On 1 January 2011, there were 418 municipalities in the Netherlands versus 431 on 1 January 2010. This downward trend has been going on for many years; the aim of reducing the number of municipalities is to strengthen the administrative power at the municipal level.
17 municipalities abolished
On 1 January this year, 17 Dutch municipalities across 6 provinces, were abolished. These municipalities were included in 3 already existing and 5 newly created municipalities. On 18 March 2010, Rozenburg was included in the municipality of Rotterdam. Altogether, 13 municipalities were abolished and the Netherlands comprises 418 municipalities on 1 January 2011.
136 municipalities have not been subject to redivisions
A total of 277 municipalities in the Netherlands already existed prior to 1900; 136 of these municipalities have never been involved in a redivisions process, but that does not imply that there have never been changes. Nearly all municipalities have been subject to boundary changes.
The remaining 141 municipalities were created after 1900 as a result of mergers in combination with name changes or only the name has been changed. In the province of Friesland, many municipalities were henceforth denoted by their official Frisian name.
