True. The funny thing is that many of the immigrants are not settling in central cities, but in older suburbs (or in garden apartments out in the exurbs).
True. It is happening more and more in the DC metro area. Housing is cheaper the further out you go, which is why many immigrants settle in the suburbs or exburbs. Commuting is getting to be more and more undesireable as the roads and mass transit become clogged, expensive, and time consuming. Gentrification of DC is ongoing. The main thing is where the jobs are located.
