Socio - economic characteristics
Geographic distribution
All deliveries
For the unmerged stays, these characteristics are not available.
Table X shows that the geographical distribution of the stay of deliveries between
regions and provinces differs between the merged and unmerged data.
In Brussels, the proportion of deliveries with unmerged stays is lower than the
proportion of deliveries with merged stays, while in Antwerpen the proportion of
unmerged stays seems quite high. At present, we do not have clear explanation for that
finding. Exploratory investigations revealed that an hospital located in this province had
none of his 798 merged. However, even after removal of that hospital, the proportion
of unmerged stays in Antwerpen remained high.
Another high proportion of unmerged stays is found in the Luxembourg province
(10.4% of the overall unmerged stays against 2.2% of the overall merged stays). Is this
high proportion explained by the proximity of the border with Luxembourg (country) ?
The higher proportion of unknown place of residence among the unmerged stays is
explained by the fact that the place of residence for these stays is established only by
means of MKG/RCM data, without the possibility of using IMA/AIM data for substituting
the missing data .
