A georgaphical base for statistics Small as possible Comparable in terms of size or population Complete coverage across the EU Linked to a system of statistical data determined by user needs The Tandem Consortium
Assumptions Use existing systems of statistics on both regular and irregular tessellations The NSI’s will be reluctant to let micro data outside their borders therefore contain also methods to aggregate data for different purposes System must be built respecting existing international modelling standards to fit other data-sets The Tandem Consortium
Focus From: Small Statistical areas To: Small area statistics To study the feasibility of a system of small statistical areas for EU To: Small area statistics To study the feasibility for a system of small area statistics for the EU The Tandem Consortium
