Observation 1 l.jpg
Observation (1)

When the main (or sole) user of the statistics is also the only provider of the data the statistics are based on, there is less need for a central statistical bureau for these statistics


Main characteristics10 l.jpg
Main characteristics

  • (Too) many statistics

  • Isolated statistics


Example 1 l.jpg
Example 1

The policy program: towards a safer society

Precise targets:

  • Reduction of crime in public spaces

  • Opinion of police and feelings of safety

  • Repeat offenders


Observation 2 l.jpg
Observation (2)

It can be very dangerous to make statements on the success of policy measures based on outcome statistics alone


Example 2 l.jpg
Example 2

Modelling the Criminal Justice system

  • Econometric model, based on aggragate statistics

Example 215 l.jpg
Example 2 volwassenen, versie 1.1

Modelling the Criminal Justice System

  • Econometric model, based on aggragate statistics

  • Also external factors

  • Knowledge of the working (the expected behaviour) of the Criminal Justice System


Observation 3 l.jpg
Observation (3) volwassenen, versie 1.1

Integrating different areas of Crime Statistics and Statistics from other areas, even if this integration is on an aggragate level only, is very useful in observing the working of the Criminal Justice System as a whole and the expected outcome of specific policy measures


Example 3 l.jpg
Example 3 volwassenen, versie 1.1

Offenders from ethnic minorities

  • Offender data are linked (on individual level) with demographic data. This gives information on ethnicity

  • These data are linked to other social and economic statistics

  • Helpful for implementing specific policy programs


Observation 4 l.jpg
Observation (4) volwassenen, versie 1.1

Integrating Crime Statistics on an individual level with statistics from other areas is very useful in understanding crime related phenomena and in formulating specific policy measures

Main conclusions l.jpg
Main conclusions volwassenen, versie 1.1

The big challenge in the coming years is integration of statistics, preferably on an individual level. Within the different areas of the Criminal Justice System, but also with other (demographic, economic and social) statistics.


Main conclusions cont l.jpg
Main conclusions (cont.) volwassenen, versie 1.1

This in order to get a better understanding of the working of the Criminal Justice System itself and the influence of external factors. Only then a fact based policy making is possible. To achieve this a central statistical bureau, having access to statistics in different areas is very important.
