Neighborhood Conditions and Social Network Turnover among Older Adults

Increasing research highlights heterogeneity in patterns of social network change, with growing evidence that these patterns are shaped in part by social structure. The role of social and structural neighborhood conditions in the addition and loss of kin and non-kin network members, however, has not been fully considered. In this paper, we argue that the residential neighborhood context can either facilitate or prevent the turnover of core network relationships in later life - a period of the life course characterized by heightened reliance on network ties and vulnerability to neighborhood conditions. Using longitudinal data from the National Social Life, Health, and Aging Project linked with data from the American Community Survey, we find that higher levels of neighborhood concentrated disadvantage are associated with the loss of older adults' kin and non-kin network members over time. Higher levels of perceived neighborhood social interaction, however, are associated with higher rates of adding non-kin network members and lower rates of adding kin network members over time. We suggest that neighborhood conditions, including older adults' perceptions of neighborhood social life, represent an underexplored influence on kin and non-kin social network dynamics, which could have implications for access to social resources later in the life course.

Lessons Learned from a Citywide Abandoned Housing Experiment

Problem research strategy and findings

The negative impact of vacant and abandoned housing in city neighborhoods is extreme, affecting health and quality of life, promoting violence, and leading to further abandonment. One approach to addressing abandoned housing is to intervene with low-cost interventions that provide a visual sense of ownership. We tested whether a low-cost remediation of abandoned and vacant houses or a trash cleanup intervention would make a noticeable difference in the levels of nearby disrepair, disorder, and public safety. The abandoned housing remediation and trash cleanup interventions were a test of compliance with municipal ordinances. We used an experimental design to test the causal effects of the ordinances, and because the scale of abandonment was too large to provide treatment to all abandoned houses in the city. We used systematic social observation methods to rate changes in disrepair, disorder, and litter at housing sites and on the city blocks they were located, and police reported data on gun violence and illegal substance uses. Our experimental design allowed us to see if observed disrepair, disorder, and public safety improved after working windows and doors were installed on abandoned houses compared with a trash cleanup around properties or a no-intervention control condition. Our results showed significant changes in observed disrepair, disorder, and gun violence and illustrate the benefits of experimental evaluations of place-based changes to the built environment.

Takeaway for practice

Improving compliance with ordinances to remediate abandoned housing can make a noticeable difference in disrepair in neighborhoods and contribute improved public safety. We illustrate how planners can use field experiments in partnership with city agencies, nonprofit community groups, and local universities to discover novel approaches to advance place-based changes to the built environment that can help economically disadvantaged communities abate problems of physical disorder.

Pockets of Peace: A mixed methods, exploratory study of neighborhoods resilient to juvenile violence

Social science research has focused on hot spots of adolescent violence in marginalized urban neighborhoods for nearly a century. In contrast, in this study, we explore under-resourced urban areas that do not experience high rates of adolescent violence: "pockets of peace." We use a mixed-method approach to identify the sociodemographic, geographic, and criminological commonalities and differences between pockets of peace and other areas of concentrated disadvantage dealing with high rates of adolescent violence in Indianapolis, IN. More than one out of every ten of Indianapolis' areas of concentrated disadvantage meet the criteria to be labeled "pockets of peace." Quantitative data indicate that these areas have fewer prosocial institutions and experience lower homeownership rates than comparison under-resourced areas, and qualitative data point toward rental stability and residential longevity as potentially salient social factors within these contexts. As an alternative to using statistics to control for the context of structural disadvantage, studying pockets of peace and other "cold-spots" of adolescent violence presents an opportunity to understand community-level resilience within the real, lived context of structural disadvantage.

Communities, Streets, and People: A Multi-level Study of the Correlates of Victimization

The current study adds the context of the immediate microgeographic environment (measured as the street segment) to the study of individual victimization. Using residential survey and physical observation data collected on 449 street segments nested within 53 communities in Baltimore, MD, we employ multilevel logistic regression models to examine how individual risky lifestyles, the microgeographic context of the street, and community level measures influence self-reported property and violent crime victimization. Results confirm prior studies that show that risky lifestyles play a key role in understanding both property and violent crime victimization, and community indicators of disadvantage play a role in explaining violent crime victimization. At the same time, our models show that the street segment (micro-geographic) level adds significant explanation to our understanding of victimization, suggesting that three level models should be used in explaining individual victimization. The impact of the street segment is particularly salient for property crime.

Providing a safer passage: Perceptions about a neighborhood intervention program for disadvantaged youth

"Safe Passage" is an after-school intervention program for disadvantaged youth in a medium-sized city in southern California. Led by local law enforcement, as well as the city's recreation and park department, the program's goal is to combine community policing with after-school care and tutoring to support children living in a large apartment complex with the highest rates of gang membership and crime in the city. This is an exploratory study that examines the perspectives of various stakeholders in the intervention program, including the community members, the local police, and Safe Passage staff members. Survey data from the community residents, program staff and law enforcement were collected. Findings indicate that there was some consensus across the various subpopulations on the challenges that have had the largest negative influence on youth in the community. The local police and the community members surveyed were also in agreement that police/community relations were largely positive. All stakeholders surveyed felt generally positive about the intervention program, but the community members were more skeptical of the program's ability to deter their children from trouble. Implications of our findings for the program and for future studies are discussed.

