Law firms are making progress — slow progress, but progress nevertheless — when it comes to boosting women and attorneys of color to partner.

Nationally, from 1991 to 1998, the proportion of women partners in the largest U.S. firms — those with more than 250 attorneys — increased from 10.9 percent to 14.7 percent. During the same time, the proportion of minority partners increased from 2.4 percent to 4 percent, according to a National Association for Law Placement survey, “Perceptions of Partnership: The Allure and Accessibility of the Brass Ring.”
