Slide 3
S tadsmonitor A msterdam What does it bring about? The S
tadsmonitor A msterdam shows spatial concentrations of phenomena.
The monitor shows whether concentrations are persistent or
temporary: spatial dynamics.
Slide 4
example: concentrations of age categories, 1-1-2000 25-54 yr
(green border) and 55+ yr (yellow)
Slide 5
Why S tadsmonitor A msterdam? To show the condition of the city
in various domains of participation in society. To follow a limited
number of spatial processes over a longer time period, in great
detail (city, city-districts, neighbourhoods, street and block
levels)
Slide 6
What are the domains? Demographic basis Housing stock
Population Participation Unemployment Education Benefit dependency
Criminality
Slide 7
S tadsmonitor A msterdam How does it operate? Data at six digit
postcode level First, each six digit postcode is mapped as an area
that encloses the co-ordinates of all addresses. Adjacent areas
that fit the criteria with respect to content, are combined into
concentration areas and mapped. The most important standard for
these constructions of concentrations is percentage-level of the
phenomenon under consideration in the initial postcode area
(frequently from two standard deviations above the mean, but more
critical levels are also allowed).

An example of the construction of concentration areas of a
blown up detail of the city (700x700 meter)
Slide 9
All six digit postcodes in the area
Slide 10
Construction of concentrations of Moroccan households (hh):
only postcodes with at least 12.87% Moroccan hh.(1-1-2000)
Slide 11
Extension of these postcodes with 25 meter around

Slide 16
Areas with low density are removed
Slide 17
Slide 18
Slide 19
Slide 20
Areas are combined in new units: concentration areas of
Moroccan households, 1-1-2000
Slide 21
Slide 22
Some characteristics of the new concentration areas: number and
percentage of Moroccan hh on 1-1-2000
Slide 23
For privacy reasons only new areas with a minimum of 10
Moroccan households are shown
Slide 24
Slide 25
Slide 26
Users may apply additional criteria for the construction of
concentration areas

What are the applications? The S tadsmonitor A msterdam may be
applied for three purposes: Exploration Description of developments
Testing of hypotheses and ideas about spatial concentrations and
developments
Slide 31
Application exploration: example 1 Unemployment An exploration
of the maps with concentrations of unemployment showed us that
there are certain areas in Amsterdam Zuidoost (Southeast) with
concentrations of long-term and short-term unemployed people in
similar areas.
Slide 32
Concentrations of short-term unemployment (yellow), and
long-term unemployment (green borders), 1999
Slide 33
is this a ghetto-area where people cannot escape from? Is there
a specific relation with the urban restructuring policies in the
rest of Amsterdam Southeast? Is the concentration of long-term
unemployed persistent because the residents are unable to improve
their housing situation? Is the concentration of short-term
unemployed persistent because this is the lower end of the housing
market, which attracts marginalized people, who are unable to get a
job, again and again? Additional analyses showed us that these
areas are also characterized by youth unemployment, concentrations
of non- western immigrants, high levels of social benefits,
etceteras. Questions that arise are:
Slide 34
Application: description of a process Unstable Moroccan
concentrations 1996 and 2000 A shift from pre-war areas towards
post-war areas
Slide 35
Concentrations of Moroccans 1996: yellow, 16 areas; 2000: green
borders, 18 areas

Slide 37
Application: testing of hypotheses Some areas are not affected
by even a long period of economic growth; concentrations of people
on social benefits are not in decline everywhere.
Slide 38
Concentrations of people on social welfare 1996 (yellow): 13
areas, total: 3969 welfare recipients 2000 (green borders): 10
areas, total: 2560 welfare recipients
