This paper extends an existing accessibility analysis of Chicago based on the policy platform known as the 15-Minute City, which focuses on proximity of destinations at threshold level (whether categories of destination exist at all within the travel sheds). The author used indexing to compare the metric to an alternative, more complex metric. He then used GIS software and zoning districts to conduct a dasymetric areal interpolation to assign demographic data to walksheds from the original analysis and evaluated potential relationships between level of access and these data. Case studies follow, investigating demographic differences between five contiguous high-access clusters. While the trends that arose suggested that this threshold-focused accessibility metric used has some utility, stark differences between the clusters reinforce that a baseline level of proximity to resources is insufficient for generating equitable outcomes. |
