The US Census Bureau is hiring, so if you need some extra income this might be the perfect job for a genealogist.
I think it could be very interesting to see the process up close and personal and get the inside scoop on census taking. I have known other genealogist who have worked as census takers and they have found the experience useful. However, I don't think it is a job for the faint of heart. If you are interested, time is of the essence. They hope to have everyone hired by May.
