Policymakers require timely, accurate, evidence-based research as soon as it's available. Further, statistical agencies need information about techniques and survey practices that yield valid and reliable data. To better meet these needs, Mathematica Policy Research recently launched a working paper series offering policymakers and researchers access to our most current work.

The series launched with three working papers and will release future papers as they are ready on a regular basis. It will feature cutting-edge research from our health, human services, and survey and statistical experts on compelling issues across Mathematica's diverse topic areas. In addition to providing access to our most current work, the working papers will share some of the in-depth analyses behind our other publications. The papers are intended to encourage discussion before final peer review and possible publication. In keeping with Mathematica's high standards of quality, all working papers undergo a rigorous internal quality review.

This book, which can be downloaded free of charge, is a comprehensive overview of the physical and mental heath needs, relationships with adult children, and social issues of our population over age 50. It is edited by award winning writer Gloria Hochman. (SaraKay Smullens, CFLE, wrote the chapter on Friendship.)

The Pew Research Center is a nonpartisan "fact tank" that provides information on the issues, attitudes and trends shaping America and the world. It does so by conducting public opinion polling and social science research; by analyzing news coverage; and by holding forums and briefings. It does not take positions on policy issues.

The Center's work is carried out by seven projects:

• Pew Research Center for the People & the Press
• Pew Research Center's Project for Excellence in Journalism
• Pew Internet & American Life Project
• Pew Forum on Religion & Public Life
• Pew Hispanic Center
• Pew Global Attitudes Project
• Pew Social & Demographic Trends Project
