Didn’t the previous admin intentionally try to undercount the people in this state by excluding undocumented people?
Trump’s plan was to exclude unlawful residents from reapportionment of congressional districts, and give states the option to exclude them from redistricting. It was not to have the census not count them at all.
The effect of the former would be to give rust belt states about 9 more House seats and electoral votes at the expense of CA/TX/NY/FL/NJ. The effect of the latter would be to have more state legislative seats in white and black neighborhoods and fewer in hispanic and asian areas. The states that would have both implemented it, and where it would have had a major effect, is mostly TX and GA.
