Methodology and Sample

The districts covered in the PVA were selected purposefully based on the following criteria:
  • Prior environmental hazards such as floods, flash floods, or droughts
  • Representativeness in terms of ecological, ethnic, livelihoods, and socioeconomic factors
Selection of households involved a two-stage process. In the first stage, districts were stratified based on socioeconomic and ecological factors and a predetermined number of settlements was selected randomly from each strata.
In the second stage, households were selected randomly from each selected settlement. Household selection followed a random route procedure.
A sample size of about 385 households was used at the district level to ensure representative data on poverty and vulnerability. In each district, the number of households surveyed in a settlement was proportional to the total population. Results are representative at the district level and not at the sub-basin, state/province or national level.
