When filling out the 2010 census there are few things to be on the lookout for.
—HOUSEHOLD AND RESIDENCE: These are determined by where people live or sleep most of the time as of April 1. Household members should include babies born on or before April 1, 2010, as well as non-U.S. citizens. The rationale is that cities and states should receive federal money to support everyone who uses their public roads, schools and other programs.
College students who live away from home and U.S. military personnel who live in barracks are tallied in those places.
If you have more than one home, completely fill out the form for your primary residence. For the second home, mark "0'' for number of residents and indicate you live elsewhere. Doing that may help avoid costly visits from a census taker.
For divorced parents who have shared custody of a child, indicate where a child usually lives. If custody is split equally, the child's residence is where he or she is on April 1.
—RACE AND ETHNICITY: If no box exists that describes yourself, or with the level of specificity you prefer, write it in the space marked for "other race." For example, some Caribbean-Americans plan to check the box for "black, African Am., or Negro" and then write in their ancestry. Multiracial people might check several race categories or write in "multiracial," depending on how they self-identify. The labels do make a difference, because census results will be used to redraw congressional districts with racial and ethnic balance.
