Pew is committed to generating research, providing technical assistance, and building relationships to advance powerful, positive change. Whether advancing environmental conservation, examining the impact of government policies on taxpayers and communities, or providing information about relevant trends in society, the foundation of our work is careful planning; a consistent focus on facts, science and data; strong partnerships; and a commitment to stewardship, innovation, and measurable results.

Our work includes a diverse portfolio of projects designed to serve the public and achieve measurable results. They include:

Science and Research

Pew is a data-driven, results-oriented organization. Sound data and the best available science are fundamental to all of our work, and rigorous, nonpartisan, and evidence-based research informs the design and implementation of our efforts. Research projects include data analysis, public opinion surveys, conservation science, support for biomedical and marine research, and initiatives focused on our Philadelphia hometown.


We work in close collaboration with philanthropists and organizations that share our commitment to independent research, measurable results, and public service. We value our partners and benefit from their support. These diverse individuals and organizations bring resources, energy, and expertise to Pew; provide new perspectives and insights as our work moves forward; and offer valuable lessons for solving problems.

Technical Assistance

Pew provides technical assistance to help nonprofit organizations, businesses, and governments make evidence-based policy decisions. We analyze data, develop implementation plans, tailor models to the specific needs of the organizations with which we work, monitor progress, and help interpret results.


For some initiatives, we combine research and policy work with strong and carefully planned advocacy campaigns. We design innovative policy solutions, build coalitions, and help diverse stakeholders find common ground. Pew experts regularly testify about critical issues before Congress, state legislatures, and international bodies and help bring credible voices into policy debates.
