The U.S. government has long been an active gatherer and disseminator of information. In recent years, with the roll out of the data.gov website, it has made strides to make this data more accessible and useable by the public, researchers, app developers, and businesses. The site serves as a gateway to publicly available datasets from not only the federal government, but also state and local governments as well as universities. These data cover a wide range of subject matter including: education, employment, agriculture, and public safety. According to the site, the number of datasets available currently stands at over 192,000. The site also provides examples of businesses and organizations that rely on the data to power their sites/applications.
As some reviewers have pointed out, data.gov is not without its limits. For example, the currency of the data provided varies; in some cases, more recent data can be found on an agency’s own website. In addition, the file formats provided vary quite a bit, from HTML to XML, CSV, and others. The scope and depth of participation by federal agencies with the data.gov initiative vary as well; details can be found here.
To search the available datasets from the main page, enter a keyword(s) in the main search box. Or, to browse available datasets, select a topic from the “Browse Topics” icons. Then select the “Data” or “Data Catalog” tab to view the available datasets. These sets can then be narrowed using the filters on the left side of the screen. Results can be filtered based on the file format, the agency supplying the data, and other attributes.
