It doesn't matter if you're in outer space -- you still have to fill out the damned census form. According to this article, "A Russian spaceship carrying census forms is on its way to two cosmonauts so they can take part in Russia's first post-Soviet population head-count... Russia's Valery Korzun and Sergei Treshchev on the orbiting International Space Station will fill out the questionnaires and send them back to Earth, joining millions of their land-based compatriots in the exercise planned for October 9-16."
