State of the Science of Structural Stigma and LGBTQ+ Health: Meta-Analytic Evidence, Research Gaps, and Future Directions.

While public health practitioners and scholars have long theorized that structural forms of stigma shape the health of disadvantaged groups, they have frequently bemoaned the lack of research on this topic. A unique opportunity to address this lacuna occurred in the past two decades, with the advent of dramatic changes in laws, social attitudes, and other structural manifestations of stigma surrounding LGBTQ+ individuals. In a review of this literature, we conducted a meta-analysis of LGBTQ+ structural stigma and health, finding an effect size comparable to several other well-established macrolevel risk factors for poor health (e.g., income inequality, racial residential segregation, neighborhood socioeconomic status). In addition, we enumerated a range of established methodological strategies that studies have used to strengthen inferences; these strategies include documenting result specificity (i.e., structural stigma is unrelated to the health of cisgender heterosexuals), addressing alternative explanations (e.g., social selection), and triangulating evidence across multiple methods, measures, and health outcomes. We offer suggestions for future research to advance this rapidly expanding field, including identifying sources of unexplained heterogeneity in the structural stigma-health association. Finally, we discuss implications for other marginalized groups and for public health interventions and policies to reduce LGBTQ+ health disparities.

Finding a Home during the Affordable Housing Crisis: How Social Ties Shape Renters’ Housing-Search Outcomes

Housing searches play a central role in the reproduction of racial inequality in U.S. cities. Past research finds that movers’ social ties influence residential segregation, as renters receive information about homes located near friends and family. Fewer studies examine how renters’ social ties also provide instrumental assistance during moves, or how this aid unequally shapes moving outcomes. In the present study, I show how 69 low-income, Latina/o and non-Hispanic white renters rely on their friends, family, and acquaintances to navigate moves in Los Angeles, a highly unaffordable rental market. Both groups mobilize their ties for instrumental assistance, but the resources available through renters’ ties contribute to diverging search outcomes. Low-income Latina/o renters’ ties, who also struggled to make ends meet, provided what I call constrained support—referrals to open units, loans to cover moving costs, and informal rental opportunities. This assistance channeled movers to specific apartments and left them negotiating informal, doubled-up homes and new debt. In contrast, low-income white renters leveraged comparatively affluent ties to cosign leases, provide financial gifts, and strengthen applications across buildings—what I refer to as flexible assistance. This aid helped low-income white movers secure housing advantages, while avoiding short-term reciprocal obligations to friends and family. These findings advance research on residential mobility and social support, and they show how network resource inequalities contribute to racial stratification in rental markets.

The significance of culture for social sustainability – a discussion of cultural security and insecurity in neighbourhoods

ABSTRACT Creating a socially sustainable city will often encompass strategies to ensure that the different communities are “cohesive” and that the many neighbourhoods are diverse to prevent residential segregation. However, the literature on diverse communities and urban diversity has detailed processes of avoidance, exclusion, and friction as well as addressed the coping mechanisms that some residents develop. In this paper, we analyse ethnographic data from Oslo, Norway, with the aim to contribute to the research on neighbourhood social sustainability and residential preferences. It is claimed that to understand such preferences, the concepts of cultural security and cultural insecurity are useful. People’s interest in “culture” may pose a challenge to policy makers’ visions for socially sustainable urban development.

Multidimensional structural racism and estimated cancer risk from traffic-related air pollution.

Traffic-related air pollutants have been associated with a variety of adverse human health impacts, including cancers. In the United States, numerous studies have documented racial inequities in neighborhood exposures to traffic-related air pollution. Emerging evidence suggests that structural racism may influence neighborhood exposures to air pollutants. However, existing research has largely focused on residential racial segregation, one indicator of structural racism. This study developed a multidimensional measure of structural racism to examine the relationship between structural racism and estimated cancer risk from air pollutants in Georgia. Carcinogenic air toxics data were obtained from the US Environmental Protection Agency's 2019 Air Toxics Screening Assessment and sociodemographic data from the American Community Survey. Guided by stakeholder input, county-level data on residential segregation, education, employment, incarceration, economic status, political participation, and homeownership were used to create a multidimensional county-level structural racism index. Relative risks (RRs) were estimated for associations between structural racism and elevated (top 10% in Georgia) estimated cancer risk from air toxics. Multilevel analyses revealed a significant association between multidimensional structural racism and exposure to carcinogenic traffic-related air pollutants. Neighborhoods in the highest quartile of structural racism exhibited an elevated cancer risk from traffic-related air pollutants (RR,7.84; 95% CI,5.11-12.05) compared to neighborhoods with lower levels of structural racism. Multidimensional structural racism was associated with estimated cancer risk from traffic-related air pollution in Georgia. Findings can inform future studies and policy interventions that address racial inequalities in exposure to traffic-related air pollution.

