Dr. John W. Miller, President Emeritus of Central Connecticut State University conducted annual studies aimed at identifying America's most literate cities. Miller drew from a number of available data resources. The CCSU America's Most Literate Cities study ranks the largest cities (population 250,000 and above) in the United States. The study focuses on six indicators of literacy: newspaper circulation, number of bookstores, library resources, periodical-publishing resources, educational attainment, and Internet resources.
