Definition & calculation
Numerator: Number of assessed sites meeting the agreed minimum usable surface area per person and the safe site-planning layout criteria
Denominator: Total number of assessed displacement sites
Site area, population and layout are measured and compared against the agreed planning standard (e.g. minimum usable m² per person, firebreaks, drainage); compliant sites are divided by all assessed sites.
Formula: (Numerator ÷ Denominator) × 100
Means of verification
Site profiling; GIS/site mapping; camp management technical assessment
Interpretation
Direction: Higher is better
Typical reporting frequency: Monthly or quarterly
Guidance & common pitfalls
Overcrowding drives protection and public-health risk; measure usable area (excluding unusable terrain) rather than gross site area, and note that compliance is influenced by population movement beyond the intervention's control.
