New York City is the largest city in the United States.

This fact, therefore, necessitates a keen study of its demographics if one is to clearly understand the way its population plays on its importance and notability as one of the metropolises of the US. The city had a population of 19,745, 289 as of 2016, which was approximately 6% of the national population that is 325,423, 956 ("US Population," 2017). However, as of today, the population density of the United States is 92 persons per square mile, while that of New York is approximately 411.2 persons per square mile (Bureau U.

, 2017). Thus, while the city accounts for less than 6% of the population, its density is over four times that of the nation. Perhaps, this explains why it has the highest racial and ethnic diversity in the US, and it is the country's most cosmopolitan urban space. The ethnic ratios for New York are 70% white, 15% African-American, 8% Asian, 5% Latino/Hispanic, 1% Native Indian, and 1% Other (Bureau U., 2017). These ratios match the national figures more or less, except for the African American and Latino/Hispanic percentages, which are higher in the southern region.

;As for the population composition by age, the median age in the United States is 38 years. However, 21.3% of the persons in New York are 18 and below, which brings the average age of the city significantly below the national one (Bureau, 2017; "US Population," 2017). More specifically, while there may not be research directly stating it, the relatively lower median age may be a point of reference if one is trying to explain the higher rates of youth unemployment in the city. Markedly, of the 19 million people in New York, about 51.4% are female and 48.

6% male. Again, these ratios are strikingly close to the national average.;References;Bureau, U. (2017).
