Kept saying this "The Census Bureau, which falls under the Commerce Department, has long favored using administrative records -- including data from the Social Security Administration, IRS, US Citizenship and Immigration Services and the State Department -- to gather citizenship data, rather than asking individuals to self-report their status on the census itself.". Any person that does research known that self reported data about a topic like this would be unreliable. The government already has this data. No need to gather anything other than to want to affect minorities.
