Disparate impact

In United States anti-discrimination law, the theory of disparate impact holds that practices in employment, housing, or other areas may be considered discriminatory and illegal if they have a disproportionate "adverse impact" on persons in a protected class. Although the protected classes vary by statute, most federal civil rights laws protect based on race, color, religion, national origin, and gender as protected traits, and some laws include disability status and other traits as well.
