The new paper, published in the American Review of Political Economy, says almost 7,600 men, women and children as young as 10 were surgically sterilised under the programme, preventing people deemed "feebleminded" and others from becoming parents.
They were sterilised as part of a Eugenics Protection Law that was in effect from 1948 to 1996. Some of the victims were physically or cognitively disabled, according to the board that approved their sterilisation. Others had behavioural issues.
