紐育のチャイナタウンにおける言語変動。広東語の衰退とマンダリンの興隆。
それは北米への中国人移民の出身地の変化によるもの。広東人から1990年代以降は福建人が主流に；
Cantonese, a dialect from southern China that has dominated the Chinatowns of North America for decades, is being rapidly swept aside by Mandarin, the national language of China and the lingua franca of most of the latest Chinese immigrants.The change can be heard in the neighborhood’s lively restaurants and solemn church services, in parks, street markets and language schools. It has been accelerated by Chinese-American parents, including many who speak Cantonese at home, as they press their children to learn Mandarin for the advantages it could bring as China’s influence grows in the world.
But the eclipse of Cantonese — in New York, China and around the world — has become a challenge for older people who speak only that dialect and face increasing isolation unless they learn Mandarin or English. Though Cantonese and Mandarin share nearly all the same written characters, the pronunciations are vastly different; when spoken, Mandarin may be incomprehensible to a Cantonese speaker, and vice versa.

In North America, its rise also reflects a major shift in immigration. For much of the last century, most Chinese living in the United States and Canada traced their ancestry to a region in the Pearl River Delta that included the district of Taishan*1. They spoke the Taishanese dialect, which is derived from and somewhat similar to Cantonese.Immigration reform in 1965 opened the door to a huge influx of Cantonese speakers from Hong Kong, and Cantonese became the dominant tongue. But since the 1990s, the vast majority of new Chinese immigrants have come from mainland China, especially Fujian Province, and tend to speak Mandarin along with their regional dialects.
In New York, many Mandarin speakers have flocked to Sunset Park, Brooklyn, and Flushing, Queens, which now rivals Chinatown as a center of Chinese-American business and political might, as well as culture and cuisine. In Chinatown, most of the newer immigrants have settled outside the historic core west of the Bowery, clustering instead around East Broadway.
