Everything you're saying here is reasonable/plausible. But it's not at all what the linked article says; it says that there was 40% turn-over of people leaving and entering the city, which is absurd. The first sentence is literally "Millions of people have moved out of New York City during the pandemic, but at the same time, millions of others with lower incomes have taken their place". Not moved within the city, moved out of the city, and being replaced by other lower-income people. That is all completely made up and wrong. I'm not misrepresenting you; rather, you're misrepresenting the article. The article is indefensibly wrong.
