The Committee on National Statistics is a group that "serves to contribute to a better understanding of important national issues by working to improve the statistical methods and information on which public policy decisions are based."
Housed at The National Academies as part of the U.S. Federal Government, CNSTAT quietly is doing a lot of interesting work. Here's a list of their current projects, and another list of completed projects.
Of particular interest to community indicators practitioners in the United States is this set of links to statistical agencies. It's a treasure trove of information (hey, how did Statistics Canada get in there?) If you haven't seen the list before, poke around -- I went to the U.S. Dept. of Health and Human Services' Data Council Gateway to Data and Statistics and almost immediately found data I needed for an upcoming race relations progress report.
Take a look, and let me know what you find useful.
