A noticeable and usually unfair difference or inequality between two or more things.

Implies an unexpected, problematic, or unjust difference in level, amount, or treatment rather than a mere distinction.

The story behind the word. From Late Latin 'disparitas', combining the negative prefix 'dis-' with 'par' meaning equal. It originally entered Early Modern English to describe unequal conditions in trade and status.

Word relationships

inequality: Inequality is broader and can refer to mathematical or general imbalance, whereas disparity emphasizes an unwarranted gap.
divergence: Divergence refers to paths moving apart over time, whereas disparity describes a static state of difference.

parity: Parity denotes exact equality or equivalence in status, value, or pay.
uniformity: Uniformity emphasizes complete sameness in state or character across all units.

Commonly confused with

disparity vs variance: Variance is a statistical measure of spread within a single group, while disparity compares gaps between distinct groups.

Word family

disparate (adjective): Essentially different in kind; not allowing comparison.

Collocations

Example sentences

"The growing wage disparity between executive leadership and frontline staff sparked widespread debate." Economic policy analysis
"Public health researchers highlighted the stark regional disparity in access to emergency medical services." Healthcare distribution

Memory hook

Think 'DIS-PARITY' = DIS-able PARITY (destroying equality). Disparity is parity torn apart.

When not to use

Do not use for simple non-evaluative differences between neutral items, like shapes or colors.

Fun facts

The root 'par' also gives us 'golf par' (the standard standard of equality) and 'peer' (an equal).