Impact of Contemporary Redlining on Healthcare Disparities Among Patients with Gastrointestinal Cancer: A Mediation Analysis.

Historically, housing policies have perpetuated the marginalization and economic disinvestment of redlined neighborhoods. Residential segregation persists nowadays in the form of contemporary redlining, promoting healthcare disparities. The current study sought to assess the effect of redlining on oncological outcomes of patients with gastrointestinal cancer and identify mediators of the association. Patients with colorectal or hepatobiliary cancer were identified from the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database (2007-2019). The contemporary redlining index, a measure of mortgage lending bias, was assessed relative to disease stage at diagnosis, receipt of appropriate treatment, textbook outcome, and mortality. Mediation analysis was used to identify socioeconomic, structural, and clinical mediating factors. Among 94,988 patients, 32.2% resided in high (n = 23,872) and highest (n = 6,791) redlining census tracts compared with 46.2% in neutral and 21.6% in low redlining tracts. The proportion of Black, Hispanic, and White patients experiencing high and highest redlining was 65.9%, 41.6%, and 27.9%, respectively. Highest redlining was associated with 18.2% higher odds of advanced disease at diagnosis, greater odds of not undergoing surgery for localized disease (adjustedodds ratio [aOR] 1.363, 95% confidence interval [CI] 1.219-1.524) or not receivingchemotherapy for advanced disease (aOR 1.385, 95% CI 1.216-1.577), and 26.7% lower odds of textbook outcome achievement. Mediation analysis for appropriate treatment quantified the proportion of the association driven by socioeconomic status, racial/ethnic minority status, racial/economic segregation, primary care shortage, and housing/transportation. Contemporary redlining contributed both directly, and via downstream factors, to disparities in oncological care and outcomes of patients with gastrointestinal cancer.

Effects of the Hukou system on the geographies of young people in contemporary urban China

ABSTRACT The Chinese institution for population registration is called the hukou system. It divides residents into local and non-local hukou holders concerning geographical mobility. Within Chinese society, young people often move away from their birthplace and subsequently become non-local hukou holders in the destinations. The hukou system has become a barrier to the access of young people to urban rights, placing them in a peripheral position in society. To understand the often-overlooked geographies of young people in China, the article examines how the hukou system undermines young people’s right to the city. Subsequently, the invisible politics of young people in China is discussed, based on a scoping review that approaches the issue through three themes: young people’s tactics in their mobilities; housing inequality and residential segregation; and young people’s aspirations for the future. Combining authoritarianism and neoliberalism, the hukou system controls the distribution of city rights, and thus regulates the flows of young people. Such regulation constitutes a transitional regime that shapes the life trajectories of Chinese youths. Therefore, the article recommends hearing the voices of Chinese young people in the field of Children’s Geographies, and thus enabling their voices to influence future reforms of hukou policies.

What has Contributed to Green Space Inequities in U.S. Cities? A Narrative Review

Much research has documented green space inequities, but no review has examined their determinants holistically. To address this gap, we conduct a narrative review to synthesize the historical and recent mechanisms contributing to green space inequities in U.S. cities. We identify 77 publications covering this topic and find that two complementary macro-mechanisms shape green space inequities: residential segregation and unequal green space investments. Historical mechanisms include racial residential segregation, redlining, and postwar suburbanization. More recent mechanisms include nonprofits’ involvement in green space provision, green gentrification, and contemporary plans. Moving toward green space equity requires addressing both historical and current mechanisms.

