School district secession—a political process forming small, new school systems that tend to serve a higher-proportion White and more affluent residential population than the large districts from which they splinter—has received growing attention in media, legal, and policy circles (
Brown, 2016;
Eaton, 2014;
EdBuild, 2019a;
Hannah-Jones, 2017;
Spencer, 2014;
Wilson, 2016). Although district secessions occur around the country, they are concentrated in the South.
1 Recent Southern secessions reflect a narrowing conception of what is “public” about public education as newly created districts seek to preserve relative racial and economic advantages for more homogeneous White areas (
Siegel-Hawley, Diem, & Frankenberg, 2018). Often couched in the race-neutral rationale of “local control”—language long used by White families to resist school desegregation—Southern secessions raise particular concerns about educational inequity, occurring as they do against the region’s historical backdrop of de jure segregation and subsequent resistance to the
Brown v. Board of Education decision. Research has documented the resegregation of students in the South (
Boger & Orfield, 2005;
Reardon, Grewal, Kalogrides, & Greenberg, 2012), a trend that follows a post-
Brown period when Southern schools became the most integrated (
Frankenberg, Lee, & Orfield, 2003). In a region undergoing rapid demographic change, is contemporary school district secession poised to become yet another tactic in the South’s “sordid history” of White efforts to thwart equal educational opportunity (
Wilson, 2016)? The following study is the first to systematically explore whether and to what extent new school district boundaries increasingly segregate students and residents in the South.
Fragmented school districts have been a phenomenon primarily associated with the Northeast and Midwest (
Bischoff, 2008), but district secession in Southern countywide systems is upending, to some degree, the one-county, one-school-system archetype in parts of the South. The end of court-ordered school desegregation has meant that schools in the metropolitan South, once more integrated than neighborhoods, have lost that distinction (
Reardon et al., 2012;
Reardon & Yun, 2005). Thus, the erosion of the South’s countywide advantage also comes amid the erosion of the region’s schooling advantage—that is, a pattern in which schools are more integrated than neighborhoods.
Despite long-standing White resistance to desegregation, judicial pressure meant that the South’s countywide school systems (or ones that include both cities and suburbs) historically have been some of the most integrated for Black and White students (
Siegel-Hawley, 2016). Countywide systems with comprehensive school desegregation plans also report lower residential segregation because housing choices become—to some degree—decoupled from school choices once all households in a county are part of the same school system (
Pearce, 1980). Families come to understand they can move across the metropolitan area (also referred to herein as “metro”) community and still be connected to a diverse school. By contrast, school and housing segregation tend to be higher in metropolitan areas outside the South where districts are highly fragmented, with single metros containing multiple suburban school systems alongside one or more central-city school districts (
Bischoff, 2008;
Frankenberg, 2009). It stands to reason, then, that the secession of White, suburban municipalities from larger, more diverse countywide systems is therefore likely to impact not only school segregation but also residential segregation.
We found that school district secession over the period we studied occurred in counties that were more racially diverse than the region or country. In the seven Southern counties that experienced a secession, between-district segregation for Black and White students has increased since 2000, as it has for White and Hispanic and White and Asian students. Additionally, although overall residential segregation declined during the period studied, school district boundaries accounted for an increasing share of residential segregation from 2010 to 2014. Thus, while absolute levels of residential segregation declined, existing residential segregation in impacted counties was increasingly due to residents living in different school districts. Our analysis contributes to our understanding of the erosion of mechanisms (like countywide school districts) that historically have permitted integration. More broadly, we illuminate the evolving relationship between school and residential segregation, at least in the short term, as new school district boundaries are erected and begin to acquire racialized meaning for both parents and home seekers (
Weiher, 1991).
Review of the Literature
We explore several multidisciplinary strands of literature as context for the contemporary phenomenon of Southern school district secession. History and law illuminate White Southern resistance to school integration, of which district secession is a past and present part. We then delve into the issue of school district boundary lines, seeking to understand how they contribute to segregation, especially as court-ordered desegregation is waning, and what is known about contemporary secession efforts in the South creating new district boundary lines.
