The Guardian has a helpful entry in its series on careers: "What to do with a degree in anthropology."
Most don't pursue graduate work:
Of the anthropology graduates who left university in 2008, 51% were in employment after six months in a diverse range of careers such as advertising and sales (8%), business and finance (6%) and public or private sector management (12%). However, a large number were working in catering (15%) or in clerical roles (20%) – no doubt a reflection of the current scarcity of graduate-level jobs.
I think there is no degree that articulates so well with a broad range of other fields -- there are ways to combine anthropology with everything from history to engineering. That's one reason why graduates have such a broad range of careers, they're led by their interests in other fields as well.
