This is a print on demand edition of a hard to find publication. In the 2010 decennial census, the Census Bureau will attempt to count the total population of the U.S. This includes, as in previous censuses, all U.S. citizens, lawful aliens, and unauthorized aliens. Some have suggested excluding illegal aliens from the census count, in part so that they would not be included in the data used to apportion House seats among the states and determine voting districts within them.
