FoodAPS-1 captured detailed household-level information about purchases and acquisitions of food items intended for consumption at home and away from home, as well as foods acquired through USDA food and nutrition assistance programs. The data also include information about factors that affect food purchase decisions, such as the number and characteristics of people in the household, their available resources (including food and nutrition assistance program benefits, if any), and the array of stores and restaurants that are nearby. The nationally representative sample of 4,826 households includes four distinct sub-groups, based on household income and participation in the Supplemental Nutrition Assistance Program (SNAP).

The approach for creating the PUFs included categorizing or top-coding variables with some risk of data disclosure and suppressing variables with a very high risk of disclosure. These actions were based on extensive initial disclosure risk analyses, which included the following steps: Identifying personal identifiers, geographic information, and contextual variables (variables that can indirectly identify a geographic area); Evaluating the existence of other publicly available files; Evaluating the disclosure risk associated with release of the sampling and variance estimation variables; Evaluating the disclosure risk associated with release of key variables (i.e., visible variables) through extensive frequency tables and various risk metrics; and Exhaustive review of each data item in the RUFs to determine whether any of the data presented a non-negligible risk of individual disclosure. A list of variables only available in the RUF can be found in Appendix A of the FoodAPS User Guide (https://www.ers.usda.gov/foodaps)

The Tenure, Ownership, and Transition of Agricultural Land (TOTAL) Survey is a comprehensive study of all land rented out for agricultural purposes, including both land rented out by those who are themselves farmers and ranchers (operator landlords) and land rented out by those who do not operate a farm themselves (non-operator landlords).

The Survey of Irrigation Organizations is intended to provide a nationally representative assessment of irrigation water-delivery entities and groundwater management districts serving the U.S. irrigated sector. The dataset will include information on organization structure, irrigation infrastructure and system management practices, and water use by source, with a special emphasis on institutional measures and conservation initiatives that enhance drought resilience and long-term water-supply management.

The Agricultural Resource Management Survey (ARMS) is the U.S. Department of Agriculture's primary source of information on the production practices, resource use, and economic well-being of America’s farms and ranches. The results of this survey give farmers, ranchers, and many others factual insights into many aspects of farming, ranching, and conditions in agricultural communities.

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.
