ICPSR welcomes and encourages deposits of digital data. Depositing data into ICPSR is free. Deposits are made using a secure data deposit form to describe the data collection and upload content. You do have to have an active MyData account with ICPSR in order to deposit data (please see Creating an ICPSR Account for more information).
Why deposit data with ICPSR? ICPSR offers:
Free Data Deposits. There is no cost to deposit data into ICPSR.
Data Curation. ICPSR enhances and adds value to data by making them easier to use. ICPSR staff also describe data full for discovery and also protect respondent privacy.
Long-Term Preservation. ICPSR ensures long-term data availability.
Worldwide Access to Datasets. ICSPR offers data in the major statistical package formats and also offers online analysis for many datasets. Usage statistics for your deposited datasets are available on request.
User Support. ICPSR staff are available to answer questions about downloading and using data.
Levels of Access. ICPSR offers restricted data services and secure data enclaves.
Aggregation of Publications. ICPSR will create a database of citations based on analyses of your data. This database is harvested by social science indexes, such as Web of Science, which also provides credit to the original investigator.
Data used for secondary analysis is published more widely than data not shared. Sharing data extends the research productivity of the primary investigator. Archiving data also helps researchers meet grant and journal requirements to deposit their datasets.
Deposits should include all data and documentation necessary to independently read and interpret the data collection. ICSPR's Guide to Social Science Data Preparing and Archiving contains a discussion of best practices for preparing data for deposit and sharing.
1. Data File. ICPSR encourages depositors to submit data files as SAS, SPSS, or Stata files. ASCII files are also acceptable if they are accompanied with setup files. Datasets in other formats are accepted as well.
Each variable in the data collection should have a set of exhaustive, mutually-exclusive codes. Variable labels and value labels should clearly describe the information or question recorded in that variable. Missing variables should also be defined.
ICPSR will accept data with identifying information under conditions consistent with the consent of the study participants and the approval of West Texas A&M University's Institutional Review Board (IRB).
2. Documentation. Documentation files are vital to interpreting a data collection and should thoroughly explain the data collection. Examples of documentation include codebooks, data collection instruments, summary statistics, project summaries and bibliographies of publications relating to the data. Documentation may be submitted as Microsoft Word, ASCII, and DDI XML files, among other formats. Documentation with the question text integrated with the variable information is preferred.
3. Description. Every new or revised ICPSR study includes a study description, which provides summary information about the data collection. Study descriptions are invaluable resources to data users, and include both general information, such as the study title and summary, as well as more detailed information about the study design and methodology. Much of the information that ICSPR data archivists use to create the study description comes from the ICPSR data deposit form.
