> The notion of these counts ever being used for enforcement — basically targeting high population, low citizenship-count blocks for ICE raids or whatever — that would be really, really problematic.
Stepping back, think in general about a government that wants to target, arrest, and deport certain groups of people, that is also going door to door and trying to establish records of who everyone is and where they live. Because of the bad optics of this, the US census has traditionally been extremely independent from law enforcement. The government has recently been attacking this barrier e.g. with the citizenship question and other things discussed in the article. Historically speaking, you might argue marginalized groups in such scenarios would be foolish to trust the census.
