UNSD Water Questionnaire

UNSD Water Questionnaire

• Supply and Use

2
Questionnaire Design

• Keep it simple
• Keep the number of questions to a useful minimum
• Ask for the most useful information
• Ask for information for which we will get a
  response
• Use intuitive layout
• Water cycle
• Renewable Fresh Water resources
• Water abstraction by source
• Water Use by Supply Category and Activities
• Waste Water Treatment

2006 Water Questionnaire

• Layout
• Intuitive and easy to
• Minimize misunderstandings and ambiguity
• Content
• Harmonize concepts and definitions to
  international norms
• Focus on most important information for which we
  will get a reasonable response rate
