The "question" has been put to paper , many times, before.
"There have been 23 decennial censuses since 1790. All but one between 1820 and 2000 asked at least some portion of the population about their citizenship or place of birth. In 2010, the citizenship question was moved to the American Community Survey, which is sent out annually to many American households. "

Exclusive: How John Roberts killed the census citizenship question
Updated 1:33 PM ET, Thu September 12, 2019
Washington (CNN)Chief Justice John Roberts cast the deciding vote against President Donald Trump's attempt to add a citizenship question to the 2020 census, but only after changing his position behind the scenes, sources familiar with the private Supreme Court deliberations tell CNN.
The case was fraught with political consequences. Democrats and civil rights advocates claimed the query would discourage responses to the decennial questionnaire from new immigrants and minorities and affect the balance of power nationwide.
Roberts' action recalled his dramatic switch in the 2012 case that saved President Barack Obama's Affordable Care Act. Once again, the chief, an appointee of President George W. Bush and a reliable conservative, had sided with the liberals as a dispute of immense national significance went down to the wire.
