<br /> The US Constitution requires a census of "population" — not citizens.<br />It says "persons" — not "citizens" or "green card holders."<br />That's why the Trump admin's new citizenship question has such intense opposition.<br />It may deter participation and lead to an inaccurate population count.<br />Federal law provides immunity for those answering census questions.<br />Census reports can't be admitted as evidence or used in any action or proceeding. <br />
