In this article, I discuss the promise of geospatial techniques for education policy research and how increased attention to the historical context of spatial data can enhance that work. While scholarship utilizing geographic information systems has added considerable breadth to our understanding of education policy, recent geospatial studies in education policy tended to neglect long-term, historical trends. Drawing on research in geography dealing with temporality, this article discusses the critical importance of historical context for spatial analysis. Then, to illustrate this point, I use the example of education policy research on school district boundaries to suggest the benefits of extending our temporal frame when conducting geospatial educational research. Greater attention to the historical context of geospatial data can (1) help policy researchers generate new research questions, (2) enhance their use of quantitative spatial analysis techniques, and (3) deepen their understanding of the underlying causes of contemporary patterns in the distribution of educational opportunity.

This article investigates trends in the relative wealth of the richest school districts in the United States between 2000 and 2015. For the purposes of discussion, I focus on the top 1% of districts. I argue that trends in school funding for the richest districts deserve greater attention from education researchers. Districts in the top 1% of the cost-adjusted, national school funding distribution are disproportionately suburban, affluent, and White. The relative wealth of these districts increased sharply (31.59%) between 2000 and 2015. Disaggregating these trends reveals large variation between states. Nevertheless, resource concentration in the top percentile of school districts increased in a large majority of states. These findings cannot be explained by efforts to provide additional educational resources to students with the greatest needs, and they suggest the ways in which the concentration of affluence accompanying growing economic inequality may be changing school funding.

In the United States, researchers have documented persistent racial disparities in school funding for decades. Drawing on evidence from a recent policy change in Pennsylvania, this article contributes to research on the role of state governments in limiting or expanding racial disparities in K-12 education funding by examining differences in the racial composition of school districts positively and negatively impacted by a technical provision lawmakers inserted into a newly created formula for distributing state equalization aid. We find that negatively-impacted districts enroll a substantially higher number of Black and Latinx students, receive less state aid, have lower levels of state and local funding, and have lower spending levels than positively-impacted districts with otherwise similar financial needs. These findings suggest how state lawmakers can exacerbate racial inequities when pursuing reforms ostensibly focused on equity, and these results have implications for both policymakers and educational leaders focused on racial justice.

Background/Context Dealing mostly in aggregate statistics that mask important regional variations, scholars often assume that district property taxation and the resource disparities this approach to school funding creates are deeply rooted in the history of American education. Purpose/Objective/Research Question/Focus of Study This article explores the history of district property taxation and school funding disparities in California during the 19th and 20th centuries. First, the article documents the limited use of district property taxation for school funding in California and several other Western states during the 19th century, showing that the development of school finance was more complicated than standard accounts suggest. Then, the article examines how a coalition of experts, activists, and politicians worked together during the early 20th century to promote district property taxation and institutionalize the idea that the wealth of local communities, rather than the wealth of the entire state, should determine the resources available for public schooling. Research Design This article draws on primary source documents from state and regional archives, including district-level funding data from nine Northern California counties, to complete a historical analysis. Conclusions/Recommendations The history of California's district property tax suggests the need for continued research on long-term trends in school finance and educational inequality. Popular accounts minimizing the historical role of state governments in school funding obscure how public policies, not just market forces shaping property values, create funding inequalities. In turn, these accounts communicate powerful messages about the supposed inevitability of funding disparities and the responsibility of state governments to correct them. Through increased attention to long-term trends in school funding, scholars can help popular commentators and policymakers avoid assumptions that naturalize inequality and narrow the possibilities for future funding reforms.
