Lifestyle Survey Toolkit


The costs of a lifestyle survey will vary depending on a number of factors including the length of questionnaire, the sample size and methodology used.  The table below illustrates the broad costs for a survey of 1000 completed questionnaires..


Approximate Cost of Survey of 1000 Completed Questionnaires


5,000 - 10,000

Telephone Interview

8,000 - 15,000

Face-to-Face Interview

12,000 - 50,000

Web-Based Survey

3,000 - 8,000

Clearly costs will vary greatly, and will be different depending on the organisation used.  Some aspects that increase or decrease costs include:

  • Complex questionnaire design will increase costs
  • Comprehensive reporting of the survey findings will increase costs
  • the number of questions or, more precisely, the number of variables in the questionnaire
  • the number of open-ended questions
  • the number and type of reminders used in a postal survey
  • the sample design used, particularly in face-to-face interview surveys.  Here, cluster sampling allows for more efficient data collection (but note, it increases sampling error).
  • the need to include 'hard-to-reach' groups in the survey
  • the response rate - a higher response rate is our objective, but it does increase costs, particularly data entry costs (but also survey materials and postage).
