If you are a US-based company but have a sizeable contingent of Asian lawyers, do they count toward your diversity goals? I suppose not, because the idea of diversity is to have people of different attributes mixed in the same place.
Even with that, however, it must be complicated to decide if employees who are in the majority in one location will be treated as minorities in another location. Would the sole Caucasian lawyer on the Japanese legal team alter the diversity metrics of the law department (See my post of June 17, 2008: diversity with 29 references.)?
