New York continues to be a top destination for foreign immigrants. Also, not in past 12 months given COVID, but over the decade there’s a meaningful inflow of young people from other states (domestic migration, if you will) to NYC to start careers in law, finance, media and fashion, which partially offsets the move of older people to lower tax / better weather locales.
Last I knew the outflow was so great even incoming illegals weren’t making up for it.
At least not when the census was taken....
