"This report was produced by the Pew Research Center and aims at understanding the news ecology of three distinct metropolitan areas in the United States: Denver, Colorado; Macon, Georgia; and Sioux City, Iowa. Data in this report are drawn from separate analyses, each with its own methodology: a survey conducted July 8-August 18, 2014, among a representative sample of adult residents in each city; an analysis of news content; an audit of local news providers; interviews with individuals in each community from local government, civic life, business, academia and journalism and a social media analysis."
