To date, research into the subjective aspects of high density has focused mainly on the negative consequences of overcrowding. This study, in contrast, outlines some of the positive aspects of high density in neighborhoods, exploring the physical-spatial environment of two neighborhoods in the city of Haifa, Israel. It was found that while the relatively high residential density was similar in both neighborhoods (40 housing units per acre), this was more positively evaluated in one neighborhood as compared to the other. This can be attributed to some specific environmental and planning features. In particular, where physical planning enabled the potential advantages of high density to be realized, this was positively perceived and evaluated by local residents. Such advantages mainly comprised accessibility to a variety of services, more frequent public transportation, and access to open spaces within walking distance. Particularly advantageous were the increased opportunities for social gathering. At the same time, however, high density did not foster social relationships at the neighborhood level. The study further identified the gender and age groups that benefited most from the high density. Thus, women evaluated high density more positively than men. Young families with children and senior citizens (over 65) were also more likely to benefit, and to evaluate the high density environment more positively than other social groups.

Creating “community” has long been a goal of urban planners. Although such rhetoric abounds in planning circles, what it all means is unclear. In this article, the authors review the community psychology and urban plan- ning literature, defining sense of community within the context of how the built environment might facilitate or impede it. They then present their research, which tests the effects of “main street” on sense of community in four San Francisco neighborhoods. Results indicate that respondents in neighborhoods exhibiting characteristics of a main street town (Bernal Heights and West Portal) have significantly higher sense of community than do respondents from a high-density neighborhood (Nob Hill) and from a more suburban-style city neighborhood (Sunset).

This paper reports findings from recent research examining the relationship between urban design and layout and aspects of social and communal life in urban neighbourhoods. To address this, six UK neighbourhoods of varying densities and layouts were selected for detailed investigation. Data on social interactions, social activities and social networks along with perceptions of the built and social environment of the neighbourhoods were collected through observations, questionnaire surveys and secondary data sources. Neighbourhood design and layout were analysed using spatial network and visibility graph analysis methods. Correlation and multiple regression tests were conducted to test the claimed associations. Findings indicate differences between socializing patterns and structure of social networks in high- and low-density areas. Low-density areas were associated with widely spread social networks and activities with very few strong relationships. In high-density neighbourhoods, respondents had small networks but stronger ties were found. Detailed investigation shows that much of this can be attributed to, among other physical factors: the location of public spaces, visibility from and to these spaces, visual links between neighbourhoods', typology and physical form of development rather than density alone. This indicates that some of the negative social impacts found within high-density urban development might be rectified with better design of neighbourhoods. It is clear that to deliver sustainable development, the 'compact city' will have to be designed with specific spatial and built environment characteristics.

The existing literature on the social, personal, and health consequences of high density housing is unclear regarding the significance that can be attached to the physical features of housing. The present study, which is based on interview information collected in Hong Kong, is able to control for deprivations and stresses related to "poor housing," and it is also able to distinguish superficial from more severe measures of personal strain. High densities are seen to have very little effect on individuals and families, although there is a suggestion that congestion is a potentially significant stress.

We investigated the influence of neighborhood built form on sense of community in Perth, Western Australia. It was hypothesized that sense of community would be stronger in individuals living in pedestrian-friendly neighborhoods. Multivariate linear regression models explored associations between walking and sense of community, with progressive adjustment for objective and perceived neighborhood characteristics. Sense of community was positively associated with walking for transport and positive perceptions of neighborhood quality, and negatively associated with residential density. The findings highlight the influence of local area perceptions on sense of community that appeared to be more important than objective environment characteristics. However, the latter may influence perceptions, and this requires investigation.

Critics have long denounced the design of suburban communities for fostering political apathy. We disaggregate the concept of suburban design into four distinct attributes of neighborhoods. We then use tract-level Census data, the Social Capital Community Benchmark Survey, and multilevel models to measure the relationship between these design features and political participation. Certain design aspects common in suburban neighborhoods are powerful predictors of reduced political activity, illustrating a potential link between neighborhood design and politics. Yet low-density environments appear to facilitate some types of participation. Suburban designs vary, and so do their likely impacts on political participation.

