Table 1 presents the numbers of live births and stillbirths after 23 weeks of gestation in the provinces of Groningen, Friesland and Drenthe. This is the ‘catchment area’ of Eurocat, representing approximately 10% of all births in the Netherlands. The data were obtained from Statistics Netherlands (CBS) and are used as denominators for the calculation of prevalences.

Table 2 shows the number of children registered at Eurocat, by year and type of birth. Since 2010 there is a change in procedure. From this year onward, limited data on diagnosis and birth outcome of children whose parents do not respond to requests to participate were also registered.
The decline in numbers in the most recent years is largely caused by incomplete registration of all cases for these years. This can have a number of reasons:
