Linking of immigrant flow and stock data in the Netherlands; present and future possibilities.
The authors examine ways currently under consideration to link data on the resident population and on immigrants in the Netherlands. "An important development is the introduction of a new computerized population registration system in the near future. One of the features in the new system is that each inhabitant will be identified by a unique identification number. This promises well for opportunities in matching data at the individual level. It is therefore expected that in the new situation it will be possible to better link immigrant stock and flow data."
