From Andrew Gelman's Statistics Blog
http://www.stat.columbia.edu/~cook/movabletype/mlm/ Statistical Modeling, Causal Inference, and Social Science] is statistcs Blog. It is primarily written by Andrew Gelman, a professor in the Departments of Statistics and Political Science at Columbia University.
In a July 1,2005 posting Andrew continues an earlier discussion on mispercetion of minorities and minorities. This earlier discussion was inspired by a note from Tyler Cowen reporting that the March Harper's Index includes the statement:
-Average percentage of UK population that Britons believe to be immigrants: 21
-Actual percentage: 8%
This reminded Andrew of an article in the Washington Post by Richard Moral (October 8, 1995) in which he discussed the results of a Post/Keiser/Harvard servey "Four Americas: Government and Social Policy Through the Eyes of America's Multi-racial and Multi-ethnic Society"
