Definition

Aggregation and disaggregation are reporting judgements about combining information that shares relevant characteristics and separating information when combination would obscure material differences, concentrations, locations or affected groups.

Overview

What it means in practice

A global total can be useful, but it can also hide a severe impact at one site or within one worker group. The reporting level should follow the decision and the pattern of impact, not only the convenience of the data system.

Why it matters

Good disaggregation makes concentrations, inequalities and local effects visible. Good aggregation keeps reports usable without erasing information that could change a user's judgement.

Review question

Would a reasonable user reach a different conclusion if the information were separated by geography, site, activity, value-chain stage or affected population?

Review

Public comments appear only after editor acceptance. Draft comments stay in the review queue.
