Like Washington, D.C., which has led national literacy rates since 2010, Seattle has owned the number two spot for three consecutive years.
The annual study, which measures literacy of major cities with populations of 250,000 and above, relies on six indicators: number of bookstores, educational attainment, Internet resources, library resources, periodical publishing resources and newspaper circulation.
Seattle ranked especially high when it comes to education attainment, a calculation that involves percentage of adults with a high school diploma or higher and a bachelor's degree or higher. Plano, Texas led the education attainment category.
Overall Seattle fared well in most categories, ranking in the top ten for literacy indicators involving libraries, Internet resources, booksellers and publications.
Yet surprisingly - or not so surprisingly, considering strains on the newspaper industry - Seattle ranked comparatively low in newspaper circulation, coming at spot number 21. Looks like there's always room for improvement.
