The Task
• From the Commission’s – Quest to improve the comparability of statistics across the EU
• To the Tandem Consortium’s– Design for a system of small area statistics– Based on a system of small statistical areas– To liberate statistics from administrative areas

3 Questions
• Why: A question of meeting ”User needs”• What: A question of Products and Services• How: A question of a Method for Development
![Page 4: Tandem l&ll](https://reader036.vdocuments.site/reader036/viewer/2022062222/56815d11550346895dcb1143/html5/thumbnails/4.jpg)

WHY
• How to describe ”User Needs”– Deductive method– Inductive method
• Based on the inductive method– A Case Study– A Network of Processes– A Critical Path

Sustainable Spatial Development
• Sustainability– The current Paradigm for the Development of the EU?
• To integrate:– Natural Information– Artificial Information – Socio-Cultural and Economic Information

A Critical Problem
• Proper descriptions depend on functional and structural:– Outer delineations– Inner differentiations
• Of urban areas– Residential – Work– Civic life– Recreation– Access

WHAT
• A practical solution– The sandwich method
• To integrate– Descriptive information– Analytic information

Data Capture & Spatial Analysis
• A Production Process involving– Data– Features– Method

Area-based Analysis
• Clustering (on irregular tessellations)• AZM (Automatic zoning method)

Point-based Analysis
• Isarithms (on regular tessellations)• Fixed Krieging

HOW
• Step1: A well founded proposal for discussion– Tandem l– Tandem ll
• Step 2: A prototype for benchmarking
• Step 3: A product for implementation

The Proof of the Apple is in the Eating
• Utility• Theoretically argued• Empirically founded• Logically consistent• Open to public discourse (Repeatability)• Accumulative
