With the U.S. Census process beginning, the Better Business Bureau (BBB) advises people to be cooperative, but cautious, so as not to become a victim of fraud or identity theft.  If a U.S. Census worker knocks on your door, they will have a badge, a handheld device, a Census Bureau canvas bag, and a confidentiality notice. Ask to see their identification and their badge before answering their questions.  For further precautions and information: 2010 Census Cautions.
