The Washington Post has recently launched this site, which will be the home for a series of occasional articles about racial and ethnic divisions in the US. The first article in the series, "One Nation, Indivisible: Is it History?" by William Booth, is currently featured. The article discusses the "second great wave of immigration" into America, which greatly differs from the first wave of European immigration in that it is mostly fueled by Asian and Latin American immigrants. The site contains selected ethnic shift graphs and charts, a link to a WP article on US immigration policy, and a link to selected US Census data.
