This group includes members as disparate as West Africans in the South Bronx, Hasidic Jews in Brooklyn and Bangladeshi in Queens, who are united by their inability to afford the high prices for large market-rate rentals and their inability to find publicly subsidized alternatives even as the overall housing stock has swelled.
