Issues when integrating data sets with different unit types
Inventory of issues that occur when one aims to link and combine data sets with different unit types
Output of official statistics is increasingly based on integration of different data sources. From 1996 onwards a System of social statistical datasets has been developed at Statistics Netherlands that aims at the fast integration of survey and administrative data on persons and households. SN has not been able to develop a similar system for the fast integration of economic datasets for tailor-made publications. One of the reasons is that economic data concern all kinds of different unit types that may be difficult to integrate with each other. The aim of the present paper is to give an overview of the kind of issues that might occur when one tries to compile new publications, in a reasonably short period of time, that concern integrating data sets with different unit types or with unit types that are of a composite nature.
