This template gives the land area in km2 of each municipality as text output based on the CBS code or name of municipality. It is used as follows:

{{Dutch municipality land area|XX}}

with XX the CBS code, for example: {{Dutch municipality land area|1680}} → 276.09
or the name, for example: {{Dutch municipality land area|Aa en Hunze}} → 276.09
Each municipality has a code assigned by CBS, see List of municipalities of the Netherlands for an overview.

The data in this template can be updated from time to time with new up-to-date CBS stats. Note that a similar version exists for the Dutch language Wikipedia and that the actual data can be updated in the same manner for both versions.
