People’s relative proximity or accessibility to essential services and institutions significantly affect their outcomes as those who are in locations that are more accessible will be able to reach activities and destinations faster than those in inaccessible locations (Rosenberg, 2018). Accessibility to food service facilities have health and survival implications, especially for children and low-income people whose means of transport are limited. The main objective of this research is to use the two-step floating catchment area (2SFCA) method to identify different levels of accessibility and disparities in people’s accessibility to a range of food service facilities in Toledo, Ohio. I also explore relationships between accessibility and observed socioeconomic and demographic factors. I implement a series of exploratory spatial data analysis using 2015 American Community Survey (ACS) block-level data in addition to location information of food service facilities. My analyses reveal that Ottawa Hills assumes the center of the accessibility index. Therefore, gets the highest accessibility score. This research provides a good spatial perspective about the nature of food accessibility in the city, in addition to setting the research agenda to further explore the implications of inadequate accessibility to food service facilities. The research also has implications for public health policy making in the city. The main limitation of the research is the lack of regression analyses to quantify the relationship between accessibility and the socioeconomic and demographic factors. That is beyond the scope of this paper.
