The dialect is spoken by people in the Northeastern part of Mainland China; areas like Liaoning (except its southern part from Dalian to Dandong where Jiao Liao Mandarin is spoken), Jilin, and Heilongjiang provinces. With over 100 million people living in the Northeastern part of China, the Northeastern Mandarin-speaking population is quite large. Like other Mandarin dialects, differences between Northeastern Mandarin and other forms arise from the wide geographical distribution and cultural diversity of northern China. Overseas, Northeastern Mandarin is being spoken in increasingly larger communities in the Chinatowns of New York City in the United States.
Northeastern Mandarin can be subdivided into regional sub-dialects named for major cities where there might be slight differences.
