Joining statistical data to UMZ:Urban Audit and Census

Urban Audit Census

Data collection Every 3 years Every 10 years

Coverage Most important cities ("importance" is arbitrarily decided by MS) in four levels: Subcity Districts, Cities, Kernels and Large Urban Zones

All communes

Partial collection of variables for all cities with more than 100 000 inhabitants (Large City Audit)

Variables 344 variables (53 for LCA) about 60

Subject Population, Social Statistics, Employment, Education, Environment, Transport, Information society, Culture

Population, Labour force and education, households and dwellings.

Coding system

Urban Audit:- ad hoc coding: Brussels =

BE001C, BE001L- All cities, LUZs and LCAs are

built up by using communes as building block (i.e. administrative boundaries, and not urban morphological zones)

- It is possible to link UA cities with communes in a perfect 1 to many relationship.

Link statistical data to UMZ:

- Data collection (census and UA) is bound to administrative boundaries.

-Tabular approach can only be weighted:- by area- by population (by means of

dissagregation grid)

(how to deal with variables like “residents in self employment” or “students leaving compulsory education without having a diploma”?)



-Approach UA to UMZ or viceversa?:

Rather than bringing UMZ to the tabular world, GISCO is very interested to bring census and UA to the spatial world by means of UMZ and the population grid:

- New variable in UA: Max and min height of the UMZ inside a city.

- Definition of LUZ and cities
