Amending America: Proposed Amendments to the United States Constitution, 1787 to 2014

This dataset provides information about more than 11,000 proposed Constitutional amendments introduced in the United States Congress from 1787 to 2014. This dataset is a compilation of information from several Congressional publications as well as a search for Constitutional amendments on the Congress.gov website.

Data available for each proposed amendment varies by source publication. Each entry may include a source of information, title or description of amendment, date of introduction, Congress, Congressional session, joint resolution number, sponsor name, sponsor state or territory, and the committee of referral.

The National Archives and Records Administration created this dataset as part of the Amending America initiative. To prepare for the 2016 "Amending America" exhibition at the National Archives Museum in Washington, D.C., NARA volunteers and staff transcribed and edited over 11,000 entries representing proposed amendments to the U.S. Constitution, as recorded by Congress.
