Events What are they? Why do we need them? On which units?
Types of events Why do we need them? On which units? How can we deduce them? An example Datamodel
4
Events What are they? Events are happenings!
Statistical events are events on statistical units
5
Events Why do we need them? Demography for business statistics
Checks in the statistical process

Events: example “merger”

Types of events m\n 1 >1 - Birth Death Characteristic Change
1 >1 - Birth Death Characteristic Change Split-off Change of ownership Break-up Take-over Restructure Merger

How to deduce events? (1) There´s not only one method! Our method:
Create new preliminary statistical units from changes in legal units Form a file of all units that are/were related to each other. Relations: LU-EG, LU-ENT, ENT-EG, LU-LU (control) Trace all pure births
9
How to deduce events? (2) Our method: … Trace all pure deaths
Trace all characteristic changes Name the remaining event
