UNECE Statistical Division Helsinki, 9-11 February 2005

National surveys in the international context Methodology: Population

  • USA: 12 years and over
  • Italy: 14 years and over
  • Australia: 15 years and over (NCSS)

UNECE Statistical Division Helsinki, 9-11 February 2005

National surveys in the international context Methodology: Population

  • Data can be provided for a common

population (15 years and above)

  • Guidelines on how interviewing

minors (domestic violence?)

National surveys in the international context Methodology: Reference Period

  • USA: 6 months
  • Italy, UK: 12 months
  • Australia: 12 months (NCSS)
  • ICVS: 3-15 months

UNECE Statistical Division Helsinki, 9-11 February 2005

National surveys in the international context

Methodology: More then a common reference period: How to deal with the Telescoping effect

  • USA: Bounding and reducing the reference

period

  • Italy: funnelling + recording month and year
  • f the last event

How many cases the bounding corrects for? Are two consecutive surveys enough for bounding?

UNECE Statistical Division Helsinki, 9-11 February 2005

National surveys in the international context

Methodology: Survey Mode

  • USA: personal interviews + CATI
  • Italy: CATI
  • Australia: self-compilation, face-to-face

interviews + telephone interviews (if respondent requests)

  • ICVS: CATI

To have the respondent alone is an issue

National surveys in the international context

Methodology: Questions design Put the survey in a context Improvement of the screening to help the respondent to recall and understand the type

  • f crime (give examples of places and

circumstances) Improvement of the screening for sensitive crimes

slide-13
SLIDE 13

UNECE Statistical Division Helsinki, 9-11 February 2005

National surveys in the international context

Where to go?

  • Compare methods, definitions, coverage of

crimes

  • Explore the possibility to develop a common

minimum set

  • Develop international/regional guidelines
  • Include victimization surveys into the agenda
  • f official statistics
slide-14
SLIDE 14

UNECE Statistical Division Helsinki, 9-11 February 2005

National surveys in the international context

Needed Guidelines

  • Telescoping
  • Mode of survey (personal contact, respondent alone)
  • Reference period
  • Question design (particularly for sensitive topics such as

sexual assault)

  • Interviewer effect (male/female interviewers)
  • Definitions of crime
  • Consumed/attempted crimes
  • Definition of reporting crimes
  • Non responses
  • Sampling
  • ………
slide-15
SLIDE 15

UNECE Statistical Division Helsinki, 9-11 February 2005

How far can we go?

  • Is it possible to identify common

definition of (some) crimes covered by national surveys?

  • Is it possible to agree on a common

reference period (question validity/coverage of crimes)?

  • To keep the national specificity and

provide a minimum set of comparable data (learning from the ICVS)?
