Survey type
Sample survey.Survey method
The survey is conducted using face-to-face interviews. In 2013, the interviewers on Saba and Saint Eustatius used paper questionnaires in Dutch, English, Spanish and Papiamento. The answers of the respondents were filled in on the paper questionnaires by the interviewers and were later processed electronically. In 2013, half of the interviewers on Bonaire also used paper questionnaires. The other interviewers used an electronic questionnaire on a tablet. In 2017/2018, interviewers on all three islands conducted the interviews face-to-face using a tablet.The questionnaires of the Omnibus Survey in the Caribbean Netherlands 2013 and of the Omnibus Survey 2017/2018 are available underneath.
Respondents
Persons in private households.Sample size
In 2013, the sample size was 1264 persons on Bonaire, 299 persons on Saba and 330 persons on Saint Eustatius. In 2017/2018, the sample size was 1680 persons on Bonaire, 477 persons on Saba and 620 persons on Saint Eustatius.Checking and correction methods
The figures are checked for internal consistency and completeness.Weighting
A correction is applied to control for differences between the sample and the population. For this purpose a weighting factor is used. The weighting is performed separately for each island. For Bonaire and Saint Eustatius the weighting is based on sex, age, and district. For Saba the weighting is based on sex, age and neighbourhood. For Bonaire the effect of the different interview methods (tablet versus paper) has also been discounted in 2013.Quality of the results
Accuracy
As the survey is based on a sample, the results will fluctuate because of random errors. The reliability margins of the figures are shown in the StatLine tables. Figures are not shown if the number of respondents in a classification category is lower than 50, because in that case the standard errors are considered to be too large. In addition, if the reliability margin is larger than the average or the percentage, the results are not presented.Quality strategy
The interviews for the Omnibus survey are conducted by temporary interviewers who are hired and trained especially for the Omnibus survey. Part of the interviewers have previously worked on other surveys of Statistics Netherlands. The interviewers participate in a two-day course on the content and importance of the Omnibus survey and on interview techniques. In addition, persons who are selected for the survey receive a letter and a folder with information on the Omnibus survey.Downloads
