Disposition l.jpg
Disposition enterprise surveys – The Swedish experience

  • Background (The SIV tool and general strategies)

  • Experience (take-up and efforts to raise it, re-design, data quality – a few case studies)

  • Conclusions

ICES III - Johan Erikson


The siv tool l.jpg
The SIV tool enterprise surveys – The Swedish experience

  • Generalised tool

  • Form construction, Administration, Security, Presentation on web

  • Data base solution, pages generated ”on the fly” one at a time

  • Dynamic in all aspects (pages, questions, rows and columns)

  • Developed 2004-2007 (ongoing)

  • Used for both enterprise surveys, household surveys, surveys to agencies and municipalities

  • Will be integrated to have three presentation tools: web, windows form (for telephone interviews), hand-held computers

  • Up to now: used in 40+ enterprise surveys, 100+ surveys in total

ICES III - Johan Erikson


General strategy l.jpg
General strategy enterprise surveys – The Swedish experience

  • Defensive strategy

  • Paper form + opportunity to reply on the web

  • Log-in information normally placed on the paper form and not on the cover letter

  • Web questionnaires slightly re-designed to fit screen size rather than paper size

  • Dynamic when possible (skip patterns, add rows and columns when necessary)

  • Some (but mostly simple) edit checks

  • Reminders – some have new paper form, some do not

ICES III - Johan Erikson


Take up l.jpg
Take-up enterprise surveys – The Swedish experience

  • With general strategy – take-up varies from less than 2% to more than 40%

  • Normal take-up: 5-20%

  • Surveys with high take-up: register updates, surveys that have had TDE as an option

  • Take-up in monthly surveys: stable or rising

  • Possible effort to raise take-up: No paper questionnaire (ordinary sending or reminder)

Efforts to raise take up l.jpg
Efforts to raise take-up enterprise surveys – The Swedish experience

  • ”LINDA” survey – wages (november) for specific individuals (longitudinal survey) – not all employees

  • Normally, 1-10 individuals per enterprise

  • Almost 29000 enterprises (27500 have 1-3 individuals)

  • Experiment: 20 per cent of enterprises 1-4 indivisuals and 100% of enterprises 5-10 individuals were sent no paper questionnaire (will be sent at reminder, when the others will not be sent a new paper questionnaire)

Efforts to raise take up9 l.jpg
Efforts to raise take-up enterprise surveys – The Swedish experience

  • Development of new enterprises

  • Experiment: No new paper form at reminder, extra push for web

ICES III - Johan Erikson


Efforts to raise take up10 l.jpg
Efforts to raise take-up enterprise surveys – The Swedish experience

  • The big step – eliminating paper forms

  • 3-4 surveys

  • Most enterprises use web when it´s the option given

  • Paper form when active effort (phone call)

  • Some extra efforts have been made on reminders

  • Response rates have varied, from no change to small dips

ICES III - Johan Erikson


Re design l.jpg
Re-design enterprise surveys – The Swedish experience

  • Web as a third alternative – turnover statistics

  • Before: paper/TDE Now: paper/TDE/Web

  • Only one indicator (turnover)

  • Monthly/quarterly statistic

Data quality l.jpg
Data quality enterprise surveys – The Swedish experience

  • Data is scarce

  • Based on editing after collection

  • Ratio of objects showing at least one error signal

  • Remember: not many edit checks in web questionnaire

  • But: elementary edits (format, radio buttons allowing only one mark, automatic skip patterns) eliminate some errors

  • Tendency is similar regardless of type of survey – ratio of objects with error signals is lower for web

  • Slight but slow tendency of error rates to decrease over time

Conclusions l.jpg
Conclusions enterprise surveys – The Swedish experience

  • Take-up with defensive strategy is rather low

  • Take-up-rates may be influenced significantly

  • Not sending paper questionnaires may reduce response rates

  • Offering web as an alternative can raise electronic share of responses even when TDE is used as well

  • Data quality tends to be somewhat higher on web than on paper – mostly because simple errors can be eliminated
