Data and Methodology

The data available on this website include contributions of $100 or more to candidates and political committees in Pennsylvania from 1/1/2001 to 6/7/2010 (Cycle 3, 2010).  The data include contributions recorded by the Pennsylvania Department of State (DOS) but do not include contributions to candidates for local, municipal, and other offices who were not required to file contribution reports with the DOS during this time.

Contributions included in this dataset are limited to those made by the political action committees (PACs) of companies (or their parent companies) with a profit interest in Marcellus Shale drilling and those made by executives of these companies.  Contributions made by lower level employees were not included.
