"The economic sentiment indicator is designed to project the health of the U.S. economy by analyzing coverage of 15 major American newspapers, using a proprietary algorithm to look for positive and negative sentiment about the economy in every article. The ESI is reported on a scale of 0 to 100; higher numbers represent increasingly positive sentiment. Dow Jones selected the 15 newspapers used to compile the indicator because they include extensive original reporting on economic issues. They are also geographically diverse and represent eight of the 10 largest metropolitan areas in the U.S."
