How does zip code affect education? The distinct geographical location can actually have a big impact upon the education of an individual, particularly in urban areas. In large metropolitan centers such as New York City, the quality of education very much depends upon zip codes, and also in the case of New York City, there are different parameters such as the specialized high school admissions regulations, which may include submitting artistic portfolios for high schools such as LaGuardia, or submitting technical testing scores for schools like Stuyvesant High School or Brooklyn Tech.
New York City is an interesting example when looking at the public, specialized high school system that is in place there. However, it also becomes useful to study the way in which the educational system is structured in other places, too. This, then, brings up the example of the state of Connecticut. In Connecticut, towns and school districts are often divided by narrow geographic boundaries. This means that a child’s mailbox can determine which public school they attend and, ultimately, what opportunities are available to them.
Connecticut’s education system is particularly vulnerable in this problem because it relies heavily on local funding. In 2017, 58% of Connecticut’s public school funding came from local revenues, the fourth-highest percentage in the country (Zhao and Chiumenti). This system creates an important distinction between communities with substantial property wealth and those without it. As the research on the disparities between Connecticut’s school districts describes, this “creates disparities in education quality between property-rich school districts” and property-poor ones. In the end, it creates a paradox, where public education, which is supposed to provide opportunity regardless of where a child lives, the quality and cost of providing that education can vary dramatically from one district to another.
The differences also come from how much it costs to provide students with the same educational opportunities. Zhao and Chiumenti analyzed Connecticut school districts and identified four factors that increase the cost of education: poverty, the percentage of students living in single-parent or non-family households, small enrollment, and whether a district is regional (Zhao and Chiumenti). The issue is that these factors are largely outside the direct control of local school officials.
The research dives into the cases of Hartford and New Canaan. In 2013, Hartford had a cost index of 1.54, meaning its cost per student was 54% higher than those of the average Connecticut district (Zhao and Chiumenti). New Canaan, meanwhile, had a cost index of 0.82, which is about 18% lower than the average (Zhao and Chiumenti). This difference was not because Hartford students were inherently more expensive to educate. Rather, Hartford had substantially higher levels of poverty and the number of students living in single-parent or non-family households, factors that the researchers found increase the resources required to reach the same level of student performance (Zhao and Chiumenti).
A story by Saundra Foster, a Black single mother living in Hartford, raised the stakes of realizing such problems. Foster believed her teenage son, Trevor, was capable academically more than what his school was offering him, noting that it was “‘almost impossible’” to get him into more rigorous classes (Iorio et al.). He was eventually referred to an alternative education center, and he began to consider dropping out of school. This meant that she had to find an alternative, which was to send Trevor to a suburban school outside Hartford. Yet the consequences of this was severe as suburban districts called students like Trevor “‘line jumpers’” and could attempt to disenroll them when they discovered they were living outside the district (Iorio et al.). Eventually, the Bloomfield police arrested Foster and three other parents, charging them with first-degree felony larceny for “stealing an education” (Iorio et al.). The arrests drew national attention because charging parents criminally for enrolling their children in another public school district was unprecedented.
The problem extends beyond Hartford: school districts with the lowest socioeconomic status and highest level of student need had average education costs 62% higher than districts with the highest socioeconomic status and lowest student need (Zhao and Chiumenti). More than half of Connecticut’s public school students were also attending districts where spending was insufficient to meet the researchers’ estimated costs for reaching the statewide average student performance level (Zhao and Chiumenti). All together, these numbers suggest that educational inequality should be addressed by asking whether schools have enough resources for their students.
But why are there lines in the first place? Its answer goes back to the twentieth century. In Connecticut, school district boundaries often follow town boundaries. And these boundaries were created by housing policies, racial discrimination, zoning, and suburban development of the twentieth century. These factors determined who could live in particular communities creating racially and economically segregated housing patterns (Iorio et al.).
After World War II, families increasingly began to choose where they lived based on the schools their children could attend. Real estate interests, suburban governments and homebuyers converged around the idea that a house was valuable not only because of the house itself, but because of the public school attached to its address. This then led to a universal formula that when you buy a home in the right neighborhood and send your children to the right school, this increases their chances of getting into a good college and eventually help them enter the middle class (Iorio et al.) This idea ultimately makes the ZIP code a gateway into opportunities as a family that can afford a home in a wealthy district may gain access to a school with better demographics, better financial resources, and better educational opportunities, whereas a family that cannot afford that home may have no choice but to send their children to the school assigned to their own district.
To solve the problem, Connecticut has attempted to weaken the connection between housing and education. To address the inequalities created by the existing housing-school system, Connecticut established programs like interdistrict magnet schools and public school choice programs to allow some students to attend schools outside their home districts without requiring their families to purchase or rent a home in those communities (Iorio et al.)
Even this solution, however, hit some limitations. Participation in Hartford-area school-choice lotteries didn’t seem to be completely random. English-language learners and students with special needs participated at lower rates compared to students from more privileged backgrounds, those with higher median household incomes, or those with higher standardized test scores (Iorio et al.).
Even though a zip code cannot determine a student’s intelligence, motivation or potential, it can certainly determine the school district they live in and that district can shape the resources available to them. Zip codes in wealthier areas of the United States, for instance, means that those higher tax dollars then go towards more school resources than zip codes in less wealthy areas. It then makes sense for instance why parents would want to cross geographical boundary lines and integrate their children into schools in wealthier zip codes.
None of this implies that a student’s ZIP code determines their future. Students can still succeed in schools even with fewer resources and students in wealthy districts can struggle the same as teachers, families, peers, and individual circumstances all shape educational outcomes. However, location can still influence the opportunities available to students, and society and policymakers should not neglect this fact.