Spatial Concentration and Spillover: Eviction Dynamics in Neighborhoods of Los Angeles, California, 2005-2015

The lack of sufficient affordable housing in Los Angeles, California burdens many renter households with the threat of an eviction. Research has identified individual- and neighborhood-level sociodemographic correlates of eviction, but the uneven distribution of sociodemographic characteristics and housing conditions across neighborhoods likely produces broader patterns of spatial clustering in eviction prevalence across local areas. We use spatial autoregressive models to explain the spatial concentration and spillover effects for two types of formal eviction filings-court-based and no-fault Ellis Act petitions-within and across census tracts in Los Angeles. Court-based filings show greater and more persistent spatial concentration, particularly in neighborhoods with higher percentages of Black residents. We find evidence of spatial correlation for both types of eviction, however, suggesting that identifying the spatial distribution of eviction prevalence across local areas is important to understanding how location shapes eviction risk in metropolitan areas.

Changes in Neighborhood-Level Concentrated Disadvantage and Social Networks Among Older Americans

Close social networks provide older persons with resources, including social support, that maintain their well-being. While scholarship shows how networks change over time, a dearth of research investigates changing social contexts as causes of network dynamics. Using the first two waves of the National Social Life, Health, and Aging Project survey (N = 1,776), this study shows how rising neighborhood-level concentrated disadvantage through the Great Recession of 2007–2009 was associated with smaller close networks, largely due to fewer new close ties gained, among older Americans. Worsening neighborhood circumstances pose obstacles to older residents’ acquisition of new close ties, including heightened fear, lower generalized trust, stress and depression, and declines in local institutions that attract both residents and nonresidents.

Neighbourhood characteristics associated with child pedestrian fatalities in Johannesburg, South Africa

The present study investigated the relationship between neighbourhood characteristics and childhood pedestrian fatalities (2001-2010) in Johannesburg, South Africa. This cross-sectional study used negative binomial regression models. Results indicate that: areas with high concentrated disadvantage have elevated childhood pedestrian deaths, especially for those aged 5 to 9 years. Areas marked by residential mobility are associated with high pedestrian deaths among children 0 to 4 years. Black childhood pedestrian deaths are higher in areas marked by a high concentration of female-headed households. The analyses highlight the value of further exploring the effects of neighbourhood characteristics and suggest points of entry for interventions to reduce or prevent childhood pedestrian traffic mortality.

Neighborhood Social Determinants of Triple Negative Breast Cancer

Triple Negative Breast Cancer (TNBC) is an aggressive, heterogeneous subtype of breast cancer, which is more frequently diagnosed in African American (AA) women than in European American (EA) women. The purpose of this study is to investigate the role of social determinants in racial disparities in TNBC. Data on Louisiana TNBC patients diagnosed in 2010–2012 were collected and geocoded to census tract of residence at diagnosis by the Louisiana Tumor Registry. Using multilevel statistical models, we analyzed the role of neighborhood concentrated disadvantage index (CDI), a robust measure of physical and social environment, in racial disparities in TNBC incidence, stage at diagnosis, and stage-specific survival for the study population. Controlling for age, we found that AA women had a 2.21 times the incidence of TNBC incidence compared to EA women. Interestingly, the incidence of TNBC was independent of neighborhood CDI and adjusting for neighborhood environment did not impact the observed racial disparity. AA women were more likely to be diagnosed at later stages and CDI was associated with more advanced stages of TNBC at diagnosis. CDI was also significantly associated with poorer stage-specific survival. Overall, our results suggest that neighborhood disadvantage contributes to racial disparities in stage at diagnosis and survival among TNBC patients, but not to disparities in incidence of the disease. Further research is needed to determine the mechanisms through which social determinants affect the promotion and progression of this disease and guide efforts to improve overall survival.

People, Places, Power: Medicaid Concentration and Local Political Participation

The geographic concentration of disadvantage is a key mechanism of inequity. In the United States, the spatial patterning of disadvantage renders it more than the sum of its individual parts and disproportionately harms economically and racially marginalized Americans. This article focuses specifically on the political effects of Medicaid beneficiaries being concentrated in particular locales. After offering a framework for conceptualizing the community-wide consequences of such policy concentration, I analyze aggregate multiyear data to examine the effect of Medicaid density on county-level voter turnout and local organizational strength. I find that, as the proportion of county residents enrolled in Medicaid increases, the prevalence of civic and political membership associations declines and aggregate rates of voting decrease. These results suggest that, if grassroots political action is to be part of a strategy to achieve health equity, policy makers and local organizations must make efforts to counteract the sometimes demobilizing "place-based" political effects of "people-based" policies such as Medicaid.

The Spatial Epidemiology of Intimate Partner Violence: Do Neighborhoods Matter?

We examined whether neighborhood-level characteristics influence spatial variations in the risk of intimate partner violence (IPV). Geocoded data on IPV cases with associated protection orders (n = 1,623) in the city of Valencia, Spain (2011-2013), were used for the analyses. Neighborhood units were 552 census block groups. Drawing from social disorganization theory, we explored 3 types of contextual influences: concentrated disadvantage, concentration of immigrants, and residential instability. A Bayesian spatial random-effects modeling approach was used to analyze influences of neighborhood-level characteristics on small-area variations in IPV risk. Disease mapping methods were also used to visualize areas of excess IPV risk. Results indicated that IPV risk was higher in physically disordered and decaying neighborhoods and in neighborhoods with low educational and economic status levels, high levels of public disorder and crime, and high concentrations of immigrants. Results also revealed spatially structured remaining variability in IPV risk that was not explained by the covariates. In this study, neighborhood concentrated disadvantage and immigrant concentration emerged as significant ecological risk factors explaining IPV. Addressing neighborhood-level risk factors should be considered for better targeting of IPV prevention.