Residential and experienced social segregation: the roles of different transport modes, metro extensions, and longitudinal changes in Hong Kong

Social segregation is a challenge intensified by rapid urbanisation. Using mobility data, researchers have widened the scope of analysis from static residential segregation patterns to experienced segregation in activity space. Despite such progress, we have yet to decipher how social segregation evolves with the urban development process. The different roles of transport modes, major transport infrastructure expansion, and longitudinal changes over decades are rarely captured. This study utilises three Hong Kong Travel Characteristics Surveys data from 1992 to 2011 to analyse the city’s social mixing changes. Detailed mobility and socio-demographic data of 101,385 (2011), 92,520 (2002) and 77,271 (1992) individuals were included. We found that the unequal experience of social segregation among different social demographic groups has persisted across the two decades. Nevertheless, public transit has a significant effect in increasing social mixing, thereby moderating the experienced social segregation. The roles of buses and the metro system are particularly noteworthy. Nonetheless, we found a selection bias of new metro stations in areas of high social mixing already. Over time, the metro expansion plays a paradoxical role. On one hand, the metro stations’ immediate catchment areas have seen a decreased low-income population. On the other hand, the increased number of metro trips allows people to have a more diverse experience.

A matter of measurement? Segregation and all-cause mortality in Sweden’s three metropolitan regions

Abstract Background Residential segregation can be operationalized and measured in many ways, along distinct dimensions. There are multiple mechanisms through which segregation and health mutually affect each other. Consequently, contextual health effects of segregation may vary depending on how segregation is measured. Methods We used longitudinal Swedish register data to compare associations between local measures of residential segregation (migrant density, migrant isolation, and the mutual information index) and all-cause mortality among the adult migrant and native-born populations in Sweden’s three largest metropolitan regions between 2004-2016. Results Among migrants, modest positive mortality gradients were observed across measures of migrant density and isolation, where a higher level of segregation was associated with higher risks of all-cause mortality (Q5 RR ranged from 1.08-1.20 across cities and measures). However, these effects were largely attenuated by individual-level socioeconomic factors, and reversed when further controlling for neighborhood economic deprivation (Q5 RR ranged from 0.74-0.87). Among the native-born, a positive gradient for mortality was found (Q5 RR ranged from 1.31-1.45), although this was reduced when accounting for neighborhood deprivation (Q5 RR ranged from 1.01 -1.11). For both migrants and the native-born, the mutual information index showed no clear association with mortality, although a mortality advantage is observed for migrants in the most segregated areas after individual and neighborhood level adjustments (Q5 RR ranged from 0.73-0.86). Conclusions Our findings show that the manner in which residential segregation is conceptualized and operationalized alters associations with health. However, individual and other contextual level confounders are important determinants which influences the patterns. Much of the negative health effects of residential segregation can be perceived through the lack of economic opportunities. Key messages • Associations between segregation and all-cause mortality depends on how segregation is conceptualized and measured. • The mortality disadvantage observed in local areas with high migrant density may be attributed to the lack of economic opportunities in the neighborhood.

Exploring Urban Socio-Spatial Disparities in Liverpool, Manchester, and Newcastle upon Tyne Metropolitan Areas

In recent decades, rising social disparities in European cities have structured new forms of urban inequalities. Employing an innovative analysis approach based on statistical, geographical, and spatial methods, this paper aims to explore the social geography of population groups in Liverpool, Manchester, and Newcastle upon Tyne by examining how the spatial distribution of socio-economic groups intersects with urban settlements of the resident foreign population. The study addresses methodological challenges in segregation measurement while shedding light on existing spatial patterns of vulnerable groups and emerging trajectories of residential segregation at the metropolitan scale, utilising the most recent UK Census data.

Barriers and Boundaries: How Residents Make Meaning of Segregating Built Environments

Built environments have structured urban space in racist and classist ways, contributing to residential segregation and related inequalities. Previous research has examined how perceivable built environment features become symbolic boundaries that structure both socio-spatial division and meaning-making, but little research has examined how physical barriers—features that carry symbolic meaning and limit connectivity between nearby areas—may promote both symbolic “othering” and inhibit contact between residents on either side. Drawing on ethnographic fieldwork, we examine how residents interpret and experience physical barriers and symbolic boundaries in race-, income-, and race-and-income distinct areas in Houston, Texas. We describe three typologies of barriers/boundaries (unremarkable, intrusive, and hyper-salient), demonstrating how the same barrier or boundary can have different meanings for people on either side. For physical barriers, these meanings were often mediated by residents’ actions. Our findings extend theorization of how the built environment shapes interpretations and experiences of segregation, and vice versa.

