Many urban areas in the United States continue to add population to their respective locales by serving as gateway communities for the millions of immigrants who come to live in the country every year. This recent report published by the Brookings Institution, and authored by Audrey Singer, demonstrates a rather intriguing pattern by which certain cities (such as Chicago and San Francisco) have effectively served as immigrant conduits for over a century; whereas other American conurbations, such as Cleveland, were only able to garner large streams of immigrants in the early 20th century. The 36-page report discusses the nature of both former gateway cities as well as drawing on Census 2000 data to look at the emergence of new immigrant gateway cities such as Atlanta, Dallas, and Washington, DC. The report also reveals several other notable findings, such as the fact that by 2000 more immigrants in metropolitan areas lived in suburbs than cities, and their growth rates there exceeded those in the cities.
