CBS Quality Indicators • Timeliness and punctuality – Timeliness reflects the length of time between its availability and the event it describes – Punctuality refers to the time lag between release date of the data and the target date the statistical information should have been delivered • Processing and completion of survey may take more time than expected • Accessibility and clarity – The possibilities to obtain the data – Use of graphs, illustrations, or metadata • CBS delivers its statistics in either digital and hardcopy formats • Data availability on the website: www.cbs.an

CBS Quality Indicators • Comparability – To measure the impact of differences in applied statistical concepts and tools when statistics are compared between geographical areas or over time • Use of time series to compare national accounts data • Coherence – Adequacy to be reliably combined in different ways and for various uses • CBS uses international definitions and standards for the compilation of statistics • By integrating and balancing the data CBS is able to use different data sources to produce statistics
