UNSD Water Questionnaire

Supply and Use

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
