From the U.S. Census:
We are pleased to announce the release of an updated Beta version of DataFerrett, which includes several new features designed to improve access to the 2005-2009 5-year ACS Summary File in DataFerrett.
DataFerrett is a unique data analysis and extraction tool-with recoding capabilities-to customize federal, state, and local data to suit your requirements. (FERRETT stands for Federated Electronic Research, Review, Extraction, and Tabulation Tool.) Using DataFerrett, you can develop an unlimited array of customized spreadsheets that are as versatile and complex as your usage demands.
The Census Bureau would greatly appreciate any feedback from the public regarding these new features.
