I live in a sizeable (rare) new build neighborhood
https://www.liveatnorthbank.com/ about a mile from Center City Philadelphia. It's new construction on an old industrial site (shipyard) with about 900 homes planned. 350 or so are settled, and to date, about 80% of the residents are Asian (probably 60% Chinese, 20% South Asian). I see a lot of out of state plates (NY, NJ in particular but also California, DC, Maryland, Massachusetts, Washington, Arkansas, Georgia). So far I've counted five Google employees among my neighbors who have relocated from CA or NY.
In the Philadelphia suburbs, especially if you are in a newer neighborhood, it will almost definitely be 50+% Asian, with the largest proportion being South Asian, whereas in the city, the largest proportion will be Chinese.
This demographic shift seems to be happening quickly. In Philadelphia proper, there are also ongoing waves of immigration from slavic and Russian speaking countries, but specifically Ukraine, Russia, Khazakstan, Kyrgyzstan, and Georgia. Apparently immigrant resettlement agencies are settling immigrants in neighborhoods they've largely avoided in the past because there is no housing in traditional immigrant areas (namely, NE Philly).
We seem to get a lot of second wave immigrants in Philly as well. That is, immigrants that first settle in NYC but after a few years migrate down to Philadelphia.
