For years, firm leaders in Washington have struggled to increase diversity among their lawyer ranks — and with headcounts down across the region, the effort has only become more difficult, they say.

This year’s Legal Times 150, our annual survey of headcount at Washington-area law offices, showed that, of the 702 area lawyers who lost their jobs during the past year, almost half were women. And minority lawyers accounted for 101 of the slots. Overall, women accounted for about one-third of the lawyers at the 150 largest law offices and minorities 13%.
