"ResearchDataGov.org is a central data portal of the federal statistical agencies and units, created in response to the Foundations of Evidence-based Policymaking Act of 2018. The site is the single portal for discovery of restricted data in the federal statistical system. The agencies have provided detailed descriptions of each data asset. Users can search for data by topic, agency, and keywords. Questions related to the data should be directed to the owning agency, using the contact information on the page that describes the data. In late 2022, users will be able to apply for access to these data using a single-application process built into ResearchDataGov. ResearchDataGov.org is built by and hosted at ICPSR at the University of Michigan, under contract and guidance from the National Center for Science and Engineering Statistics within the National Science Foundation. The data described in ResearchDataGov.org are owned by and accessed through the agencies and units of the federal statistical system. Data access is determined by the owning or distributing agency and is limited to specific physical or virtual data enclaves. Even though all data assets are listed in a single inventory, they are not necessarily available for use in the same location(s). Multiple data assets accessed in the same location may not be able to be used together due to disclosure risk and other requirements"--About Us page

The US National Archives and Records Administration (NARA) partnered with the Indigenous Digital Archive project of the Museum of Indian Arts and Culture in Santa Fe to provide context about and connection to the National Archives' holdings of the Ratified Indian Treaties. The IDA Treaties Explorer has conserved and digitized the Ratified Indian treaties in its holdings, 374 treaties between indigenous peoples and the United States (and its predecessor colonies). The IDA Treaties Explorer lets one also explore maps and see which tribes are associated with which treaties

"The National Neighborhood Data Archive (NaNDA) is a publicly available data archive containing contextual measures for locations across the United States. NaNDA offers theoretically derived, spatially referenced, nationwide measures of the physical and social environment. Each NaNDA dataset represents a set of measures on a single topic of interest. Examples of topics to be found in NaNDA (now or in the future) include socioeconomic disadvantage and affluence, walkability, crime, land use, recreational centers, libraries, fast food, climate, healthcare, housing, public transit, and more. Measures are available at multiple levels of spatial scale, from county to census tract to block group. New measures and spatial scales are added regularly. Anyone with research questions that address "place" - researchers, students, clinicians, policy makers, public health departments, and community organizations, among others - can download NaNDA contextual measures and link them with other data sources (such as survey data, cohort studies, electronic medical records, or other microdata). NaNDA is administered by the Social Environment and Health program at the University of Michigan Institute for Social Research. Funding for NaNDA comes from the National Institute on Aging and the National Institute on Disability, Independent Living, and Rehabilitation Research."

Google's search engine for datasets on the web. The majority of governments in the world publish their data and describe it with schema.org, which makes it easier for Google to index. Dataset Search has indexed almost 25 million of these datasets, giving you a single place to search for datasets and find links to where the data is. Users can filter the results based on the types of dataset (e.g., tables, images, text), or whether the dataset is available for free from the provider. If a dataset is about a geographic area, you can see the map

PatentsView is a patent data visualization and analysis platform intended to increase the value, utility, and transparency of US patent data. The initiative is supported by the Office of Chief Economist in the US Patent & Trademark Office (USPTO) PatentsView is intended to encourage the study and understanding of the intellectual property (IP) and innovation system; to serve as a fundamental function of the government in creating "public good" platforms in these data; and to eliminate redundant cleaning, converting and matching of these data by individual researchers, thus freeing up researcher time to do what they do best--study IP, innovation, and technological change. Access patent information via API, bulk download, or data query. The data are derived from USPTO bulk data files. These data are provided for research purposes and do not constitute the official USPTO record.
