How is the survey conducted?
Type of survey
The source for the price index figures is the registration of house sales in the period mentioned above. This registration provides data on sales of new and existing dwellings, whether purchased or sold by a private individual, a commercial party or otherwise.
Statistics Netherlands receives the data in a digital format.
The relevant data are obtained from the Tax Authority of the Caribbean Netherlands. Primary transaction data, such as purchase date and amount involved are based on Bonaire’s Land Registry Office. Additional features of the dwelling are provided by the administration of the Tax Authority.
On an annual basis, more than 150 dwellings are sold on Bonaire. All these transactions are covered by the survey.
Control and correction methods
After receipt, Statistics Netherlands will check completeness and plausibility of the data. Data which appear to be incorrect or incomplete are verified. Some transactions with a disproportionate effect on the results are excluded from the index calculation.
Quality of the results
The accuracy of the price index is safeguarded by complete (integral) observation, by observation over a longer time period and by the calculation method, but the degree of accuracy cannot be calculated.
The survey results are comparable in time.
Description quality strategy
Data are checked for internal consistency and completeness. Wherever necessary, action is taken to verify data. Subsequently, price indices are calculated and the results are verified and validated. Validation of the calculation method and results are not done by the same person who carried out the calculations.
