Regular versus eventdriven

Faster figures
– Nowadays people want to be informed in a fast way about events in the society
– Statistics Netherlands provides daily information on our society
– However not related to current events – In a Proof of Concept it is shown the possibility to
respond to current events in a statistical process
4
Proof Of Concept (POC)
– Events (administrative events): daily entry and exit-registration of companies at the Chambers of Commerce
– Statistical Process: compilation of the economic demography, being redesigned from yearly survey to a yearly/quarterly statistic based on registerdata, mainly on the General Business Registry (GBR)

Process

Research input ↔ output
– Input → output relation administrative events and entries / exits in the frame – Output → input entries and exits in the frame with/without relation to Single Business Register (SBR)

Conclusion
– Administratieve events are usuable in event driven processing
– Possible to improve the timeliness dramatically – Quality can be improved by fitting the estimation model
and/or by adding new types of events