Southern Resistance to School Integration
The term
secession has particular resonance in the American South after 11 states (including the three studied here) seceded from the Union, rather than abandoning the enslavement of African Americans. Despite the defeat of the Confederacy in the Civil War, White Southern political leaders passed laws sharply restricting access to and resources for education for Black children (
Anderson, 1988). African American teachers across the South fought against those laws, relying on their professional training to prepare African American students in the face of deeply discriminatory circumstances (
Walker, 2001). Still, political leaders across the region—virtually all White at that time—did not come close to providing equal resources of the
Plessy era’s “separate but equal” mandate (
Ashmore, 1954;
Carter, 1953). These ongoing inequalities became the basis for the 1954 U.S. Supreme Court ruling in
Brown that invalidated racially segregated schools in the South and border regions. Research since the time of
Brown continues to show improved social and academic outcomes for students in desegregated schools, including long-term benefits once they leave schools that are important for communities, as well (
Braddock & Gonzales, 2010;
R. Johnson, 2019;
Mickelson & Nkomo, 2012;
Trent, 1997).
Despite Thurgood Marshall’s prediction that Southern schools would be desegregated within 5 years of the
Brown decision, just 2% of Black students in the region attended majority-White schools 10 years later (
G. Orfield, 1969). State and local officials implemented a range of mechanisms to delay and then limit the extent of desegregation, including state pupil placement laws and the founding of private school academies; White suburban resistance to urban annexation also prevented government efforts that may have had a by-product of creating integration (
Connerly, 2005;
Patterson, 2001;
Pratt, 1992). Importantly, early post-
Brown efforts to avoid desegregation included White attempts to secede from countywide districts in the South (
Wilson, 2016). A judicial stance prioritizing equal protection under the law rather than local control prevailed, however. In
1972, the Supreme Court issued a decision in
Wright v. Council of City of Emporia that prevented a district secession in Virginia. The secession would have exacerbated school segregation by creating a disproportionately White city district exempt from desegregation efforts in the majority-Black county district and was announced 2 weeks after the county district’s desegregation order was issued. The
Emporia decision still stands (and was recently cited in a decision forbidding a secession attempt in Alabama), but broader legal and political forces have made it much easier for districts to secede today than in the past (
Frankenberg, Siegel-Hawley, & Diem, 2017;
Hannah-Jones, 2017;
Siegel-Hawley et al., 2018). These structures and decisions use rational discourse citing race-neutral reasons or structures to further racial inequality without invoking intentional racist beliefs (
Bobo, Kluegel, & Smith, 1997). This occurs in a larger context of a judiciary increasingly hostile to race-conscious remedies in a society predicated on racial discrimination as well as many more conservative state legislative bodies willing to remove existing backstops for secession or unwilling to pass new laws that would contain or oversee it (
Siegel-Hawley et al., 2018).
The Contribution of School District Boundaries to Segregation
The formation of new district boundary lines through secession matters because those lines help structure school and residential segregation (
Bischoff, 2008;
Owens, 2017). As
Erickson (2015) wrote, “The causal roots of educational inequality . . . can be found in the interactions between schools and the basic political and economic structures of the city and the metropolis” (p. 4). Whether segregation or desegregation would occur, she added, was the result of many decisions made by political leaders at all levels. In U.S. metropolitan areas, approximately two-thirds of school segregation is due to segregation between districts, and one third is due to segregation within districts (
Stroub & Richards, 2013). And for residents, school district boundaries account for under half of slowly declining residential segregation by race in metropolitan areas and for just over half of the residential segregation of school-age children (
Frey, 2014;
Owens, 2017). School district boundaries are therefore much more segregative for students in schools, on average, than for residents of all ages as well as for school-age children residing in neighborhoods.
Despite divergent impacts on school and residential segregation, school districts remain critical organizational units for households with and without children. More than 40 years ago, desegregation scholar
Gary Orfield (1978) noted, “United States society [has] . . . an increasing tendency for political boundaries to become racial boundaries” (p. 381). School district boundary lines are one such critical political boundary. Home seekers make residential choices with school considerations in mind (Kane, Staiger, & Riegg,
2005;
Lareau & Goyette, 2014). In an analysis of non-Southern metropolitan areas, suburban house prices increased in metros where central city districts came under a desegregation order (
Boustan, 2012; see also
O. Johnson, 2017). This means households without children are also considering the housing–school link, because increased property values are linked to neighborhoods offering access to highly-sought-after schools (
Kane et al., 2005). We might expect housing–school trends to diverge, however, in places with higher concentrations of charter schools because of the nongeographical nature of such schools (e.g.,
Pearman & Swain, 2017).
