This study is the third in a series of reports (Considine, et al., 2009 and 2010) documenting the development of the Marcellus Shale and its economic impacts on the Commonwealth of Pennsylvania. This update finds that during 2010 Pennsylvania Marcellus natural gas development generated $11.2 billion in value added or the regional equivalent of gross domestic product, contributed $1.1 billion in state and local tax revenues, and supported nearly 140,000 jobs (see Table ES1).
