AMI AND KID DENSITY
Primary data was sourced from Pierce County Open GeoSpatial Data Portal and the U.S. Census Bureau
These 3D Isarithmic models represent the density of the population of children under the age of 18 in the city of Tacoma. The darker red areas indicate a lower density of kids while, moving towards the green end of the scale, the population density increases. Figure 2 shows this from a birds-eye-view of Tacoma (Figure 1), overlapped by the varying districts of the city. The trends here show a high density of kids in areas that are in close proximity to major freeways like I-5, I-705, and I-405. The highest areas of kid density are best seen in Figure 3, where major spikes occur in North End, Eastside, and South Tacoma.

Figure 5
The Average Median Income (AMI) of Tacoma is represented by 3D Isarithmic model mapping to illustrate neighborhood concentrations of high or low income earners.
From a birds-eye view perspective, like as in Figure 6, the areas with the lowest income earners are symbolized in red while the highest are in green. For a 3D model such as Figure 4, the low income earners are symbolized by both color and rises and dips in the landscape.
As the same with Figures 1-3 (above), Figure 5 shows the AMI determined landscape as it compares with Tacoma districts. From this map compared with the two others, we can infer that the areas of lowest earning are New Tacoma (Port Subarea), the Eastside, and South Tacoma.
