What does disaggregate mean?
To disaggregate is to take something that has been gathered together and separate it into its component parts. The word belongs chiefly to the vocabulary of statistics, economics, and research: analysts disaggregate national figures into regional ones, or overall averages into breakdowns by age, gender, income, or other categories, precisely because patterns hidden in the aggregate often emerge once the data is split apart. It carries a neutral, technical tone and appears almost exclusively in formal writing — reports, papers, dashboards — where precision matters. Its opposite is aggregate, and it should not be confused with desegregate, which refers specifically to ending social separation such as racial segregation. Derived from Latin roots meaning to part from the flock, disaggregate is a useful word whenever a single lump of information needs to be examined piece by piece.
verbTo separate something that has been combined or aggregated into its individual component parts, especially in statistical or technical analysis.
- To separate aggregated material, data, or information into its constituent components for analysis.
"The report disaggregates the national data by age, income, and region."
"Economists disaggregate inflation figures to see which sectors are driving price increases."
"The survey results were disaggregated so that responses from rural and urban respondents could be compared."
Every time a statistician 'breaks down' data, they're quietly doing the opposite of what a crowd does: un-gathering the flock.

Etymology of disaggregate
Disaggregate derives from the Latin verb disgregare, formed from dis- ('apart') and grex, gregis ('flock, herd') — literally 'to part the flock'. It entered English via post-classical Latin in the early modern period, alongside its sibling words aggregate ('gather into a flock') and segregate ('set apart from the flock'). The same root gives us gregarious ('sociable, flock-loving') and congregation ('a gathering').
