Women have made tremendous gains in the law over the last 50 years. More than half of today's U.S. law students are female, as are 47% of law firm associates, according to the American Bar Association. But the centers of power, especially in BigLaw, reveal stalled progress. Equity partners at the richest firms average more than $1 million in compensation each year, as studies like the Am Law 100 and 200 show. The ABA says that only 21% of equity partners are women, as are only 19% of managing partners.
