In addition to this recommended minimum disaggregation, further disaggregation would in many areas be of policy relevance. For example, the child population could be disaggregated into smaller age groups as there are often significant differences in poverty rates between these age groups. Different rationale can be applied to this, for example related to policy objectives (for example pre-school, school age, secondary school), or age groups (0-4, 5-9, 10-14, and 15-17).
