The segment of the population between 35 and 64 years of age are considered the population in the latter half of their working life. They have, for the most part, finished having children, are in the upper end of their earning potential, children are leaving the nest, mortgages are paid and assets are increasing. This map exhibits a few interesting patterns when compared with other maps in the age structure. Compared to the early working years group, the later working years segment is less concentrated in the inner parts of the city. Higher proportions are evident on the census subdivision layer in areas outside of cities reflecting past suburban migration patterns. In the north the area outside the populated places is dominated by a high proportion of people in their later working years. Note that very small populations exist in many large census divisions and subdivisions in the North.
