What Happens to My Data After the Deposit?

After a data collection is deposited at ICPSR, a data archivist reviews the documentation and data, builds a study description, enhances and quality-checks the data, approves the data collection for distribution on the ICPSR website, and archives the data for long-term preservation.

Access and Preservation Formats

ICPSR makes quantitative data files available in several widely used formats, including ASCII, tab-delimited (for use with Excel), SAS, SPSS, and Stata. Documentation is provided as PDF.

For long-term preservation, data are stored in accordance with prevailing standards and practice. Currently, ICPSR stores quantitative data as ASCII along with setup files for the statistical software packages, and documentation is preserved using XML and PDF/A.
