Good article. As it says, this is the first time the Census has asked that question to everybody. The census bureau may have asked that question as a sample but a sample is not a census.
TRUMP WANTS TO QUESTION CITIZENSHIP ON THE UPCOMING CENSUS. THIS IS EVEN MORE PROOF THAT HE'S A RACIST!!! ASIDE FROM THE 1960 CENSUS, THE CENSUS HAS ASKED ABOUT CITIZENSHIP IN SOME FORM SINCE 1890.
