Of note is that the Census starts today and when you respond you are supposed to respond about where you will be living on April 1.
If you have a child that is away at college and that school has not sent people home, you will fill out the survey without that child, as he or she is supposed to be counted in the city in which their college is located.
If, after you fill in the survey, the college goes online-only and sends students home and does so before April 1, what do you do?
