The Survey of Doctorate Recipients (SDR) provides demographic, education, and career history information from individuals with a U.S. research doctoral degree in a science, engineering, or health (SEH) field. The SDR is sponsored by the National Center for Science and Engineering Statistics and by the National Institutes of Health. Conducted since 1993, the SDR is a unique source of information about the educational and occupational achievements and career movement of U.S.-trained doctoral scientists and engineers in the United States and abroad.

Survey of Doctorate Recipients (FSRDC Version)

Includes educational institution identifiers for degrees earned and state-level identifiers for residency and employer location, which are not available on the PUF. Values of salary and income are rounded and top-coded on the PUF.

The Longitudinal Business Database (LBD) is a research dataset constructed at the Census Bureau using a variety of survey and administrative data sources.  Currently, the LBD contains the universe of all U.S. business establishments with paid employees beginning in 1976. The LBD contains basic information on establishment size, industry, location and ownership that permit researchers to analyze establishment demographics. The LBD is updated annually.  

The LBD offers researchers a number of features not available in other longitudinal datasets.  These include:

Long Time Series  - The LBD contains complete establishment histories from 1975.  Precise birth and death year information are available for most establishments.

Industrial Scope - The LBD contains all employer establishments that are in scope for the Economic Census (i.e., all manufacturing, mining, construction, retail, wholesale, service, TCU and FIRE establishments) as well as a large number of public administration and other out of scope entities.

Improved Longitudinal linkages - In constructing the LBD, great care was taken to provide researchers with the most complete and accurate set of longitudinal establishment linkages possible.  This substantially reduces the number spurious establishment births and deaths observed in the data.  In addition, the LBD provides researchers with detailed flags that describe, for each establishment, the nature of the linkages over each year an establishment is observed in the data.

Linkages to other micro data - The research capabilities of the LBD can be greatly and easily enhanced by linking it to other establishment and firm information via the Employer Identification Number (EIN).

The Administrative Data Research Facility (ADRF) is a secure cloud-based computing platform designed to promote collaboration, facilitate documentation, and provide information about data use to the agencies that own the data. The ADRF has provided secure access to over 100 confidential government datasets from 50 different agencies at all levels of government. More information on ADRF is available at https://coleridgeinitiative.org/adrf/.

Remote access to restricted-use data at the authorized licensed location via the the Administrative Data Research Facility (ADRF) by a connected, networked computer.  

Researchers may access restricted-use National Center for Health Statistics (NCHS) data at Research Data Centers (RDCs) located in Hyattsville, MD, Atlanta, GA, Rockville, MD, and Washington DC (government employees only). The NCHS RDCs are open by appointment only during regular business hours. The NCHS RDC computers are not connected to the Internet, and they have standard statistical software. An RDC Analyst will review all materials brought into the RDC and will review any notes, code, or output the researcher may want to take out of the RDC. Electronic devices (e.g., cell phones and laptops) are not permitted in the RDC. Some NCHS projects are authorized to access NCHS data at Federal Statistical RDCs (FSRDC). Non-US Citizens: In general, non-US citizens are not granted access to NCHS RDCs and are encouraged to use Federal Statistical RDCs to access restricted-use NCHS data.

Access via physical data enclaves in Atlanta, GA; Hyattsville, MD; Rockville, MD; or Washington, DC (government employees only).

NCSES Secure Data Access Facility (SDAF) houses NCSES restricted-use data and provides secure remote access to researchers. After researchers have submitted a restricted-use data application, received approval from NCSES, and have been trained on how to use the SDAF, they can login using an approved computer and a private internet connection. Each researcher has access to their own, personal file space and to a suite of software that can be used to store, access, and analyze data. For more information on accessing NCSES restricted-use data, please visit https://ncses.nsf.gov/about/licensing. 

The NCSES Secure Data Access Facility is a virtual data enclave where approved researchers access NCSES restricted-use data.

USDA offers offsite remote access via a secure internet connection using the researcher’s own computer and web browser to approved datasets for data analysis within the Data Enclave. Each researcher has access to their own personal file space and to a suite of software that can be used to store, access, and analyze data.

Data can be used by the researcher(s) at their institutions via a method and following requirements set by the agency owning the data. These might include a non-networked computer, a secure office, or other provisions deemed necessary to ensure security.

Data can be used at the user`s institution following the license agreement.

Researchers share four secure workstations at BEA’s headquarters at the Suitland Federal Center in Suitland, MD. Workstation use is by appointment only. Due to pandemic-related restrictions that currently prevent access at the physical data enclave, BEA is temporarily providing access at the user`s domicile. A security clearance is required to access the BEA network.

BLS Onsite access is available in a researcher room at the BLS national office in Washington, DC.  Researchers with approved projects can reserve time during normal business hours to use BLS workstations connected to an internal server where all data and project files are stored.  More information is available at www.bls.gov/rda/onsite-at-bls.htm.

Federal Statistical Research Data Centers (FSRDCs) are Census Bureau facilities, housed in partner institutions, that meet all physical and information security requirements for access to restricted–use micro data of the agencies whose data are accessed there. Remote access via secure Virtual Desktop Interface (VDI) is permitted for researchers working with selected data, at the discretion of the data-owning agency. All FSRDC researchers must obtain the Census Bureau`s Special Sworn Status and successfully complete a thorough background investigation prior to accessing an RDC.
