Congress passes the Open Government Data Act, which requires public information to be open to the public by default in a machine readable format
On December 21, 2018, the United States House of Representatives voted to enact H.R. 4174, the Foundations for Evidence-Based Policymaking Act of 2017 …
Context & Ripple Effects
The House vote on H.R. 4174 caps a multi-year push to codify open data rather than leave it to agency discretion: two years earlier, MIT Media Lab's Data USA visualization of public government data showed demand for structured federal data outpacing what agencies were obligated to publish, and the White House's draft open source software policy had already moved toward treating government-produced code and information as shareable assets.
First-order effects
- Federal agencies must now default to publishing public information in machine-readable form, converting what was voluntary practice into statutory obligation under the Foundations for Evidence-Based Policymaking Act.
Second-order effects
- Tooling built on scraped or piecemeal federal data — like Data USA's visualization work — gains a reliable, standardized feed, shifting value from data acquisition to analysis and presentation layers.
Third-order effects
- If the default-to-open mandate holds after signing — as the related coverage shows it did when Trump signed the OPEN Government Data Act in January 2019 — government data becomes infrastructure for third-party products, and the policy debate shifts from access to quality and maintenance, alongside adjacent transparency measures like the Cyber Vulnerability Disclosure Reporting Act's reporting requirements for DHS.
The trend: US government information policy is moving from discretionary release to open-by-default statute, with Congress converting ad hoc transparency projects into standing legal obligations.
