Now that April 1 is here the Census forms are due. Remember, a few of the following guidelines:
The census people are NOT coming to your home until May 1 to July 1. Anyone knocking your door now is a potential scam artist. They will arrive if you have NOT filled out your census form and returned it; or have not filled it out correctly.
There are only 10 questions to answer.
They are not to ask for Social Security Numbers, or bank information.
Do not invite them into your home.
They will have a badge, and carry a black bag with US Census Bureau on it.
Check the web site for further details: http://2010.census.gov/2010census/index.php.

Remember the census takers are not coming to your home until after May 1 until July. If you do not fill out the 2010 Census form sent to you, or do not answer all the questions they will be visiting you in person. The form sent should include a postage paid return envelope.
If they are on your door step now, it is a probable scam.

Do I have to talk to the census taker?

Yes. Your participation in the 2010 Census is vital and required by law, (Section 221, of Title 13 of the U.S. Code). However, rather than rely on criminal charges, the Census Bureau is very successful in getting participation by explaining the importance of the questions we ask and how the information benefits our communities.

Your privacy and confidentiality is the priority:

The census taker who collects your information is sworn for life to protect your data under Federal Law Title 13. Those who violate the oath face criminal penalties: Under federal law, the penalty for unlawful disclosure is a fine of up to $250,000 or imprisonment for up to 5 years, or both.
