Which of the following classes is protected from discrimination by federal fair housing laws?

National origin is indeed a class protected from discrimination by federal fair housing laws, specifically under the Fair Housing Act. This law prohibits discriminatory practices in housing based on a variety of characteristics, including race, color, religion, sex, familial status, disability, and national origin. This means that individuals cannot be denied housing opportunities or treated unfairly in housing-related activities due to their national origin, which encompasses where a person is from or their ethnic background.

In contrast, economic status, employment status, and age are not federally protected classes under the Fair Housing Act, even though certain states and local jurisdictions may have their own laws that offer such protections. Understanding these distinctions is important for ensuring compliance with fair housing regulations and promoting equality in housing opportunities.
