The stereotype of a New Yorker is someone who is hurried and inattentive, who considers every tourist a hick, but the truth is that New York has it all. A New Yorker can indeed be grumpy while another can be extremely friendly. In fact, in New York it is 
possible to encounter every imaginable type of human being.New Yorkers
New Yorkers, or new yorkers, like the inhabitants of certain other large cities in the U.S., are part of the most educated, critical, and cosmopolitan segment of the American population. About 64% of its residents are “natives”; the rest were born abroad.Racial Salad
With approximately 20 million inhabitants in its metropolitan area, the Big Apple is a racial salad. Its white population (37%) constitutes the main ethnic group, but New York is also inhabited by Hispanics (27%), non-Hispanic blacks (26%), and Asians (10%). This proportion varies with the waves of immigration; New York is the second U.S. city that receives the most foreigners, after Los Angeles.The Concept of Ethnicity and Race Among Americans
Americans tend to use a classification that considers nationality and geographic origin more than “race.” Those of European descent and “white” individuals of European nationality are called “whites.” Latin Americans in general are referred to as “Hispanics,” including us Brazilians, who do not speak Spanish. But try explaining that you are not Hispanic! While many New Yorkers know perfectly well what a “Brazilian” is, most Americans, especially in the Midwest, have a vague idea that we descend from the same Latinopithecus ancestor as Hispanics and that we inhabit some Caribbean island infested with monkeys and alligators.“Blacks” Only Afro-descendants Born in the U.S.
The classification “blacks” applies only to African Americans, including mixed-race individuals; black and mulatto Latin Americans are considered “Hispanics,” just like Gisele Bündchen. On the other hand, two black individuals, one “American” and one Cuban, would be in different categories.
Immigrants tend to concentrate in certain regions based on their origin: there is an Irish neighborhood, an Italian one, a Chinese one, a Puerto Rican one, etc. Little Brazil, however, is not a “Brazilian neighborhood” but a street. 46th Street. There, there is a diverse commerce, Brazilian bars and restaurants, a Brazilian travel agency, but few compatriots live there.The Rivalry Between New York and Boston
There is a folkloric rivalry between New York and Boston, a city in the State of Massachusetts, especially in baseball (the Red Sox and the NY Yankees are mortal enemies!). The Bostonian, who considers himself an heir to British elegance, views the New Yorker as an impolite being who only thinks about chasing money. The New Yorker, in turn, thinks the people from Boston are pretentious. This healthy cultural dispute passes through each generation.Source: www.manualdoturista.com.br