In areas with fewer political boundaries encompassing city and suburban areas, however, when coupled with the implementation of a desegregation plan, prior research shows sharper housing segregation declines than in areas with boundaries dividing suburbia from central cities (
Frankenberg, 2005;
Pearce, 1980;
G. Orfield, 2001;
M. Orfield, 2015;
Siegel-Hawley, 2016). Fewer political boundaries interrupt the school–housing calculus for advantaged families, opening the real estate market across a wide swath of the metropolitan community. It follows that housing segregation might decline less slowly—or not at all—in counties marked by the fragmented housing market associated with school district secessions.
Most prior research has examined overall residential racial segregation, not ascertaining whether there is a changing contribution to segregation within or between districts as we do here. Based on past studies, though, we expect to see increasing between-district segregation in counties experiencing secession, although such effects might be modest at first due to factors such as the time it takes for districts to develop reputations or for families to make residential moves.
Southern Demographic Patterns and Recent Southern Secessions
A study of 350 U.S. metros over a 30-year period found that school segregation was highest in areas where families could racially sort themselves across numerous district boundaries (
Fiel, 2015). Competition for access to certain schools and school districts intensified when resources were distributed in markedly unequal ways across organizational boundaries and through school choice in the form of private or charter schools. Drawing on theories surrounding racial threat, the study also found that school segregation was higher when two major racial groups approached numerical parity; this meant the dominant group was likely to employ exclusionary tactics, like expanding school choice or policing school district boundaries, to maintain its relative advantage in regard to opportunities. More hopefully, growing multiracial diversity may alleviate feelings of intense competition activated by the presence of two focal groups.
Fiel (2015) offers growth of Latino and Asian enrollment as one explanation for gradual overall declines in segregation between most student groups. These findings seem particularly relevant for the South, a region historically characterized by a sizeable Black enrollment and highly unequal resource allocation between Black and White students because of de jure segregation. Demographic change has swiftly altered the region, however. In 2016, White students made up a minority share of the enrollment (41%), and Hispanic students (28%) surpassed Black students (24%) as the largest racial minority (
Frankenberg, Ee, Ayscue, & Orfield, 2019).
Accompanying broader research related to segregation is a small set of prior studies specifically dealing with secession. In 2017, for instance, EdBuild released a national analysis of secession attempts with an update in 2019 (
EdBuild, 2019a). The group found in 2017 that 47 U.S. school districts had successfully seceded since 2000; 10 more had seceded by 2019, with more attempted and some still in process (
EdBuild, 2019a). Secessions have deleterious fiscal and racial effects for school districts left behind. Further, sharp variations in state law and policy exist governing the ease of district secession (see also
Wilson, 2016).
A series of single-case studies (
Frankenberg et al., 2017;
Siegel-Hawley et al., 2018) examined suburban secession in several Southern metros. In the postsecession Memphis, Tennessee, area, in the first year after secession occurred, more school segregation occurred because students of different races enrolled in separate school districts rather than separate schools within the same district (
Frankenberg et al., 2017). Additional research focusing solely on Jefferson County, Alabama, found that White residents have increasingly populated seceding suburban school districts. Some municipal districts that seceded decades ago, however, have experienced racial transition and had few White students (
Frankenberg, 2009;
Frankenberg & Taylor, 2017). The secessions had residential implications—a sorting of households particularly in the aftermath of secession by district boundary lines—as well as educational implications. Moreover, had the secessions not occurred, the Jefferson County School District would today enroll a majority-White student population and an additional 20,000 more students, the latter affecting funding support. A comparative look at these two metros alongside Jefferson County, Kentucky—still a merged city–suburban countywide district—found that Jefferson County, Kentucky, reported minimal school segregation, whereas between 1960 and 2012, both Jefferson County, Alabama, and Memphis-Shelby County, Tennessee, experienced high and increasing school segregation unevenly concentrated in each area’s urban school systems (
Diem, Frankenberg, Siegel-Hawley, & Cleary, 2015).
Although these case studies illuminate important aspects of school district secession, we know little about the systemic, longitudinal impacts of secession on school and housing segregation in the South. The present study will explore the role of school district boundaries over time in all Southern counties experiencing secession. Within each county, we examine school-level segregation using schools as the unit of analysis and residential segregation using block groups as the unit of analysis. This approach allows us to understand whether and, if so, how school district fragmentation is related to increased sorting of students and residents into different school districts. We examine these interrelated issues from the year 2000 to 2015, assessing segregation during the period most associated with secession. We would expect that as school district secession occurs, more school and residential segregation in the counties studied would be related to school district boundaries. And, as expected, we find that the proportion of school segregation due to school district boundaries increased from 2000 to 2015. For example, whereas school district boundaries accounted for 60% of Black and White school segregation in 2000 in our sample of counties, by 2015 that proportion had increased to 70%. At the same time, school district boundaries may have had a delayed effect in impacted counties on residential segregation, whereby from 2010 to 2014 there was an increase in the proportion of residential segregation due to school district boundaries. Such trends will be important to monitor as district boundary lines in these counties continue to accrue meaning for home seekers, particularly households with school-age children.
