My general understanding is that people were supposed to mail them in by April 15th the same day as tax day.
But according to good Mayor Bloomberg of New York City where I don't live and there for is presumed good as he can pass no laws that personally effect me, we hear:
2010 Census Timeline:
March 15 - 17, 2010 U.S. Census Bureau mails Census forms to households
Mid-March U.S. Census Bureau mails letter in Spanish, Russian, Chinese, Korean, Vietnamese to inform households how to obtain a Census form in those languages
March 22 - 24, 2010 U.S. Census mails reminder postcards
March 28, 2010 U.S. Census Bureau mails second Census form to households in low-response/hard-to-count areas from 2000 Census:
April 1, 2010 CENSUS DAY
April 15, 2010 LAST DAY TO MAIL BACK YOUR CENSUS FORM
May - July 2010 Census takers visit households that did not return a questionnaire by mail.
December 2010 By law, the U.S. Census Bureau delivers population counts to President Obama for apportionment.
March 2011 By law, the U.S. Census Bureau completes delivery of redistricting data to New York.
Rather interesting they conduct the head count up to and through the month of Caesar's Birth!
I haven't had a visit since I published this thread.
So there is plenty of time for them to come calling...
I smell some sequels in the offing here:
How I had milk and cookies with the Census Takers!
How I played horse shoes with the Census Takers!
which are sure to just really drum up interest in the really blockbuster...
How I invited the Census Takers to my Fourth Of July Barbeque....
Lets see if we can get a sneak preview from this one:
Proto: Who all wants pork chops?
Census Taker: I do, I do, and this government cheese tray is delicious by the way!
Proto: Starting the charcoal briquettes now, that cheese is delicious it only cost the taxpayer’s 14,000,000,000,000.00!
Census Taker: Proto oh no the fire in the briquettes has gone out!
Proto: No worries I will put some more lighter fluid on the briquettes.
::squeeze wheeze, squeeze wheeze, squeeze wheeze::
Census Taker: Proto oh no, your out of lighter fluid!
Proto: Oh dear me, we are! How on earth will we ever get the grill going now?
::The Census Taker looks around in desperation and suddenly their face lights up::
Census Taker: Proto, Proto I know, we can use some of these Census Forms!
:roto smiles as heaps of forms are shoveled on top of the briquettes by the poor emaciated Census Worker whose nary seen a meal in months for the meager wagers that they are paid::
Proto: What a brilliant idea! I guess the Census serves an important purpose after all!
