The IQ for mental retardation was a score of below 85. They updated it in 1973 because most blacks were being sent to special education because their mental capabilities were that of a retarded person.
It’s not just blacks: the average IQ in India is 76 - almost 10 whole points BELOW RETARDATION.

The AAMD (now AAIDD) revised its 1973 manual: IQ cutoff dropped from ~85 (1 SD below mean, + "borderline" category labeling ~15-16% of population) back to ~70 (2 SD, ~2%). Official rationale: reduce overdiagnosis/stigmatization of mildly low scorers who weren't functionally impaired; emphasize adaptive behavior deficits alongside IQ. Secondary sources note it responded to civil rights concerns over disproportionate labeling of minority students (mainly Black Americans, whose group mean IQ is ~85) in special ed. This sharply cut eligibility for services.
