[1] Anti-discrimination laws vary by jurisdiction with regard to the types of discrimination that are prohibited, and also the groups that are protected by that legislation.
[2][3] Commonly, these types of legislation are designed to prevent discrimination in employment, housing, education, and other areas of social life, such as public accommodations.
Anti-discrimination law may include protections for groups based on sex, age, race, ethnicity, nationality, disability, mental illness or ability, sexual orientation, gender, gender identity/expression, sex characteristics, religion, creed, or individual political opinions.
Anti-discrimination laws are rooted in principles of equality, specifically, that individuals should not be treated differently due to the characteristics outlined above.
[6] Courts may take into account both discriminatory intent and disparate impact in determining whether a particular action or policy constitutes discrimination.
[18] This law prohibits any use of direct or indirect discrimination on the basis of age, sexual preference, marital status, birth, wealth, religion or belief, political or syndical opinion, language, current or future state of health, disability, physical or genetical property or social origin.
The Equality Act contains provisions forbidding direct, indirect, perceptive and associative discrimination on the basis of sex, race, ethnicity, religion and belief, age, disability, sexual orientation and gender reassignment.
[23] In 1868 after the American Civil War, the Fourteenth Amendment to the United States Constitution was ratified, including the Equal Protection Clause.
Nevertheless, the promises of this and other Reconstruction Amendments went largely unfulfilled for nearly a century thanks to the profusion of racist Jim Crow laws designed to oppress persons of color and reinforce racial segregation in the United States.
[33] However, there is evidence to suggest that the decrease in employment rates is partially explained by increased participation in educational opportunities.
In many nations with anti-discrimination legislation, women are excluded from holding certain positions in the military, such as serving in a frontline combat capacity or aboard submarines.
