Trump citizenship plan will face logistical, legal hurdles

WASHINGTON >> After failing to get his citizenship question on the census, President Donald Trump now says his fallback plan will provide an even more accurate count — determining the citizenship of 90 percent of the population “or more.” But his plan will likely be limited by logistical hurdles and legal restrictions.

Trump wants to distill a massive trove of data across seven government agencies — and possibly across 50 states. It’s far from clear how such varying systems can be mined, combined and compared.

He directed the Commerce Department, which manages the census, to form a working group.

“The logistical barriers are significant, if not insurmountable,” said Paul Light, a senior fellow of Governance Studies at New York University with a long history of research in government reform. “The federal government does not invest, and hasn’t been investing for a long time, in the kind of data systems and recruitment of experts that this kind of database construction would require.”

Trump says he aims to answer how many people are here illegally, though there already are recent estimates , and possibly use such information to divvy up congressional seats based on citizenship. It’s also a way for Trump to show his base that he’s not backing down (even as he’s had to back down) from a battle over the question on his signature topic, immigration.

The administration faced challenges last year when it was tasked by a federal judge with quickly creating a system to track migrant families that had been separated by immigration officials. They found agency systems weren’t compatible.
