In a nation that includes, amongst other cities, New York City, this is extremely unlikely.
New York was famously segregated by Robert Moses. It’s up there on the list due to being a welcoming and diverse destination today, but those policies of the past can be felt today, long after they are gone.
It's worth taking a look at their methodology and how they're measuring diversity. Notably, NYC ranks much higher than Houston for cultural diversity (#5 vs #28 for Houston).
But the fact that Houston is even in the list in the first place is the interesting part. Whether it beats NYC or not is sorta not the most important part of my comment.
It seems the Forrest might have been missed for the trees. (I don’t feel like you understood or validated what I said, whether you disagree with the precise methodology or not)
Home prices are dropping like a rock. And commute times were hell a decade ago.
I think the bigger issue is that these firms bet big on real estate and then the pandemic suddenly clued people in that remote work was possible and now instead of admitting they made a mistake are blaming the issue “on Austin.”
Also: to speak to the diversity part. Read up on Austin’s 1928 plan to intentionally segregate the city. Austin is still one of the most racially segregated. In an interesting turn of events Houston (due to its lack of zoning laws making redlining hard to impossible) is the most racially diverse city in the nation. Amazing what impact a bunch of people a hundred years ago can have on a place even after they are dead and their laws changed.
