  2. Overview • Comparability of results • Margin of error • Availability of data and dissemination

  3. Were the results of the survey compared with data on crimes reported to the police?

  4. Rates per population of selected crimes 436 data are given on 1660 possible data (26%)

  5. Rates per population of selected crimes • Problems: - Period reference ? - Comparability ? - per household or per owner ? - 0.09= 0.09% or 9% ? - etc.

  6. If the survey results have been made public, what margin of error was adopted in presenting the results? 33 relevant information in 78 surveys (42%)

  7. Types of margin of error

  9. Margin error adopted by the ICVS

  10. Is there a public use microdata file?

  11. Are survey results available on internet?

  12. Were printed reports published with the results of the surveys?

  13. Conclusion (1) • Comparability of the data1. with police data 28% of surveys but 53% of countries (63% of surveys in 88% of countries in dark figure/unreported crime, but only 28% of surveys compare with police data)2. with other surveys: lack of comparison

  14. Conclusion (2) • Comparison of data collected between different surveys?Possible if at least:- same methodology- same reference population, rates per owner/pop, etc.Possible in two ways for international comparison:- ICVS- comparison of two surveys (complicated)

  15. Conclusion (3) • Margin of errorShould we propose a model?

  16. Conclusion (4) • Dissemination of results1. on internet(65% of surveys, 78% of countries) = good2. printed version(67% of surveys, 94% of countries) = ok for countries, lack of finalization for surveys
