What is DataFerrett?
DataFerrett allows users to analyze available datasets without the need for specialized statistical software such as SAS, SPSS or STATA. The American Community Survey is one of the datasets available for analysis using DataFerrett. The user is able to select variables of interest and recode as needed. Results can be saved for further use. PUMS microdata can be downloaded in pre-formatted or delimited files for analysis using DataFerrett. An excellent description is available from the Census publication A compass for understanding and using American Community Survey data: What PUMS data users need to know.
