Life expectancy increased significantly in the 1900s, and many new pieces of legislation for equal opportunity within the American workforce are passed. Attempts to include age as a factor by which employers cannot discriminate in law begins with the Employment Opportunity Act of 1962 and the Civil Rights Act of 1964. The lack of data on age discrimination prompts Secretary of Labor Wirtz to commission the report "The Older American Worker: Age Discrimination in Employment.' Soon after its publication, in December 1967, the Age Discrimination in Employment Act is signed into law by President Johnson.
