Figure 1.11 Example of a merged census metropolitan area (CMA) and census agglomeration (CA)

Description of Figure 1.11

Figure 1.11 is a graphical representation of an example of a census agglomeration (CA) that has merged with a census metropolitan area (CMA). A fictional grouping of census subdivisions (CSDs) that make up a CMA are shown as polygons.

The polygons that make up the original CMA are shaded dark grey. Inside this grouping is a polygon shaded with dotted lines that represents the core of the CMA. A smaller polygon shaded with vertical, varied lines also exists in this grouping that represents a smaller population centre within the CMA, known as fringe.

The polygons that make up the CA that merged with the CMA are shaded light grey. Inside this grouping is a grey polygon with varied horizontal lines that represents the secondary core of the CMA. This was the former CA core.

A thick black line outlines the perimeter of all the CSDs to identify the boundary of the CMA.

An arrow outside the boundary of the CMA extends from the dark-shaded polygons to the light-shaded polygons to represent the total employed labour force living in the CMA and working in the CA (3,150). Another arrow outside the boundary extends from the light-shaded polygons to the dark-shaded polygons to represent the total employed labour force living in the CA and working in the CMA (350).

An equation is shown under the second arrow to illustrate how the total percentage commuting interchange between the CA and CMA is calculated in this example. The sum of these two populations, 3,500, is divided by the resident employed labour force of the CA (10,000) and multiplied by 100 to equal a 35% interchange.

The calculation of the employed labour force excludes the category of no fixed workplace address. Moreover, all calculations of commuting exclude data on no fixed workplace address.

A legend appears below the figure to identify the symbols used in the figure for representing the CMA, the CA, the new CMA boundary, and the boundaries of the CSD, population centre, core, secondary core and fringe.
