Kass's Six Questions Applied to a City's Proposed Buffer Barring New Fast-Food Outlets Within a Quarter Mile of Schools, With a Verdict That Depends on What the Evidence Can Bear

Introduction

A composite mid-sized city is considering a zoning ordinance that would bar new fast-food restaurants from opening within a quarter mile of any public school. Existing outlets would be grandfathered. Supporters frame it as a measure against childhood obesity; opponents call it ineffective and a burden on small businesses in neighborhoods that need them. This paper applies the six questions Kass (2001) proposed for public health ethics, one under each heading, and ends with a verdict whose conditions follow from the answers. The city exists only on the page; evidence on effects comes from published evaluations of real policies, reported as findings.

1. The Program's Public Health Goals

The stated goal is to reduce children's consumption of energy-dense, low-nutrient food during the school day and on the walk home, and through that, to reduce obesity and diet-related disease over time. Kass asks that goals be stated in terms of health rather than behavior alone. Reducing fast-food visits is a means; the end is healthier weight trajectories and lower future risk of diabetes and heart disease. Naming the goal this way matters, because a measure that shifted purchases to convenience stores selling similar food would meet the behavioral target and miss the health one.

2. Effectiveness Toward Those Goals

The evidence is mixed and the answer must say so. Observational studies have found that students whose schools sit close to fast-food outlets are more likely to be overweight. One California study found higher overweight prevalence among students at schools within half a mile of a fast-food restaurant (Davis & Carpenter, 2009), and an analysis of ninth graders found that a fast-food restaurant within a tenth of a mile of a school was associated with higher obesity rates (Currie et al., 2010). A systematic review of fast-food access, however, found inconsistent associations overall, with stronger findings near schools than near homes (Fleischhacker et al., 2011). The direct test of a zoning approach is discouraging: an evaluation of the moratorium on new standalone fast-food restaurants in South Los Angeles found no measurable effect on diet or obesity in the years that followed (Sturm & Hattori, 2015). Because existing outlets would remain, the ordinance would act slowly, only on future openings.

The honest answer to the second question is that the measure's effectiveness is plausible near schools but unproven, and the closest real-world evaluation found no effect.

3. Known and Potential Burdens

The burdens fall on several groups. Prospective restaurant owners, including franchisees and local entrepreneurs, lose the option of opening near schools, which in dense neighborhoods may cover much of the commercial land. Workers lose potential jobs. Residents in neighborhoods with few food options may lose one of the few affordable, quick places to eat. Students' liberty is constrained only slightly, since they can walk farther, but the measure also carries an expressive burden: it implicitly characterizes neighborhoods with many fast-food outlets, often lower-income and with more residents of color, as places whose choices need correcting.

4. Reducing Burdens, and the Alternatives

Several alternatives would impose fewer burdens or act more directly. Closed-campus lunch policies keep students on site during the school day without restricting businesses. Improving school meals targets the same consumption with evidence of benefit. Incentives for grocers or healthier restaurants to locate near schools add options instead of removing them. Within the ordinance itself, burdens could be reduced by narrowing the buffer, exempting restaurants that meet nutrition standards, or applying the rule only to drive-through formats. Kass's framework implies a preference for the least burdensome measure that achieves the goal. Some of these alternatives also carry evidence of their own. Federal school meal standards strengthened in 2012 raised the nutritional quality of what students are served, and closed-campus policies keep younger students from leaving at lunch altogether, which acts on the same exposure the buffer targets during the school day. Incentives to add healthy options work in the opposite direction from the buffer: they enlarge choice rather than restricting it, which matters in neighborhoods where residents already have few places to eat. None of these alternatives addresses the walk home after school, which is the one gap the buffer would fill, and an honest application of the fourth question acknowledges that. Here, several alternatives target the goal at least as directly with less restriction.

5. Fairness in Implementation

Fairness concerns both process and distribution. In many cities, schools and fast-food outlets cluster in the same lower-income neighborhoods, so the buffer would fall hardest there, restricting entrepreneurship and food options in places that already have fewer of both. If the ordinance were adopted without consulting the residents and small-business owners most affected, it would compound that unfairness with a procedural one. A fair process would hold hearings in affected neighborhoods, publish the evidence and its limits, and commit to evaluation.

6. Balancing Benefits Against Burdens

Balancing requires weighing an uncertain, slow-acting benefit against concrete, immediate burdens concentrated on particular neighborhoods. On current evidence, that balance does not clearly favor the ordinance as drafted. It could favor a modified version: a narrower buffer around schools, paired with investments in school meals and healthier food options, a sunset clause, and a funded evaluation of students' diets and weights. That package would reduce burdens, add benefits that do not depend on the buffer's effectiveness, and generate the evidence the city now lacks.

Conclusion

Applying Kass's questions yields a conditioned verdict. The ordinance pursues a legitimate health goal, but its effectiveness is unproven and the nearest real-world test found none, while its burdens are concrete and concentrated in neighborhoods with fewer resources. It is justified only if narrowed, paired with measures that add healthy options, adopted through a process that includes affected residents, and evaluated with a commitment to repeal if no benefit appears. Without those conditions, the city would be imposing certain costs for a hoped-for gain.
