- Strategies to improve list-based sampling by : automatically updating the sample frame using administrative registers, using common samples with other surveys, and by using administrative information to improve stratification in sample design.
-Data collection strategies to shorten response delays : by simplifying the questionnaire, reducing the number of data items, and/or breakdowns requested, consistent with the user’s needs for statistics, by using web based questionnaires, computer assisted interviewing, incorporating statistical programmers in accounting software, sending questionnaires early to economic units, and setting deadline to coincide with deadlines set for respondents, following up the larger non-respondents first, or those in essential industries or regions, as they have a more important bearing on global estimates.
- Strategies to reduce non-response : by reporting back to the units in the sample, with results from the survey to signal the situation of their unit relative to that of other units in the same market or industry
