Percent, percentage, proportion, and rate
“The percentage” shows how a quantity is measured on a scale from 1 to 100
as in “a high/low percentage.” However, “percent” refers to a specific amount
on this scale as in “35%.” Similarly, “the proportion” gauges a quantity in a
general way that is not necessarily on a 1-100 scale as in “a large/small
proportion.” On the other hand, “the rate” calculates the frequency as in “the
crime rate.” In other words, percentage, proportion, and rate all describe
quantities as part of a total.
