ranks. The % of women faculty also is rising.</p>
<p>With the longitudinal view, you can be pretty sure that something was discouraging women in the past, although you won’t have a numerical handle on the situation in 2008 until about 2018.</p>
<p>Yes, there has been a problem for women in science and engineering.</p>
<p>Yes, I think there is also a problem of a different nature for young men, especially at the pre-college level. An acquaintance of mine had a bright son in a rural elementary school. His teacher complained that he asked questions to which she didn’t know the answer. He actually had an “educational plan,” which included the “goal” that he would not ask a question unless the answer was given in the textbook. (Yes, you did actually read that right, if it seems very strange.) High school graduation rates also indicate a problem, disfavoring boys.</p>
<p>But I don’t think it’s really either/or, help young men or help young women, because they encounter problems at different stages of education, and different people should be addressing the different problems.</p>
