The materials in this section were compiled for the publication of Hispanic Americans in Congress, 1822–2012. These charts were developed to answer reference questions often posed by Member offices, researchers, and the general public. We have also included historic political songs that served as illustrations in the print publication. Forty-six of the 127 Hispanics who have served in Congress are current Members—42 in the House and four in the Senate. In total, there have been 121 Hispanic Members of the House of Representatives and nine Senators. Three have served in both chambers.