This paper examines the opportunities for social activities in public outdoor spaces associated with high-density residential living. This study surveyed activities in outdoor spaces outside three high-density residential communities in Brisbane. Results indicated that activity patterns in public outdoor space outside residential communities are different to general urban public outdoor space. This broadly, but not fully, supports current theories concerning activities in public space. That is some environmental factors have impacts on the level of social interaction. The relationship between outdoor space and a residential building may have a significant impact on the level of social activities. As a consequence, a new classification of activities in public space is suggested. In improving the level of social contact in public outdoor space outside a residential community, the challenge is how to encourage people to leave their comfortable homes and spend a short time in these public spaces. For residential buildings and public space to be treated as an integrated whole, the outdoor open spaces close to and surrounding these buildings must have a more welcoming design.

To what extent does the density of the tree cover in a city relate to the amount of social capital among neighbors? To address this question, we linked social survey data (N = 361) from the Baltimore Ecosystem Study with socioeconomic, urban form, and green space data at the census block group level using a geographic information system. We found a systematically positive relationship between the density of urban tree canopy at the neighborhood block group level and the amount of social capital at the individual level (r = .241, p < .01). Multiple regression analyses showed that tree canopy added a 22.72% increase in explanatory power to the model for social capital. This research adds a new variable—neighborhood tree canopy—to the typologies of green space that affect human social connection. Trees are a relatively inexpensive and easy intervention to enhance the strength of social ties among neighbors.

Although many low-income urban areas are highly walkable by conventional measures such as population density or land use mix, chronic diseases related to lack of physical activity are more common among residents of these areas. Disparities in neighborhood conditions may make poor areas less attractive environments for walking, offsetting the advantages of density and land use mix. This study compared poor and nonpoor neighborhoods in New York City, using geographic information systems measures constructed from public data for US census tracts within New York City (N = 2,172) as well as field observation of a matched-pair sample of 76 block faces on commercial streets in poor and nonpoor neighborhoods. Poor census tracts had significantly fewer street trees, landmarked buildings, clean streets, and sidewalk cafes, and higher rates of felony complaints, narcotics arrests, and vehicular crashes. The field observation showed similar results. Improving aesthetic and safety conditions in poor neighborhoods may help reduce disparities in physical activity among urban residents.

A medium-density planned neighborhood designed for a centrally located piece of urban land in the 1970s invoked some specific social-mix targets for the residential population of some 850 dwelling units. The site plan was developed in accordance with explicit planning principles derived from the Pattern Language by C. Alexander et al. A postoccupancy evaluation of residents' status, attitudes, and behaviors suggests that the design of a successful environment for a socioeconomic population mix involves a delicate balance between privacy and community. Such a balance is more complex and requires more careful design and more subtle innovation than the simple "if-then" logic of the Patterns used in planning this neighborhood.

This paper assesses and synthesizes the cumulative results of a new “neighborhood-effects” literature that examines social processes related to problem behaviors and health-related outcomes. Our review identified over 40 relevant studies published in peer-reviewed journals from the mid-1990s to 2001, the take-off point for an increasing level of interest in neighborhood effects. Moving beyond traditional characteristics such as concentrated poverty, we evaluate the salience of social-interactional and institutional mechanisms hypothesized to account for neighborhood-level variations in a variety of phenomena (e.g., delinquency, violence, depression, high-risk behavior), especially among adolescents. We highlight neighborhood ties, social control, mutual trust, institutional resources, disorder, and routine activity patterns. We also discuss a set of thorny methodological problems that plague the study of neighborhood effects, with special attention to selection bias. We conclude with promising strategies and directions for future research, including experimental designs, taking spatial and temporal dynamics seriously, systematic observational approaches, and benchmark data on neighborhood social processes.

