The percentage of women attorneys working in the Pennsylvania offices of the state’s 100 largest law firms has inched up slightly from 2011 to 2012, but the numbers are still lower than some expected.

It has long been noted that women make up smaller percentages of attorney headcount — something even more apparent at the equity partner level — than their male counterparts, despite years of statistics that show women graduating from law school in numbers equal to or just slightly lower than men. That phenomenon seems to have played out in Pennsylvania firms as well, according to numbers reported in Legal affiliate PaLaw 2012.
