Knowledge of sampling and experience in conducting surveys is very important. You must ask for external help from a skilled social scientist.

Steps required to prepare for the survey

• Sampling design: Decide on the sample size and the sampling method.
• Fieldwork procedures:  Decide upon the staffing requirements and the organization of field units to apply the sampling design in the selected time frame.
• Finalizing questionnaire: Pilot, revise, and (if needed) translate questionnaire.
