RDC Frequently Asked Questions
Question: How long does it take to review and approve a proposal?
Answer: The estimated time to review a proposal is 8 to 12 weeks. Researchers are encouraged to revise their proposal immediately upon receipt of comments in order for the proposal review process to continue as scheduled.
Question: If I make a change to my proposal, do I need to submit a new proposal?
Answer: This depends on the type of change. Minor changes, or amendments, will require you to update the proposal and may require an expedited review. Major changes, such as change in scope, will require you to submit a new proposal. New proposals must go through the full review process. Your RDC Analyst will be able to identify which course of action is best. Note, RDC management fees may be applied for all changes.
Question: After my proposal has been approved, what do I do next?
Answer: Complete all required confidentiality paperwork, prepare the dataset with the public use variables you have selected, and submit payment. Once you’ve met all access requirements, you may schedule your visit to the RDC.

Question: Can I merge my dataset in the RDC?
Answer: No. Your RDC Analyst will merge the public use or external data provided by you to the restricted variables requested in your approved proposal. This allows us to maintain security and assure that your dataset is ready for you when you visit.
Question: Can I bring statistical programming code with me?
Answer: No. You must email your code to your RDC Analyst at least five business days before your visit. All files, programs, reference materials, notes, must be reviewed before entering or leaving the RDC facility. Flash drives are not permitted. RDC Analyst cannot connect external drives to any computers. We encourage researchers to send the RDC Analyst electronic copies of resource documents (e.g., programming manuals, survey questionnaires, and/or data dictionaries) you may need onsite at least two days before your visit.
Question: How do I get my output?
Answer: You will save the output, along with a description of the output (this can be a title: a regression of…), and a description of any (sub)sample used in the output (e.g., black males age 20-29) to your project folder. Notify your RDC Analyst that your output is ready for review. Your RDC Analyst will review it to ensure there are no disclosures. If your output matches the output described in your approved proposal and there are no disclosure concerns, your RDC Analyst will email the output to you within three weeks.
Question: What if my output does not match the output described in my approved proposal?
Answer: You must amend your existing proposal or submit a new proposal. The RDC will not review output that does not match the output described in an approved proposal. Note, an approved proposal does not guarantee the release of output. Discuss your options with your RDC Analyst.
Question: How long will it take for me to receive my output?
Answer: Output review takes up to three weeks. Review time depends on the volume and complexity of the output and staff workload. We do our best to return output to you in a timely manner, so please plan to allow for the review time as stated here.
Question: Can I request special analysis software to use onsite?
Answer: Please see the list of software available at the NCHS RDCs. We do not provide technical assistance for any software packages. The researcher is responsible for all programming. Federal Statistical RDC users should contact the FSRDC to inquire about available software.
