The county also is dependent on blue-collar work. A report from Emsi, a labor-market advisory firm, studied six Rust Belt states — Pennsylvania, Ohio, Indiana, Michigan, Wisconsin, and Minnesota — and found that counties such as Luzerne with a higher-than-average concentration of manufacturing, mining or agriculture jobs were much more likely to back Trump, especially where those jobs were declining. The study estimated that Luzerne County had lost 34 percent of its manufacturing jobs between 2001 and 2016.
