not that I disagree with most of the comments here, but the census is mandated by the Constitution. The explicit use of the Census is to distribute the number of representatives geographically, but its also the best tool the government has to make policy decisions regarding how to distribute, plan, budget, forecast, for various government programs, from telecommunications licensing and land development to, yes, planning for future sanitation projects.
The government doesn't care if you crap in the woods in your back yard or your john, but they would like to know if enough people are using plumbing to predict the amount of demand people will have on public utilities.
