Country files from the UNSD/UNEP data collection on environment statistics
In 2018 UNSD launched a round of data collection for environment statistics through the UNSD/United Nations Environment Programme Questionnaire 2018 on Environment Statistics. This website contains the country replies to the water and waste sections of the UNSD/United Nations Environment Programme Questionnaire 2018.
As part of the data validation process, UNSD sent questions to several countries for clarification. When countries replied with corrections, the original country files were modified. If a country did not reply to UNSD questions, UNSD removed from the files the figures or footnotes which are likely to be incorrect. The country files are updated as new data are received from the countries.
The main aim of the website is to share country data and to avoid multiple collections of the same data. International organizations that intend to collect these or similar data from countries are requested to coordinate with UNSD before launching their data collection activity.
