Inquiring about an applicant's age and date of birth may be prohibited by which law?

The Age Discrimination in Employment Act (ADEA) specifically prohibits age discrimination against individuals who are 40 years of age or older. One of the implications of this law is that employers are restricted from inquiring about an applicant's age or date of birth, as such questions can potentially lead to discriminatory practices. The act aims to ensure that older employees are not unfairly treated in hiring, promotions, or job retention based on their age.

In contrast, while the Civil Service Act of 1970 and Title VII of the Civil Rights Act of 1964 address various forms of discrimination, they do not specifically focus on age-related inquiries in the same manner. Title VII addresses discrimination based on race, color, religion, sex, or national origin, and the Civil Service Act pertains to government employment practices. Therefore, the ADEA is the most relevant law regarding prohibitions on discussing an applicant's age or date of birth during the hiring process.
