% of monitored displacement sites with no outstanding critical (life-threatening) service gap at the end of the reporting period

Numerator: Number of monitored displacement sites with zero unresolved critical (life-threatening) service gaps recorded at reporting period end

Denominator: Total number of displacement sites monitored during the reporting period

Using site monitoring and service-mapping data, classify each site by whether any critical service gap remains open at period end; divide sites with none by all monitored sites and multiply by 100.

Formula: (Numerator ÷ Denominator) × 100

Site monitoring reports and service-mapping / gap-tracking database

Typical reporting frequency: Baseline, midline and endline (or annual)

Critical gaps are those threatening life or basic survival (e.g. no safe water, no access to health care, no functioning latrines); agree the threshold with the coordination group. This captures the end-state coverage condition, distinct from indicators measuring referral or resolution speed.
