The process or result of disaggregating; the breakdown of a combined whole into separate components or parts.
From disaggregate + -ation. Became a standard term in data science, statistics, and policy analysis particularly from the 1990s onward.
Disaggregation is how researchers discovered that 'racial gaps in wealth' or 'gender gaps in STEM' were actually hiding even bigger disparities when you break down the data by generation, region, or education level.
