The Simple Online Data Archive for Population Studies is a Web accessible data archive of analysis-ready primary and secondary data files in the PRI Data Archive. Datasets are arranged in collections by dataset title.   Within each collection, users may view descriptive information often including links to abstracts and originating agencies or investigators; search the content of each collection for relevant variables; search across collections for variables; view accompanying electronic documentation; and finally, extract for download a personally tailored analysis-ready subset of a data collection in a format of their choosing -  SAS, Stata, or SPSS dataset and comma or tab delimited format.