The implications of digital school quality information for neighbourhood and school segregation: Evidence from a natural experiment in Los Angeles

A digital information explosion has transformed cities’ residential and educational markets in ways that are still being uncovered. Although urban stratification scholars have increasingly scrutinised whether emerging digital platforms disrupt or reproduce longstanding segregation patterns, direct links between one theoretically important form of digital information – school quality data – and neighbourhood and school segregation are rarely drawn. To clarify these dynamics, we leverage an exogenous digital information shock, in which the Los Angeles Times’ website revealed measures of a particularly important school quality proxy – schools’ value-added effectiveness – for nearly all elementary schools in the Los Angeles Unified School District. Results suggest that although the information shock had no detectable effects on residential sorting or neighbourhood racial segregation, it did exert modest effects on school sorting – particularly for Latino and Asian students – albeit not in ways that materially diminished school racial segregation because the racial compositions of high- and low-value-added schools were broadly similar both before and after the information shock. We conclude that the urban stratification implications of digital information may be more nuanced than often appreciated, with effects operating through mechanisms beyond residential segregation and reflecting racial heterogeneity in constraints and preferences vis-à-vis specific types of information.

Underlying Dimensions of Racial Residential Segregation and Police-Caused Homicide of Blacks: A Cross-Sectional Analysis of Core Based Statistical Areas

This work builds upon previous research to assess the associations between underlying dimensions of racial residential segregation and police-caused homicide of Black civilians. Previous scholars have observed that much of the existing work on residential segregation and police-caused homicide has used one measure of segregation, most commonly the dissimilarity index, although recent work has expanded the focus to include multiple indicators of segregation. Our research extends this research by computing multiple measures of racial residential segregation for a sample of U.S. Core Based Statistical Areas in 2010 and factor analyzing them to identify underlying dimensions. Measures of the resulting dimensions are merged with the Mapping Police Violence data on police-caused homicide. The analyses reaffirm and extend previous conclusions about the importance of spatial relationships within residential locations for understanding contemporary police-caused homicide, while raising questions about the underlying theoretical mechanisms.

Association of Racial Residential Segregation and Other Social Determinants of Health with HIV Late Presentation.

Understanding social determinants of HIV late presentation with advanced disease (LPWA) beyond individual-level factors could help decrease LPWA and improve population-level HIV outcomes. This study aimed to examine county-level social determinants of health (SDOH) with HIV late presentation. We aggregated datasets for analysis by linking statewide HIV diagnosis data from the South Carolina (SC) Enhanced HIV/AIDS Reporting System and multiple social contextual datasets (e.g., the American Community Survey). All adult (18 years and older) people with HIV diagnosed from 2014 to 2019 in SC were included. Linear mixed models with forward selection were employed to explore the association of county-level SDOH with the county-level three-year moving average percentage of LPWA and average delay time from HIV infection to diagnosis. Around 30% of new HIV diagnoses were LPWA in SC, and the mean delay time for people with LPWA was approximately 13 years. Counties with more racial residential segregation had longer average delay time (Adjusted beta = 5.079, 95% CI: 0.268 ~ 9.889). Regarding other SDOH, the increased percentage of LPWA was associated with fewer Ryan White centers per 100,000 population (Adjusted beta = -0.006, 95% CI: -0.011~-0.001) and higher percentages of the population with less than a high school education (Adjusted beta = 0.008, 95% CI: 0 ~ 0.015). Reducing county-level disparities in LPWA requires multifaceted interventions addressing multiple dimensions of SDOH. Targeted interventions are needed for counties with more Black residential segregation, fewer Ryan White centers, and higher percentages of less than high school education.

