The Newest New Yorkers: Characteristics of the City's Foreign-born Population (2013 edition) provides a comprehensive portrait of immigrants in New York City. It examines where the city's foreign-born come from, their patterns of settlement, the demographic and socioeconomic characteristics of the city's immigrants, the role of the foreign-born in the New York region, changes in the legal paths of entry of newly admitted immigrants, and concludes by examining the impact of immigrants on the city. This is the latest volume in The Newest New Yorker series, which began in 1992 with the publication of The Newest New Yorkers: An Analysis of Immigration to New York City in the 1980s, and continued with The Newest New Yorkers, 1990-1994, The Newest New Yorkers, 1995-1996, and The Newest New Yorkers, 2000, which was released in 2005. The 2013 edition of The Newest New Yorkers builds on the preceding volume and provides detailed analyses of the latest available data. It continues a tradition of providing comprehensive information on the foreign-born to policy makers, program planners, and service providers, to help them gain perspective on a population that continues to reshape the city. And for the fi rst time, this edition includes interactive web content, at www.nyc.gov/population. New York City's demography is dynamic, defi ned by the ebb and fl ow of people. These demographic changes result in a unique level of diversity: over one-third of the city's 3 million foreign-born residents arrived in the U.S. in 2000 or later; 49 percent of the population speaks a language other than English at home; and in just 30 years, what was a city with a population of primarily European origins has now become a place with no dominant race/ethnic or nationality group. Indeed, New York's unmatched diversity epitomizes the world city.