Urban sociologists and criminologists have maintained housing’s importance in providing individuals with a sense of security within their neighborhood. Yet it remains unclear whether all types of housing provide this sense of safety in the same way. This article provides an analysis of the relationship between dwelling type and fear of crime. Data from the 2009 Canadian General Social Survey are analyzed. Results suggest that living in a multiunit dwelling has no statistically significant impact on fear of crime in the neighborhood; however, individuals living in high-rise and low-rise residences are less likely to be fearful of crime while at home in the evening. One possible explanation for these findings is the fortress effect: High-rise buildings isolate individuals in physical space, providing security in the home, and creating physical and social distance from the rest of the neighborhood. The implications of these findings are discussed.

Residents in a neighborhood view physical disorders as a potential incubator for negative incidents. Even though the disorders may not directly bring serious crime to the neighborhood, the poor physical conditions may affect residents in other ways, including increases in perceived physical disorder and fear of crime and decreases in neighborhood satisfaction. Focusing on the effects of physical disorder, this study examined the underlying associations between the actual upkeep, perceived upkeep, and neighborhood satisfaction using a structural equation model. The findings confirmed interrelationships be- tween factors; confirmed that as some categories of actual upkeep improved, perceived upkeep and neighborhood satisfaction improved; confirmed that as perceived upkeep improved, perceived safety from crime and neighborhood satisfaction improved; and confirmed that as perceived safety from crime improved, neighborhood satisfaction improved. The structural equation model showed that actual physical upkeep factors each had indirect effects on perceived upkeep, safety from crime, and neighborhood satisfaction.

This study examined what factors best predict residents’ concerns about neighborhood safety. One-hundred and twenty-two participants were selected from a large, Midwestern metropolitan area. All participants lived in high crime areas. Participants completed a 22-item questionnaire that assessed their perceptions of neighborhood safety and vigilance. These items were clustered as: 1) Community care and vigilance, 2) neighborhood safety concerns, 3) physical incivilities, and 4) social incivilities. Police crime data were also used in the analyses. Our findings suggest that aspects of the broken window theory, collective efficacy, and place attachments/territoriality play a role in affecting residents’ concerns about neighborhood safety.

A number of recent studies have used surveys of neighborhood informants and direct observation of city streets to assess aspects of community life such as collective efficacy, the density of kin networks, and social disorder. Raudenbush and Sampson (1999a) have coined the term “ecometrics” to denote the study of the reliability and validity of such assessments. Random errors of measurement will attenuate the associations between these assessments and key outcomes. To address this problem, some studies have used empirical Bayes methods to reduce such biases, while assuming that neighborhood random effects are statistically independent. In this paper we show that the precision and validity of ecometric measures can be considerably improved by exploiting the spatial dependence of neighborhood social processes within the framework of empirical Bayes shrinkage. We compare three estimators of a neighborhood social process: the ordinary least squares estimator (OLS), an empirical Bayes estimator based on the independence assumption (EBE), and an empirical Bayes estimator that exploits spatial dependence (EBS). Under our model assumptions, EBS performs better than EBE and OLS in terms of expected mean squared error loss. The benefits of EBS relative to EBE and OLS depend on the magnitude of spatial dependence, the degree of neighborhood heterogeneity, as well as neighborhood's sample size. A cross-validation study using the original 1995 data from the Project on Human Development in Chicago Neighborhoods and a replication of that survey in 2002 show that the empirical benefits of EBS approximate those expected under our model assumptions; EBS is more internally consistent and temporally stable and demonstrates higher concurrent and predictive validity. A fully Bayes approach has the same properties as does the empirical Bayes approach, but it is preferable when the number of neighborhoods is small.

