After the war , Amsterdam became a center of tolerance and culture ; to be different is not abnormal in Amsterdam . Colloquially , some areas within the municipality , such as the village of Durgerdam , may not be considered part of Amsterdam . Statistics Netherlands uses three other definitions of Amsterdam : metropolitan agglomeration Amsterdam ( Grootstedelijke Agglomeratie Amsterdam , not to be confused with Grootstedelijk Gebied Amsterdam , a synonym of Groot Amsterdam ) , Greater Amsterdam ( Groot Amsterdam , a COROP region ) and the urban region Amsterdam ( Stadsgewest Amsterdam ) .
