A/HRC/42/47/Add.3 71. Whilst acknowledging that constraints regarding data protection may prove challenging to the collection of disaggregated data regarding water and sanitation usage, the Special Rapporteur restates the vital nature of this enterprise. Only by collecting such data can the Government properly understand how socioeconomic and other characteristics affect the enjoyment of the human rights to water and sanitation by those in vulnerable situations, particularly in relation to how discrimination on the basis of these characteristics impacts this. Whilst current methods may be unreliable means of collecting data, due to unpredictable response rates, it is incumbent upon the Government to continue to collect this data and, where necessary, to invest greater resources to help maximise response rates, utilising, where appropriate, technology to assist this. The Special Rapporteur makes clear it is not necessary for the Government to collect information that identifies specific individuals, but rather to identify how access to water and sanitation differs depending on a personal characteristics, including, but not limited to, ethnicity, gender, age, wealth, migration status, religion, level of education, and whether they live in rural or urban areas. PROGRESS NOT STARTED: The Special Rapporteur is disappointed that progress has not started in collecting disaggregated data regarding water and sanitation. He reiterates his recommendation and looks forward to progress being made. 19
