A paper elaborating the methodology used by MICS Programme for anonymising cluster geocodes is underway, but until then, more information about the methodology can be found in a previous news piece.
The MICS Geocode Plugin “MICS Geocode Plugin (version 1.1)” is published together with manuals on how to install and how to use. These can be found on the Tools pages (Survey design, under Sampling and Mapping tools).
As with all MICS tools, this plugin and manuals carry MICS branding and terminology but can be used for any household survey.
