Breaking Down the Meaning of Quintile

Many people have a deep interest in statistics about themselves, whether the information provided is about 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.
