In determining whether a class is suspect, quasi-suspect, or nonsuspect, the Supreme Court has focused on a number of class attributes including:
(1) whether the group singled out has suffered from a history of discrimination;
(2) whether the trait generally bear no relationship to a person's ability to contribute to society;
(3) whether the trait is often singled out to reinforce prejudice against the group or label the group as inferior;
(4) whether the group is politically powerless by its numbers in the population, by under-representation in government, or by its inability to influence the legislative agenda; and
(5) whether the trait shared by the group is a distinct trait and one that is an immutable or unalterable characteristic or a trait central to personal identity.