A lack of collective efficacy in neighborhood is associated with social and physical disorder and related anti-social actions. It is less clear, however, whether collective efficacy in neighborhood also enhances prosocial, other-regarding behavior. We studied this association by employing the Lost Letter Technique in a large-scale field experiment. Our data stem from 1,240 letters dropped in a representative sample of 110 Dutch neighborhoods, combined with neighborhood data based on a survey of residents (SSND2, n=996) and information provided by Statistics Netherlands. We distinguish between two conditions (1) location of the lost letter, that is, behind a car's windshield wiper on the sidewalk; and (2) type of addressee, that is, a Dutch name or a Turkish/Moroccan name. When we decompose collective efficacy into social cohesion and shared expectations of social control, we find that shared control expectations clearly matter for the rate of posted letters. Social cohesion has no effect. Furthermore, a high percentage of non-Western residents, high residential mobility, and a relatively low local income level are negatively related to the rate of posted letters.

Walking is important for the health of elderly people. Previous studies have found a relationship between neighbourhood characteristics, physical activity and related health aspects. The multivariate linear regression model presented here describes the relationships between the perceived attractiveness of streets for walking along and (physical) street characteristics. Two hundred and eighty-eight independently living elderly people (between 55 and 80 years old) participated in the study. Street characteristics were assessed along homogeneous street subsections defined as ‘links’. Positively related to perceived attractiveness of links were the following street characteristics: slopes and/or stairs, zebra crossings, trees along the route, front gardens, bus and tram stops, shops, business buildings, catering establishments, passing through parks or the city centre, and traffic volume. Litter on the street, high-rise buildings, and neighbourhood density of dwellings were negatively related to perceived link attractiveness. Overall, the results suggest that three main aspects affect perceived attractiveness of streets for walking, namely tidiness of the street, its scenic value and the presence of activity or other people along the street. The results are discussed within the context of these three aspects.

Ordinary kriging, a spatial interpolation technique, is commonly used in social sciences to estimate neighborhood attributes such as physical disorder. Universal kriging, developed and used in physical sciences, extends ordinary kriging by supplementing the spatial model with additional covariates. We measured physical disorder on 1,826 sampled block faces across four U.S. cities (New York, Philadelphia, Detroit, and San Jose) using Google Street View imagery. We then compared leave-one-out cross-validation accuracy between universal and ordinary kriging and used random subsamples of our observed data to explore whether universal kriging could provide equal measurement accuracy with less spatially dense samples. Universal kriging did not always improve accuracy. However, a measure of housing vacancy did improve estimation accuracy in Philadelphia and Detroit (7.9 percent and 6.8 percent lower root mean square error, respectively) and allowed for equivalent estimation accuracy with half the sampled points in Philadelphia. Universal kriging may improve neighborhood measurement.

Strategies that reduce fear of crime may contribute to improved health outcomes; however interventions require a better understanding of the neighbourhood correlates of both emotional responses to crime (i.e., fear of crime) and cognitive assessments of crime (i.e., perceived crime risk). This study explored the association between objective measures of suburban design and two safety outcomes: perceived crime risk and fear of crime, for participants who lived in new suburban housing developments in Perth, Western Australia. The characteristics of a walkable neighbourhood, particularly retail land, were associated with less fear of crime, but greater perceived crime risk. One interpretation is that ‘strangers’, attracted to the neighbourhood by diverse land-uses, might influence the emotional and cognitive as- pects of ‘fear of crime’ differently. Researchers interested in the impact of the built environment on ‘fear of crime’, and any subsequent influence of these perceptions on health, should be mindful that the environment appears to impact these constructs differently.

Most theoretical perspectives on neighborhood effects on youth assume that neighborhood context serves as a source of socialization. The exact sources and processes underlying adolescent socialization in disadvantaged neighborhoods, however, are largely unspecified and unelaborated. This article proposes that cross-cohort socialization by older neighborhood peers is one source of socialization for adolescent boys. Data from the National Educational Longitudinal Survey suggest that adolescents in disadvantaged neighborhoods are more likely to spend time with older individuals. I analyze qualitative interview data from 60 adolescent boys in three neighborhoods in Boston to understand the causes and consequences of these interactions and relationships. Some of the strategies these adolescents employ to cope with violence in disadvantaged neighborhoods promote interaction with older peers, particularly those who are most disadvantaged. Furthermore, such interactions can expose adolescents to local, unconventional, or alternative cultural models.
