5. 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

6. 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

7. Focus From: Small Statistical areas To: Small area statistics
To study the feasibility of a system of small statistical areas for EU
To:
