Disaggregate

To separate a whole into its component parts; to break down aggregated data by category.

From Latin 'aggregare' (to add to a flock), preceded by 'dis-' (apart). Statistical and analytical usage prominent since the mid-20th century.

"The revised IIP series with 2022-23 base year will disaggregate manufacturing output more finely, capturing electronics, EV powertrains, and rare-earth processing as distinct sub-categories."
