A story of the struggle against all the zillion of problems you encounter when trying to make crime statistics between countries ‘comparable’ …..
….. and how to succeed …..
...... well, at least partially.

Four research projects
1. EUCPN report: Crime trends in the EU
2. Cambridge study on crime trends
3. Study on effectiveness and severeness of law enforcement
4. Study on detection rates
![Page 6: International Crime Statistics Some recent research experiences](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681459a550346895db28ca0/html5/thumbnails/6.jpg)
EUCPN report: Crime trends in the EU
• Based on existing international datasources (ICVS, European Sourcebook, UK Data Collection, Eurobarometer)
• Comparing trends is probably better than comparing rates.
![Page 7: International Crime Statistics Some recent research experiences](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681459a550346895db28ca0/html5/thumbnails/7.jpg)
Cambridge study on crime trends
• 8 countries, will be published this year in a special issue of Crime and Justice
• National data are used. On a national level the statistics are modified to meet the requirements (definitions imposed)
• All individual country chapters follow the same format

Study on effectiveness and severeness of law enforcement
• Study presented at the ESC (2003) based on European Sourcebook data
• Comparing ratios is probably better than comparing rates.

Study on detection rates
• Was published in the same European Journal on Criminal Policy and Research as the EUCPN study
• Research question: Is the detection rate as published by various countries a good measure of the effectiveness of the police or do other factors also influence this rate?

Method used
• Identify different factors that could, potentially, influence the detection rate.
• Use existing datasources (European Sourcebook, ICVS) and a questionnaire filled in by contacts in the different countries to ‘score’ those factors.
• Analyse the possibility / probability that those factors indeed do influence the detection rate.