Racial Residential Segregation and Mental Health During Pregnancy

Research suggests the social, physical, and socioeconomic contexts of residing in segregated neighborhoods may negatively affect mental health. To assess the association between racial residential segregation and prenatal mental health among Asian, Black, Hispanic, and White individuals. This population-based cross-sectional study was conducted in Kaiser Permanente Northern California (KPNC), an integrated health care delivery system. Participants included self-identified Asian, Black, Hispanic, and White pregnant individuals who attended at least 1 prenatal care visit at KPNC between January 1, 2014, and December 31, 2019. Data were analyzed from January 14, 2023, to August 15, 2024. Racial residential segregation, defined by the local Getis-Ord Gi* statistic, was calculated in each racial and ethnic group and categorized as low (<0), medium (0-1.96), or high (>1.96). A positive Gi* statistic indicates overrepresentation (greater clustering or segregation) of the racial and ethnic group in an index census tract and neighboring tracts compared with the larger surrounding geographic area. Prenatal depression and anxiety defined by diagnoses codes documented in the electronic health record between the first day of the last menstrual period and the day prior to birth. Among the 201 115 participants included in the analysis (mean [SD] age, 30.8 [5.3] years; 26.8% Asian, 6.6% Black, 28.0% Hispanic, and 38.6% White), prenatal depression and anxiety were highest in Black individuals (18.3% and 18.4%, respectively), followed by White (16.0% and 18.2%, respectively), Hispanic (13.0% and 14.4%, respectively), and Asian (5.7% and 6.4%, respectively) individuals. Asian (40.8% vs 31.1%) and Black (43.3% vs 22.6%) individuals were more likely to live in neighborhoods with high vs low segregation, while Hispanic individuals were equally likely (34.3% vs 34.7%). High compared with low segregation was associated with greater odds of prenatal depression (adjusted odds ratio [AOR], 1.25 [95% CI, 1.10-1.42]) and anxiety (AOR, 1.14 [95% CI, 1.00-1.29]) among Black individuals. High segregation was associated with lower odds of prenatal depression among Asian (AOR, 0.75 [95% CI, 0.69-0.82]), Hispanic (AOR, 0.88 [95% CI, 0.82-0.94]), and White (AOR, 0.91 [95% CI, 0.86-0.96]) individuals. Similar associations were found for anxiety among Asian (AOR, 0.80 [95% CI, 0.73-0.87]) and Hispanic (AOR, 0.88 [95% CI, 0.82-0.93]) but not White (AOR, 0.95 [95% CI, 0.90-1.00]) individuals. In this cross-sectional study, racial and ethnic residential segregation was associated with worse prenatal mental health for Black individuals but better mental health for Asian, Hispanic, and White individuals. Policies reducing segregation and its impact may improve mental health outcomes in pregnant Black individuals.

Communal Intimacies

The reproduction of the American home hinges on a clear public/private distinction, wherein the private sphere is traditionally viewed as domestic — a space for interpersonal care and social reproduction, distinct from the abstract political culture of the public. Due to American legal and cultural norms maintaining this division, the mainstream LGBTQ rights movement has privileged privacy as a portal of legitimation, often to the detriment of poor, queer people of color without access to private property. Amid residential segregation, mass incarceration, and welfare reform, queer people of color must reshape and repurpose both public and commercial space to collectively affirm their erotic desires and care for each other through “communal intimacies,” the spatial-kinship practices that decouple care from the domestic, create a pathway for the transfer of libidinal pleasures, and act as a foundation for envisioning and enacting a world of belonging and transformation despite gentrification. Through cultural analysis of John Leguizamo's performance of the “Manny the Fanny” character from his 1991 show Mambo Mouth and Sean Baker's 2015 film Tangerine, this article illustrates novel forms of homemaking that blur the boundaries denoting the public/private spatial divide inherent in neoliberal property regimes.

Ride-hailing technology mitigates effects of driver racial discrimination, but effects of residential segregation persist

We assess racial disparities in the service quality of app-based ride-hailing services, like Uber and Lyft, by simulating their operations in the city of Chicago using empirical data. To generate driver cancellation rate disparities consistent with controlled experiments (up to twice as large for Black riders as for White riders), we estimate that more than 3% of drivers discriminate by race. We find that the capabilities of ride-hailing technology to rapidly rematch after a cancellation and prioritize long-waiting customers heavily mitigates the effects of driver discrimination on rider wait times, reducing average discrimination-induced disparities to less than 1 min-an order of magnitude less than traditional taxis. However, our results suggest that even in the absence of direct driver discrimination, Black riders in Chicago wait about 50% longer, on average, than White riders because of historically informed geographic residential patterns. We estimate that if Black riders in the city had the same wait times as White riders, the collective travel time saved would be worth $4.2 million to $7.0 million per year.
