Gender and Academia — Some Data from The Physics Field:

Inside Higher Ed has a story on a new report about women in physics teaching:

  Physics is among the most male-dominated of disciplines. And while commentators bandy about many possible causes — discrimination, the lifestyle tradeoffs required by graduate school or the academic workplace, and, controversially, innate aptitude — the problem seems most directly attributable to female students abandoning physics in droves between high school and college.
  So concludes a report issued by the American Institute of Physics, which found that the relatively small proportion of female faculty members in the field occurs not because of a “leaking” pipeline within academe, but because of the small proportion of women who choose to study physics after 12th grade.

The report is available here.
