Three correspondence files are given below:

The Dissemination Area correspondence file is a tabular product that describes the relationship between the 2006 Dissemination Area and the 2001 Dissemination Area;
The Dissemination Area and Land Area correspondence file describes the percentage of the 2006 Dissemination Area’s land area within the boundaries extent of the 2001 Dissemination Area;
The Dissemination Block correspondence file describes the relationship between the 2006 Dissemination Block and the 2001 Dissemination Block.

Each file controls a unique identifier for the present-day count geographic area and the corresponding specific identifier for the early count geographic area. In addition, a relationship flag is added which indicates the degree of correspondence among the geographic fields, helping the comparison among census years.
