Data is collected through a representative population-based household survey, with direct observation.
Two measurements are required for this indicator:
1. Presence of an "improved" latrine which meets JMP definitions and
2.. Evidence (through observation) that the latrine is in use
Calculation: The percent is derived by dividing the number of households using an improved latrine by the total number of households surveyed in the target population.
Numerator: Number of households with an observed latrine meeting "improved" definition and in use
Denominator: Number of households surveyed in the target population
Questionnaire to determine utilisation or direct observation of either usage of latrines or a reduction in open defecation
