What does disaggregate mean?
Disaggregate means to separate a whole into its constituent parts, and it is especially common in technical, statistical, and policy writing. A researcher might disaggregate combined figures into categories such as age groups or regions; an administrator might separate a large organization into smaller operational units; and a material may break into separate substances. The verb can also be used without an object, describing the separation of a group into distinct elements. Its formal register distinguishes it from the broader word “separate,” while “desegregate” has the more specific social meaning of ending racial or institutional separation. In data analysis, disaggregating figures reveals patterns hidden by totals; in administration or politics, it can emphasize how a larger body comprises smaller groups. The word’s precision makes it useful whenever the relationship between whole and part is central to the analysis.

Where does disaggregate come from?
Disaggregate was formed in English by combining the prefix dis-, indicating reversal or separation, with aggregate. Aggregate comes from Latin aggregare, meaning “to assemble,” formed from ad-, meaning “to,” and gregare, meaning “to assemble,” which is related to grex, the Latin word for “flock.” The shared Latin ancestry also links the word to derivatives such as aggregation, aggregator, and gregarious.

How disaggregate is actually used
