If you ever intent to study law, become involved in a situation dealing with disparate impact, or are at the receiving end of disparate impact, knowing the legal definition may be helpful too. The DoJ spells[1] out the legal definition of disparate impact as so:
ELEMENTS TO ESTABLISH ADVERSE DISPARATE IMPACT UNDER TITLE VI
Identify the specific policy or practice at issue; see Section C.3.a.
Establish adversity/harm; see Section C.3.b.
Establish disparity; see Section C.3.c.
Establish causation; see Section C.3.d.
