# List of census agglomerations in Alberta

A census agglomeration is a census geographic unit in Canada determined by Statistics Canada. A census agglomeration comprises one or more adjacent census subdivisions that has a core population of 10,000 or greater. It is eligible for classification as a census metropolitan area once it reaches a population of 100,000.