Method
In this study, we use a research design that allows us to determine the unique contribution of school district boundaries to racial school and residential segregation in Southern counties experiencing secession. Decomposing Theil’s H (
Theil, 1972), an evenness measure of segregation, means that we can identify the proportion of school and residential segregation due to school district boundaries at different time points as school districts secede from county districts.
2 We compare resident trends to public school student trends to help us understand to what extent district secessions are related to both residential and school segregation. We also explore how school district boundaries segregate populations and students depending on race (i.e., if school district boundaries are more segregative for Black and White residents than for Hispanic and White residents).
Sample
From 2000 to 2017, 47 school districts have successfully seceded from a larger school district in the United States (
EdBuild, 2019a). These secessions have affected 13 counties across the United States, seven of which are in the South. In this study, we focus on the school district secessions that have occurred in the South, including the 18 new districts identified by EdBuild that have formed during this time period.
3 We focus on the South because of the unique role countywide school systems have played in the region in terms of school desegregation and because secession can be seen as a continuation of Southern strategies used to avoid integration.
4 Although many of these districts were once under court-ordered desegregation plans, today most have been declared unitary.
5 We examine racial segregation, both school level and residential level, in the seven Southern counties where school district secessions have occurred since 2000: Jefferson, Marshall, Mobile, Montgomery, and Shelby Counties in Alabama; East Baton Rouge Parish, Louisiana; and Shelby County, Tennessee. In three counties, secessions did not occur until after 2010. Thus, for the first decade of our analysis, we expect relatively lower changes in between-district segregation.
To conduct our analysis, we measure the residential segregation that occurs within school districts, as compared to the residential segregation that occurs between districts, in the seven counties. Similarly, we measure the segregation of students within school districts, and between school districts, to determine changes over time as school districts secede. We select school districts that are geographically within each county that experienced a secession (see
Table 1 for frequency of school districts at each time point).
6In the seven Southern counties impacted by secession, the aggregate residential population became majority non-White between 2000 and 2014. In the same counties, the public student enrollment was already majority non-White in 2000 and became increasingly so over time. White students made up only 32% of enrolled students in 2015, down from 42% in 2000. These counties had a disproportionately more diverse enrollment than the region: The entire South region had 54% White students in 2000 and 43% in 2014. A sharp increase in the share of Hispanic students occurred in several of the counties. For the seven counties experiencing secession, the enrolled public school student and resident population were disproportionately non-White in comparison to the entire region.
By 2015, non-geographically-based schooling options arose in the two non-Alabama counties. In Tennessee, the state-run Achievement School District (ASD) operated 27 schools comprising 6.3% of the enrollment (
Table A1 in the
appendix). In 2010 there were two charter local education agencies (LEAs) in East Baton Rouge Parish, which had grown to 16 by 2015. We treat each of these charter LEAs and ASD as separate districts. Finally, in 2015, the two central-city districts, Shelby County and East Baton Rouge, contained a handful of charter schools along with traditional schools, which we consider to be part of the district like other noncharter schools. The first charter school in Alabama opened after 2015 and was not included in this study.
Data
The data in this study are drawn from several sources, including census demographic data at the block group level, Common Core of Data (CCD) demographic data at the school level, and TIGER/Line geographic data at the block group, school district, and county levels. Bringing together these data sources allows us to examine population and student patterns simultaneously and to study populations in relevant educational geographies.
Census
We measure racial residential segregation using the four largest racial groups in the United States: White, Black, Hispanic, and Asian residents. To conduct the residential portion of this analysis, measuring the extent to which residents are sorted unevenly
between school districts and unevenly among neighborhoods
within school districts, it is necessary to utilize census units within school districts. We use block groups for this purpose because they are smaller than tracts and yield a more precise estimate of segregation within educational geographies. We use areal interpolation with the TIGER/Line block group and school district shapefiles to estimate block group populations within school districts (
Logan, Xu, & Stults, 2014;
Saporito, Chavers, Nixon, & McQuiddy, 2007) because block groups (and other census geographies) do not nest perfectly within school districts. Areal interpolation is a useful technique for education researchers that utilize census data because it makes it possible to estimate populations within school boundaries and, in this study, allows for the measurement of residential segregation within school district boundaries. We created block group estimates from 2000, 2010, and 2014 for each school district. Often, racial residential segregation is measured using tracts, which are larger administrative units than block groups. When measuring segregation with smaller administrative units, like block groups, the result will usually be higher segregation because of the nature of the unit of measurement. It is important to keep this in mind when interpreting the findings on racial residential segregation. In our residential analysis, the overall county segregation and within-district component will be relatively higher when using block groups as compared to using tracts. Therefore, considering changes over time in segregation at the residential level will be most useful, rather than considering absolute levels of segregation. Additionally, comparisons between school and residential segregation must also be made in the context of the differences in composition between the student population and the residential population. Consistently, White residents are a higher percentage of the county population than are White students of the county’s public school student enrollment.
