The carroyed data (200 m tiles) comes from the source Tax Revenues Localised 2010. They are useful for obtaining information at sub-communal levels according to user-specific splits. The dissemination of these data must therefore comply with the rule of at least 11 households per geographical unit of observation.
The method used to comply with this rule is to group tiles that are too low in size, into larger rectangles. Only the total population is not subject to this rule and can therefore be disseminated on all tiles.
In addition, variables considered sensitive, in particular household tax income, are treated to ensure confidentiality.
