Profiling • Numbers disaggregated by sex, age and locations • Covers the whole target population through estimations and sampling techniques. • Wide range of socio-economic and needs related data • Provides a common baseline dataset • Scientific approach • Collective approach • Unit of measurement is individual or household

  4. Profiling Methodologies • Quantitative methods • 1- Rapid population estimation A- Aerial satellite imaging B- Flow monitoring C- Dwelling Count D- Head Count E- Counting using sampling methods • 2- Household survey • 3- Registration • 4- Population Census • Qualitative methods • 1- Focus Group discussion • 2- Semi-structured discussions • 3- Key informant interviews

  5. Samplingin the Humanitarian Context

  6. Probability sampling:Sampling that uses random selection to choose units to be examined or measured“random” does not mean haphazardHousehold surveys generally use some form of probability sampling
