Americans love statistics about themselves, whether they inform us about our income, ice-cream consumption, or trash production. And any such rating can be divided into fifths, or quintiles. The fifth or lowest quintile would include the 20 percent of the population who make the least money or eat the least ice cream or generate the least trash, and the first quintile would include the 20 percent who make, eat, or generate the most.

Origin and Etymology of quintile

Latin quintus + English 2-ile
