2010 Census
Every 10 years the United States conducts a required census of its population. They are currently preparing for the 2010 census that will account for everyone living at your address as of April 1, 2010. For more details about the process or to understand why it is important for you to take part in the census you can go to http://2010.census.gov/2010census/how/how-we-count.php
By they way, for those geneaology buffs out there this will mean the the data from the 1940 census will become available as the year progresses as data is released after 70 years.
