Year-prevalence figures from two Dutch psychiatric case-registers have been compared. Although the findings suggest some remarkable similarities, there seem to exist some differences between the mental health care in both areas.

In general we could replicate our first comparative findings (one-day prevalence). In both areas most people contacted out-patient services, especially the so-called Regional Institutes for Ambulatory Mental Health Care (RIAGG).

The diagnostic distribution showed some differences for the patients who were admitted.
