INVESTOPEDIA EXPLAINS 'Quintiles'

Quintiles are often used to create cut-off points for a given population. For example, a government sponsored socio-economic study may use quintiles to determine the maximum wealth a family could possess in order to belong to the lowest quintile of society. This cut-off point can then be used as a prerequisite for a family to receive a special government subsidy aimed to help society's less fortunate.
