Protected Categories Under Discrimination Laws

Federal law prohibits unfair treatment in the workplace, housing, education, and public services based on certain personal characteristics. Understanding which categories are legally protected is the first step in recognizing whether you may have experienced discrimination.

Race and color protections are among the oldest civil rights safeguards. Title VII of the Civil Rights Act of 1964 makes it illegal for employers with 15 or more employees to discriminate based on race or color. This applies to hiring, firing, pay, job assignments, promotions, layoffs, and training. The Fair Housing Act extends similar protections to rental housing, home sales, and mortgage lending. The Equal Credit Opportunity Act covers lending decisions. Color discrimination is distinct from race discrimination; it refers to discrimination based on skin tone rather than ethnic or national origin background.

Religious discrimination occurs when someone is treated unfairly because of their religious beliefs, practices, or lack of religion. Employers must provide reasonable accommodations for religious observance—such as schedule changes for prayer times, dietary needs, or religious holidays—unless doing so creates undue hardship. This applies to businesses with 15 or more employees and covers all aspects of employment including hiring, promotion, and termination.

Sex discrimination encompasses unfair treatment based on gender. Title VII prohibits sex-based discrimination in employment. The Fair Housing Act prohibits it in housing. Sex discrimination includes unequal pay for substantially similar work; sexual harassment; discrimination based on pregnancy, childbirth, or related conditions; and discrimination based on gender identity or sexual orientation (protected in many jurisdictions under sex discrimination laws). According to the U.S. Equal Employment Opportunity Commission, sex-based charges accounted for over 27% of all workplace discrimination complaints filed in fiscal year 2023.

National origin discrimination involves treating someone unfairly because of their country of origin, accent, ethnicity, or inability to speak English fluently. In the workplace, employers cannot refuse to hire or promote someone based on national origin, nor can they create a hostile work environment through ethnic slurs or stereotypes. In housing, it is illegal to refuse to rent or sell to someone based on national origin. This protection also covers discrimination based on citizenship status in certain contexts.

Age discrimination affects workers age 40 and older in workplaces with 20 or more employees. The Age Discrimination in Employment Act prohibits age-based decisions in hiring, firing, compensation, and job assignments. Common examples include "we need someone younger for this role," forcing early retirement, or laying off older workers while retaining younger ones in similar positions.

Disability discrimination protections cover physical and mental disabilities that substantially limit major life activities. The Americans with Disabilities Act requires employers, housing providers, and public accommodations to provide reasonable accommodations—modifications that allow people with disabilities to perform job functions, access housing, or use public services. Examples include wheelchair ramps, accessible parking, flexible schedules for medical treatment, or modified equipment. An estimated 61 million U.S. adults live with some form of disability, making this protection relevant to many workers and consumers.

Additional protected categories vary by jurisdiction. Some states and localities prohibit discrimination based on sexual orientation, gender identity, marital status, political affiliation, veteran status, or genetic information. The Genetic Information Nondiscrimination Act specifically prohibits employers and health insurers from discriminating based on genetic tests or family medical history. Understanding your local and state laws is important because they may offer protections beyond federal minimums.

Takeaway: Document the specific reason you believe you experienced discrimination. Was it based on a characteristic listed in federal law (race, color, religion, sex, national origin, age, disability) or a characteristic protected under your state or local laws? Identifying the protected category helps you understand which agency investigates your complaint and which laws apply to your situation.

Where to File Discrimination Complaints

Multiple agencies and organizations investigate discrimination complaints. Knowing where to file ensures your complaint reaches the correct authority with jurisdiction over your situation. Filing location depends on the type of discrimination and the context where it occurred.

The Equal Employment Opportunity Commission (EEOC) handles workplace discrimination complaints in the private sector and in state and local government agencies. The EEOC has offices in most major cities and accepts complaints in person, by mail, or online at eeoc.gov. For federal employees, the EEOC processes complaints through a different procedure. As of 2024, the EEOC received approximately 60,000 workplace discrimination charges annually. You do not need a lawyer to file with the EEOC, and filing with the EEOC is free.

The Department of Housing and Urban Development (HUD) investigates discrimination in housing, including rental properties, home sales, home loans, and homeowners insurance. HUD can be reached through its regional offices or through its online complaint portal. HUD also works with state and local fair housing agencies. In 2023, HUD's Office of Fair Housing and Equal Opportunity received over 4,500 housing discrimination complaints.

State civil rights agencies operate alongside federal agencies. Every state has a fair employment practice agency or civil rights division that investigates workplace discrimination. State agencies often have shorter processing times than the EEOC. In "dual-filing" states (those with agreements with the EEOC), filing a complaint with the state agency automatically files it with the EEOC as well. State housing discrimination agencies investigate housing complaints. You can locate your state's agency through your state government website or the National Association of Civil Rights Agencies.

Local human rights commissions exist in many cities and counties. These agencies investigate discrimination in employment, housing, public accommodations, education, and lending within their jurisdiction. Local commissions often offer services in multiple languages and may provide mediation services to resolve complaints without formal investigation. Some local commissions process complaints faster than state or federal agencies.

For education-based discrimination, Title IX complaints go to the Department of Education's Office for Civil Rights. This office investigates discrimination based on sex, including sexual harassment and assault in K-12 schools and colleges. For K-12 students, complaints can also go to your state's Department of Education. Title VI complaints (race, color, national origin discrimination in any federally funded program) go to the Office for Civil Rights as well. The office has regional offices that serve different geographic areas.

Public accommodations discrimination—being denied service at a restaurant, store, hotel, or entertainment venue—falls under Title II of the Civil Rights Act. You can file complaints with the Department of Justice Civil Rights Division, your state attorney general, or local law enforcement in some cases. Civil rights organizations also track public accommodations complaints.

Lending and credit discrimination is handled by several agencies depending on the type of lender. Complaints about banks go to the Consumer Financial Protection Bureau (CFPB) or the appropriate banking regulator. Mortgage lenders are regulated by HUD. The Federal Trade Commission handles complaints about other lenders. State attorneys general also investigate lending discrimination.

Some discrimination may involve overlapping jurisdiction. For example, employment discrimination based on disability goes to the EEOC, but if the employer is a housing provider engaging in housing discrimination, HUD also has jurisdiction. Many agencies allow you to file complaints without a lawyer, and agency investigation is free to the complainant.

Takeaway: Identify the type and location of the discrimination. If it occurred at work, contact the EEOC or your state fair employment agency. If it occurred in housing, contact HUD or your state/local housing discrimination agency. If it occurred in education, contact the Department of Education's Office for Civil Rights. Keep records of the agency names, addresses, and phone numbers relevant to your situation for reference during the complaint process.

The Complaint Process and Investigation Timeline

Understanding what happens after you file a complaint helps you know what to expect and how long the process typically takes. While timelines and procedures vary by agency, the basic framework is similar across most discrimination complaint systems.

The initial filing stage involves submitting a written complaint to the appropriate agency. Most agencies now allow online filing, which can be faster than mailing paper forms. When you file, you provide information about yourself, the respondent (the person or organization you're complaining about), the date(s) of the alleged discrimination, and a description of what happened. The agency assigns your complaint a case number and sends you a confirmation. This stage typically occurs within days of filing.

After filing, the agency conducts a "intake review" to determine whether the complaint falls within its jurisdiction and states facts that could constitute discrimination. If the complaint lacks required information, the agency may request clarification. Intake review usually takes one to four weeks. If the