CCD
To study school-level segregation, we measure segregation in schools among the four largest racial groups during the 1999–2000, 2009–2010, and 2014–2015 school years. We include the same school districts in the school-level analysis as are in the residential analysis to allow for comparison of patterns at the school level and residential level. Only regular public schools (e.g., not including vocational, special education, or alternative schools) are included as we explore the extent to which students are segregated between and within school districts in the counties where school districts have seceded since 2000. We also include charter schools in Tennessee and Louisiana if they are not vocational, special education, or alternative schools.
Analysis
Using Theil’s H (
Theil, 1972), we report on the magnitude of segregation at different geographic scales from 2000 to 2014–2015. These scales include segregation in the entire county, segregation between school districts, and segregation within school districts. For each, segregation is measured for both the residential population and public school enrollment. Theil’s H is an evenness measure of segregation that reports on how much less diverse a subunit is as compared to the area of study (for example, how much less diverse, on average, schools are as compared to the entire school district). Ranging in value from 0 to 1, a low H value indicates students/residents are evenly sorted among subunits, whereas a high H value indicates that students/residents are unevenly sorted among subunits. We examine multigroup segregation, which allows us to evaluate the segregation of all groups simultaneously, as well as racial dyads. H has the advantage of being decomposable across geographic units (
Reardon & Firebaugh, 2002), which makes it possible to determine the unique contribution of a subunit, in this case, school districts, to the overall segregation of counties. For example, an H value of .25 at the school district level means that the school district is 25% less diverse than the county. At the population level, we decompose Theil’s H to determine the contribution of school districts to county residential segregation. Similarly, we decompose H at the school level to understand the contribution of school districts to county school segregation (relative to within-district segregation). We are particularly interested in how county H values and their components (e.g., school districts) have changed over time as school districts have seceded.
Other segregation measures, like exposure, indicate the interracial contact that students or residents might have in a unit of analysis. One weakness of using an evenness measure of segregation as we do here is that it can fail to account for the exposure dimension of segregation (
G. Orfield, Siegel-Hawley & Kucsera, 2014). If a school district is 85% one race, and if all the schools in that district are close to 85% that race, then the school district can be described as experiencing low segregation. However, in this scenario, there is little exposure to students of other races. When measuring school segregation using an evenness measure, school segregation is often declining, but when measured using an exposure measure, school segregation is often increasing (
G. Orfield et al., 2014). Segregation often declines when using an evenness measure because the diversity of schools is, on average, increasing. However, at the same time, White, Black, and Hispanic students tend to be increasingly isolated in schools. The changing racial composition of the counties under study (see
Table 1) demonstrates that even if students are distributed more evenly among schools, students themselves may increasingly be racially isolated. This is related to the increasingly non-White composition of the student population. Although not described below, we find some evidence of such trends in exposure in some of the counties studied here.
7Discussion
In a region known for the desegregative influence of its countywide school districts, particularly for Black and White students, school district secession in seven counties in the South has erected new boundaries that largely prohibit student transfer across them, and in many places, the newly formed districts, by and large, were more racially homogeneous than the larger county districts that housed them in 2000. Such new boundaries contribute to an increasing share of overall county-level segregation by 2015. Furthermore, secession continues apace beyond the time period we examined. With the passage of time, initial effects, particularly for residential segregation, may grow stronger.
9 In these seven counties, where a combined 18 new school districts—as well as charter schools in states that authorized them—formed from 2000 to 2015, increased residential integration
and racial diversity in the counties may activate perceptions of racial threat as Black student enrollment approached parity or surpassed that of White student enrollment (
Fiel, 2015). This, in turn, can fuel the perceived stakes around securing relative schooling advantage through secession efforts (
Stout v. Jefferson County Board of Education,
2018). Although residential segregation patterns suggest there may have been a delayed effect, in the counties with the most extensive patterns of secession, we saw that boundaries were beginning to be racialized boundaries for residents as well as for students.
