Cascadia Age Ranges
The amount of people that fall within three age ranges in U.S. Counties and Canadian Census Divisions within the Cascadia bioregion.
The three age ranges symbolized in this project represent people under 18, age 18-64, and age 65 and older.
The map to the right represents the 18-64 age group, which is the largest of the three. As this age group contains the most people, darker areas reflect areas of Cascadia with the greatest populations. The darkest blues in the map are found at the bioregions largest population centers. For Washington these are King, Snohomish, and pierce counties which represent the most urban section of the I5 corridor. Additionally, the Vancouver census divisions are symbolized with dark blue reflecting the most populous region of B.C.
The under 18 age range represents a much smaller portion of the overall population. As a result, counties and census divisions symbolized with darker blues reflect ares with particularly large youth populations. High youth populations area obviously found in the areas with overall large populations, but the density of youth populations is more spatially varied than the broader 18-64 category.
The map to the right shows data for the 65 and older population of the Cascadia bioregion. Like the under 18 map above, the 65+ population is a small chunk of the overall population so dark blue areas represent locations with particularly high older populations. Again, locations with large overall populations, like the Seattle or Vancouver metropolitan areas, will inevitably have high counts of any age range. The map to the right shows that there are few locations within Cascadia with particularly large elderly populations. Most of these are confined to the western edge of the region to the west of the Cascadia Mountains. This pattern is likely aided by the more temperate climate that can be found close to the Pacific.
The graph to the right shows a comparison of the age ranges for the 5 most populous counties/divisions of the Cascadia Bioregion. This display allows for comparison of the age distribution of these heavily populated areas.
