Teacher: Now, understand the problem? Solve this instance: Question: How many people of Chinese origin lived in New York the year the Chinese Exclusion Act went into effect? Passage:The first Chinese immigrants came to lower Manhattan around 1870, looking for the "gold" America had to offer. By 1880, the enclave around Five Points was estimated to have from 200 to as many as 1,100 members. However, the Chinese Exclusion Act, which went into effect in 1882, caused an abrupt decline in the number of Chinese who immigrated to New York and the rest of the United States. Later, in 1943, the Chinese were given a small quota, and the community's population gradually increased until 1968, when the quota was lifted and the Chinese American population skyrocketed. Today, the Manhattan Chinatown () is home to the largest concentration of Chinese people in the Western Hemisphere and is one of the oldest ethnic Chinese enclaves outside of Asia. Within Manhattan's expanding Chinatown lies a "Little Fuzhou" on East Broadway and surrounding streets, occupied predominantly by immigrants from the Fujian Province of Mainland China. Areas surrounding the "Little Fuzhou" consist mostly of Cantonese immigrants from Guangdong Province, the earlier Chinese settlers, and in some areas moderately of Cantonese immigrants. In the past few years, however, the Cantonese dialect that has dominated Chinatown 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 energy and population of Manhattan's Chinatown are fueled by relentless, massive immigration from Mainland China, both legal and illegal in origin, propagated in large part by New York's high density, extensive mass transit system, and huge economic marketplace.