Indeed, the public school enrollment in the counties experiencing secession was increasingly non-White, whereas the residential population remained about 50% White. This demographic divergence from the rest of the region and country may be driving some of the motivation for secession. Our county-level analysis shows that secession has occurred in large Southern school systems with substantially lower shares of White students (roughly 33%) than the South as a whole (43%), suggesting that racial threat and competition may be at work (
Fiel, 2015). Through the creation of new boundary lines, secession becomes a political mechanism for disproportionately White communities to maintain relative advantage in terms of student composition and, likely, financial resources, given the funding gaps between predominantly minority and predominantly White districts (
EdBuild, 2019b). In the recent Gardendale, Alabama, secession attempt, a member of the advisory board for the secession wrote, “A look around at our community sporting events, our churches are great snapshots of our community. A look into our schools, and you’ll see something totally different” (
Stout v. Jefferson County Board of Education,
2018, p. 11). The something “totally different” was the racial diversity of public schools, a result of court-ordered school desegregation efforts in what remains of the countywide district Jefferson County that was 43% White and 47% Black in 2015. The differences between the community and the schools was also cited by residents as a reason to form their own separate district to keep students of color out of their community’s schools. Although the federal courts prohibited the Gardendale secession attempt, similar forces have successfully created new boundary lines in other places without ongoing court orders.
Our analysis shows that a relatively higher percentage of school segregation in these seven Southern counties now occurs because students are enrolled in separate school districts, not just separate schools. School district secession has meant that segregation between Black and White students, and between Hispanic and White students, deepens between school districts. By 2015, the proportion of school segregation due to school district boundaries was approaching three quarters for Black and White students. And for Hispanic and White students, whereas in 2000 school district boundaries accounted for about a third of school segregation, by 2015 that proportion had increased to two thirds.
This systematic examination of 15 years of secession in the South also provides preliminary evidence that school district secession is eroding what has historically been one of the cornerstones of school desegregation in the South: the one-county, one-school-system jurisdiction. In counties where secession has eroded the countywide advantage for school integration (i.e., Jefferson County and Marshall County), it has done so in places where multiple significant secessions have occurred over time, meaning that there is no longer one school district that enrolls most students in the county. District secession is associated with increasing segregation of students across district lines, particularly for Black and White students, and Hispanic and White students.
County-level results point to a nuanced relationship between school and housing segregation in communities experiencing secession. Counties experiencing secession over a longer period and containing several sizeable school districts experienced higher segregation between school districts for residents than counties undergoing more recent secessions impacting smaller numbers of residents. For example, in Jefferson County, Alabama, school district boundaries in 2014 contributed to approximately 40% of the racial
residential segregation in the county—which was quite high. This underscores the fact that in a county with a long history of school district secession, school district boundaries contribute substantially to the residential segregation of the total population, including those without children in the public schools. Neighborhood segregation is often cited as the root cause of school segregation (see
Rothstein, 2017), but the divergence here in school and residential segregation patterns demonstrates that the relationship is more complex and dynamic. In the counties impacted by secession, on average, the construction of new school district boundaries was associated with a rise in their segregative role for students, but not for residents, at least in the short term. Our findings are an important foundation for future research with a longer time horizon to assess changes in residential sorting associated with more recent district secessions. It remains important to monitor the residential as well as school trends in the long term as school composition becomes increasingly shaped by the new boundaries, which then may become an important amenity in marketing homes in the counties with more recently formed districts. It is also unclear how the growth of charter schools in the region might emerge as a complementary segregating mechanism from countywide districts and whether that has a different longer-term effect on residential segregation.
Ultimately, the trends documented here point to secession as a new form of resisting desegregation amid the growing diversity of the South’s public schools. Secession has weakened the potential for greater school integration across the South’s broadly defined communities, fracturing White and Black and White and Hispanic students into separate school systems. Given the obstacles to comprehensive cross-district integration policies, secession makes it ever more difficult to bring them back together. Although the link between school and housing segregation in Southern communities impacted by secession is less clear-cut, trends in places with long-standing secession experience suggest that their neighborhoods will become more residentially divided along with their schools. The array of negative consequences outlined here should give states and communities substantial pause as secession efforts accelerate. A framework for examining the damages of proposed secessions is sorely needed—and oversight related to the impact of existing secessions past due.
