I just filled out my Census form and I have to say it was fairly painless and simple. The short form (pdf) really only asks about age, ethnicity and other residences. If anyone has a long form (now called the American Community Survey), please let me know your experiences filling that out.
The question concerning residence can be a bit tricky these days with so many people having multiple residences, children who live on their own but visit home frequently and couples who live togetherbut also maintain separate residences.
