... And my family and I part of the largest Filipino community in New England ITTL.
I'm guessing that most will flock to Metro Boston as opposed to Queens/Croydon Co. (where many Filipino-Americans live IOTL), given that it is New England's economic heart as opposed to Brooklyn, and the fact that most Filipino-Americans who do stay in the NYC are might elect to stay in
New Jersey.
Boston is a cheaper city, it is the economic hub of the country and flush with jobs. Brooklyn is sort of the neglected sister of New York/Westchester/Northern NJ. The population is high, the economy is (?there?), and the Long Island provincial government is not as generous with unemployment and welfare as Massachusetts Bay is (this is not to say Filipino New Englanders are all poor! Just that it makes more sense economically no matter what your employment status is to live in Massachusetts Bay v Long Island). Long Island really only sticks around because of the ultra-rich/rich suburban folk who want to live close to the NYC area, and don't forget all of those summer homes on the Long Island shore.
If you make £65,000 a year in Brooklyn, you pay £20,136 in direct income taxes alone to the Province of Long Island and the City of Brooklyn. In Boston, that same income means you pay £20,399 in direct income taxes. The difference being is that property taxes in Boston/Massachusetts Bay are much lower than in Long Island. Combined with greater access to social services, a better funded transportation network (The T is
vastly superior to TCMTA service), it just makes Boston a better place.
