百分点

A percentage point is a unit of measurement used to express the difference between two percentages. Unlike a percentage, which is a proportion of a whole, a percentage point directly measures the absolute difference between two percentages.

The character 百 (bǎi) means 'hundred,' 分 (fēn) means 'part' or 'fraction,' and 点 (diǎn) means 'point.' Together, they literally translate to 'hundred part point,' reflecting the concept of a single unit in a percentage scale.

Percentage points are commonly used in economics, statistics, and finance to describe changes in rates, such as interest rates or inflation rates. For example, if an interest rate rises from 5% to 6%, it has increased by one percentage point, not 1%.
